I've seen the AquaBella water treatment at a lfs. Claims that you won't have to change water for a year. Somehow, after keeping cichlids for so long, I kind of doubt that. Anyway, it is 4 syringes, put 1 a day in the tank, supposed to be good for 5-55 gallons. I think I might try in my 75, not sure if 1 pack would work or have to get 2. Kind of pricey, 27.99 a treatment. Sounds too good to be true, that you can complete set up a tank with 4 syringes of bacteria and whatever else is in this stuff. Still might be worth trying. Anybody else ever seen it or used it?
