Your septic system usually shows visible signs when it needs attention. Common warning signs include:
If you notice any of these signs, your septic system needs immediate attention. A shock treatment can often fix these problems without expensive repairs.
Septi + is our flagship biological treatment product for regular maintenance of septic tanks.
It is made with bacteria and enzymes that break down organic matter, help to purify the wastewater, and protect the leach field. Septi + contains 1 billion bacteria per gram (CFU = 1×10⁹/g).
The enzymes produced by the bacteria include:
Regular use of Septi + helps extend the life of your septic system and prevents clogs from forming. Simply pour it into the toilet monthly and flush.
For best results, use Septi + once per month for regular maintenance.
Monthly treatment ensures:
Simply pour one dose into your toilet and flush. The bacteria will travel to your septic tank where they multiply and work continuously.
If you have a larger household (5+ people) or heavy water usage, you may benefit from using it twice per month. Contact us for personalized recommendations based on your specific situation.
Your septic system must break down a large amount of organic material (soaps, grease, feces, toilet paper, food residues, detergents, sanitizers, etc.) from the discharge on a daily basis.
The natural process of biodegradation is often insufficient to properly digest all these organic materials. This can lead to:
By adding bacteria and enzymes, you boost your septic system. The bacteria produce enzymes that break down organic matter more effectively, helping to:
Regular use of Septi + (monthly) can save you thousands of dollars in repairs or replacement costs.

Yes! In about 80% of cases, you can avoid replacing your septic system with a shock treatment.
Many homeowners with a clogged leach field are told the only solution is to replace their entire septic system (costing $15,000-$50,000+ depending on the system type). But is replacement really necessary? In most cases, no. The clog is typically biomat buildup, which our shock treatments can break down and eliminate.
Our shock treatments (SeptiMax or SeptiDrain) can:
When you SHOULD replace your septic system:
Try a shock treatment first - it's much more affordable than replacement and works in most cases!
A shock treatment is a biological way to clean a septic system using concentrated bacteria and enzymes. A shock treatment is performed for one of two reasons.
1. To solve clogging problems:
We suggest a moderate or intensive shock treatment in case of clogging of your leaching field. Both SeptiDrain and SeptiMax will be used and will allow an optimal treatment of the septic system.
2. To begin the maintenance treatment:
If you have never treated your septic system with bacteria and enzymes, we suggest that you opt for a basic shock treatment. This will allow you to clean your septic system before starting the regular maintenance with Septi +.
Simply pour the products into the toilet, flush, and the bacteria will take care of the rest. We observe an 80% success rate for clogged systems.
Shock treatments are customized based on your specific situation and needs. Every septic system is different, which is why we offer personalized treatment plans.
How to get your personalized treatment plan:
Based on your specific situation, we will:
General approach: Most shock treatments involve multiple applications over 2-4 weeks, but the exact protocol depends on factors like the severity of your clog, system size, household usage, and specific issues.
Each shock treatment package includes detailed instructions tailored to your situation. Contact us for your free personalized consultation!
Most important: Follow your local regulations. Some municipalities require pumping every 2 years, others every 4 years. Always check your local requirements first.
Generally, septic tanks should be pumped every 2-4 years, but this depends on several factors:
Factors affecting pump frequency:
With regular Septi + maintenance:
You can often extend the time between pumpings because the bacteria help break down solids more effectively, reducing sludge buildup.
Important: If your tank is filling up too quickly or you notice slow drains, backups, gurgling pipes, or odors, these are signs of a malfunctioning septic system, not just a full tank. There's usually an underlying issue like bacterial imbalance, too many solids going down drains, or a clogged leach field. Contact us for a free consultation to diagnose the problem.
We recommend having your tank inspected by a professional every 2-3 years and pumped when the sludge layer reaches about 1/3 of the tank depth.

General tips:
Our bacterial products are much safer than harsh chemical alternatives like drain cleaners or bleach!
A clogged leach field is usually caused by biomat buildup - a thick layer of organic material that forms in the soil and blocks water absorption.
Main causes include:
What is biomat? Biomat is a dense, gelatinous layer that forms where wastewater meets soil. Over time, this layer becomes impermeable and prevents proper drainage.
The solution: Shock treatments contain concentrated bacteria that can break down biomat and restore drainage in most cases.
We offer several shock treatment products depending on your specific issue:
SeptiMax - Most powerful shock treatment Our most concentrated product in bacteria (CFU = 4×10⁹/g). It's used in shock treatments to break down the most persistent organic matter.
SeptiDrain - For clogged drain fields Liquid formula that contains both bacteria and a powerful biosurfactant. It's used to unclog drains and clean septic fields. The biosurfactant allows bacteria to adhere more easily to the surface to be treated. Available in multiple sizes: 1L, 4L, 10L, and 20L.
Basic, Moderate, or Intensive packages: We offer complete shock treatment packages with special discounts combining SeptiDrain and SeptiMax for optimal results. Visit our shock treatments page for package deals.
Contact us at 1-800-378-6132 for personalized advice on which product is right for your situation.
It depends on the product:
Septi + (Monthly maintenance): Pour into the toilet and flush. The bacteria will be carried by water to your septic tank where they become active and multiply.
SeptiMax (Shock treatment): Mix with water, pour into the toilet, and flush. The bacteria will travel to the septic tank and gradually be carried to the leaching field.
SeptiDrain (Shock treatment): You have two options:
SeptiClean (Household cleaner): Spray directly on the surface you want to clean (bathtub, sink, shower, floors, cabinets, furniture, etc.).
Septi-RV (RV holding tanks): Pour into your RV toilet and flush.
If you're unsure, contact us at 1-800-378-6132 for guidance.
Protecting your septic system starts with what you put (or don't put) down your drains.
Never flush or pour down drains:
Why these harm your system:
Safe for septic systems:
When in doubt, throw it out (in the trash, not the drain)!

No! Our bacteria are completely safe for your lawn and garden and can even be beneficial.
Why it's safe:
Potential benefits: If your septic system drains properly, the treated wastewater can actually provide nutrients to plants and grass (which is why grass over and near your drain fields is often greener).
Important notes:
What to avoid on your lawn:
Our products are designed to work safely within your septic system and have no negative impact on landscaping.
Septic odors indicate that your system isn't working properly. Common causes include:
Inside your home:
Outside your home:
Solutions:
If odors persist after trying these solutions, contact us for personalized advice.
Both are shock treatment products, but they work differently:
SeptiMax:
SeptiDrain:
For best results with clogged systems:
We recommend using BOTH products together in our moderate or intensive shock treatment packages. Typically, SeptiDrain is used first to clean the leach field, then SeptiMax is flushed through the toilet to continuously send bacteria through the septic tank toward the leach field. This combination provides optimal treatment for the entire system.
Contact us at 1-800-378-6132 for personalized recommendations based on your specific situation.
No, you cannot "overdose" your septic system with our bacterial products. Using more product than recommended won't harm your system, but it's also not necessary and would be wasteful.
Our recommended dosages are optimized for effectiveness and cost-efficiency. The bacteria will multiply naturally in your septic tank, so following the recommended amounts is the best approach.
For best results:

You can use bleach and household cleaners in moderation, but excessive use can harm your septic system.
The problem with harsh chemicals:
Guidelines:
Better alternatives:
If you must use harsh chemicals, add Septi + afterwards to restore bacterial balance.

The bacteria are completely natural and biodegradable - they simply become part of the natural ecosystem.
The lifecycle of septic bacteria:
In your septic system:
After leaving the system:
Why this is safe:
No buildup: The bacteria don't accumulate or cause problems. They exist in balance with available food sources, much like any natural ecosystem.
This is why monthly Septi + treatments are necessary - you need to replenish the bacteria regularly since they're constantly being used up and flushed out of the system.
Results vary depending on the severity of your septic system issues and which treatment package you chose.
Typical timeline:
Factors affecting treatment speed:
For best results:
What if I don't see results?
We recommend observing your system for at least one month before taking action:
SeptiClean is our all-purpose enzymatic cleaner for household surfaces.
Uses:
What makes it special:
Note: SeptiClean is designed for surface cleaning. For drain or septic system issues, use our specialized products (Septi +, SeptiMax, or SeptiDrain).
The bacteria start working immediately once they reach your septic tank, but visible results depend on the severity of your problem and which product you're using.
For regular maintenance (Septi +):
The bacteria work continuously to break down organic matter. Results are ongoing and preventive rather than immediate. Your system stays healthy and problems don't develop in the first place. If you have odor issues, you may notice improvement as the bacteria restore balance to your tank.
For shock treatments (SeptiDrain/SeptiMax):
Typical timeline:
Factors affecting treatment speed:
Important: Minimize water use for the first 24 hours after a shock treatment to allow bacteria to establish. After that, normal water use is fine - the bacteria will continue working.
What if I don't see results?
We recommend observing your system for at least one month before taking action:

Why this is safe:
No buildup: The bacteria don't accumulate or cause problems. They exist in balance with available food sources, much like any natural ecosystem.
Why monthly Septi + treatments are necessary: Bacteria populations in your septic tank face constant challenges. They are killed by harsh cleaning products, pH imbalances, antibiotics flushed down drains, and other unfavorable conditions. Additionally, bacteria are continuously flushed out of the system. Regular monthly Septi + treatments ensure you always have enough of the right types of bacteria to properly attack and degrade all waste in the tank, maintaining optimal system performance.

Our shock treatments successfully fix septic system problems in 80% of cases (4 out of 5 customers).
What this means:
When shock treatments work:
Shock treatments are effective when septic problems are caused by:
Note: If organic matter has accumulated for a very long time, it may be harder to decompose and could require more time or multiple shock treatments. The bacteria need time to work through heavily compacted buildup.
When they might not work (20% of cases):
Shock treatments cannot fix physical or structural problems:
Even if replacement is needed: A shock treatment is worth trying first - it costs a fraction of replacement and works in most cases!
We've helped thousands of homeowners across Canada save money and avoid unnecessary excavation.
Septi-RV is our specialized bacterial treatment designed specifically for RV and boat holding tanks.
Why it's different: RV holding tanks face unique challenges - limited water, temperature fluctuations, chemical toilet additives, and compact spaces. Septi-RV is formulated to work in these conditions.
Benefits:
Perfect for RV owners, boaters, and anyone with portable holding tanks who wants an eco-friendly, effective solution.
Yes! SeptiDrain can help with clogged or slow drains in your house, especially when the problem is related to your septic system.
When SeptiDrain works well for household drains:
How SeptiDrain helps:
SeptiDrain is a liquid bacterial product that:
Important note: If only ONE drain is slow (like a single sink), the problem is likely a localized clog in that specific pipe, not a septic system issue. For single-drain clogs, a mechanical solution (plunger, snake) may be more appropriate.
Best results: Use SeptiDrain as part of a shock treatment package (combined with SeptiMax) for comprehensive septic system cleaning and drain restoration.

Excessive water use is one of the most common causes of septic system failure. Here are practical ways to reduce water usage:
Bathroom (biggest water user):
Kitchen:
Laundry:
Why it matters: Your septic system needs time to treat wastewater. Too much water too fast overwhelms the system, sending untreated wastewater to your drain field and causing failure.
General rule: Try to use no more than 50-75 gallons per person per day.

Yes, our bacterial products do have a shelf life, but they remain effective for a long time when stored properly.
Typical shelf life (when products start to lose effectiveness):
Important: These timeframes indicate when products begin to lose effectiveness, not when they become unusable. Bacterial count may decrease over time, but the products can still be used.
Storage tips for maximum shelf life:
Signs your product may be losing effectiveness:
Powder products (Septi +, SeptiMax):
Liquid products (SeptiDrain, SeptiClean):
Note about separation in liquids: Some separation is normal in concentrated bacterial products like SeptiDrain. Shake well before use.
Can you use older product? The product won't harm your system, but bacterial count may be reduced, making it less effective. For best results, use fresher product when possible.
Water tracer tablets (also called dye tablets) are diagnostic tools to detect leaks and track water flow in your septic system.
How they work: Drop a tablet into your toilet, flush, and the water turns bright green. If you see green water where it shouldn't be, you've found a leak or problem.
Uses:
When to use them:
Available in packs of 8 tablets. Safe for septic systems and won't harm bacteria.
We generally don't recommend using a garbage disposal with a septic system, but if you do use one, take precautions.
Why garbage disposals are problematic:
If you must use one:
Better alternative: Compost food scraps instead! It's better for your septic system and great for your garden.
While Bio-Sol products are safe, here's what to do if accidents happen.
If you spill the product:

Biomat is a thick layer of organic matter (biofilm) that accumulates in your leach field over time. It's the #1 cause of clogged drain fields.
What causes biomat:
Why biomat is a problem:
When biomat builds up in your leach field, it clogs the soil pores, preventing water from draining properly. This causes:
How to prevent biomat buildup:
1. Use monthly Septi + maintenance:
2. Avoid harsh chemicals:
3. Watch what goes down your drains:
4. Reduce water usage:
If biomat has already formed:
Use a shock treatment with SeptiDrain and SeptiMax. The concentrated bacteria and biosurfactants in SeptiDrain are specifically designed to break down biomat buildup and restore proper drainage.
