I know this is a little late but I have found something that actually works. It is a small plastic sinker that you put these packets of dried bacteria in. You only replace them every 30 days. It says it will do tanks up to 500 gallons, I have them in my automatic water tanks that are about 100 years old so they are really rough on the inside and I can't keep them clean. I didn't put this in before because I was still testing it. I put these packets into two separate tanks, one clean and one full of funk. The clean one never got green, I waited and checked and thought nothing was happening in the nasty tank. I kept checking and in four weeks I was about to pull the piece of @$#! out of the tank and my husband ( the one who bought the things) stuck his hand in and all the stringy green crap disintegrated in his hands and now they are beautiful! The cows and horses never acted like the water tasted different. It is non toxic, 100% natural, and Vet approved.
It cost 25 bucks for a 6 month supply. and 25 bucks for refills.
maybe we are lucky but I haven't scrubbed a tank (but the tester tank) all year!
