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

Buy this every year, one tablet down the toilet each month. Never had any bad smells from the tank.

It has kept our septic tank clear for years…..so does its job

Seems to do the job, have been using a few years now and haven’t had to empty tank yet!

Seems to work well , new to having a septic tank so trying all ways to keep it working properly

great product does what its supposed to. Easy to use just pop it into the toilet bowl then flush. Purchased a few times now and will continue to do so.

Used it after tank was emptied

We have a Victorian brick septic tank and was unsure what I could use to keep the drains clear and the vent pong away. Seem to be working so far.

For obvious reasons it’s a bit difficult to tell how effective this is but I can say for certain that the occasional smell from drains and pipes has disappeared since we started using it. Will have a better idea when we next have the tank emptied but for the money worth a punt.
