envii Septic Klear, Septic Tank Treatment & Cleaner, 12 Months Supply, Bacteria Booster Enzyme Tablets Remove Smells and Unblock Septic Tanks

It works. It is easy to use. I was cynical but am converted.

We disccovered this item when our septic tank got out of balance and became a bit whiffy (drain smells coming back throught the plug holes, etc). The reviews convinced us to try them.Amazon quickly despatched them and within a couple of hours after their arrival, things were starting to smell much better. We use a tablet in each one of our four toilets on the first day of every month, and we've not had a problem ever since; just put one in the bowl and let it disolve for 5 to 10 minutes then flush.Two years later, we're still using them and very happy!

Most people whose plumbing is not connected to mains sewers know that septic tanks can be problematic. This product is as good as other more expensive versions I have used to alleviate odours and keep the tank clear and is thus good value. None of these bio- additives work perfectly but this one is pretty good.

Ideal for Septic Tank

Good

Used it after tank was emptied

I’ve come back as I’m about to buy some more for the next year and I have to say these are amazing. We have lived at the it property for one year now and previous owners for two years never did anything with their system. We use these once a month and we have never had a single problem. For the peace of mind, these are brilliant

Easy to use but impossible to determine if it really works
