Envii Septic Klear

The easiest, safest solution to eliminating and preventing smelly septic tanks. One natural tablet a month will keep your septic tank clean, operating efficiently, and most importantly, stench free.

Available in 12 or 24 tablet packs.




Envii Septic Klear is a natural product that maintains an effective and efficient septic tank. It is important to use septic tank tablets regularly to reduce the build up of waste inside your septic tank. If this waste is left to accumulate, it can lead to problems such as sewage smells and sewage backing up.

Unique beneficial bacteria

Our septic tank tablets use unique beneficial bacteria and enzymes to target the waste in your septic tank and break it down. They digest the organic waste and convert it into safe levels of oxygen and carbon dioxide. This is a natural process that happens in septic tanks and is how they are designed to operate. However, as our tablets contain high levels of bacteria and additional nutrients, this process is accelerated.

When used monthly, Envii Septic Klear keeps septic tanks clean and running efficiently. As a result, this will eliminate the need to have the tank emptied which can cost hundreds. If your tank has just been emptied, use 2 tablets to replenish the bacteria that have been removed.
