Annual maintenance every 6 months keep my tanks and field line working. Without it the field lines get sluggish. K57 works good too.

We had a very bad smell from our tank and now the Oder is gone for now. Curious to see how long it lasts .

Did not dissolve as well as I had hoped. Lots of fatty deposit left after multiple treatments. Am ambivalent a to whether it is effective or not.

We moved to our home 2 years ago. We'd never been on septic before. Read about this stuff and started using it right away. We have 1250 gallon tank and use 64 oz every 6 months. I had a septic company come to check the sludge level and there might have been an inch in the test tube. The tank was pumped 4 years ago. We are a family of 4 (3 girls). The septic guy said, "whatever you're using, keep using it!" and said I should have it checked in a couple more years. I'll report back then! I have confidence it does whatnot claims to do - help break down sludge.

I added this and they’re leach field liquid to try and help my leach field and I’ve seen no difference waste of money

My 1000 gallon concrete septic tank is about 40 years old now, and I cleaned out, and doubled the leach field about 8 years ago. The field is what typically fails, NOT the tank. As stated, I have been using Roebic K37 since I bought the house 21 years ago. When it first came out, it was once a year, now they are recommending 4 times a year??? One or two people in the house, twice a year is enough. The number of people using the services is what controls usage. Also, if you have a 1000 gallon tank that has a foot of sediment on the bottom, it IS NOT a 1000 gallon tank, but more like an 800 gallon tank. Also, if you dump salt from a water softener (a real NO NO) into the tank, you should use it monthly, as salt kills the microbes.
