So this is random, but I work at Menards, and in our garden center, we carry a bunch of stuff for ponds, like water conditioner, barley and peat extract, etc. A lot of it is junk (at least I think so, like extra bacteria? Once it's cycled, can't you stop adding bacteria? Anyway....) Is any of it good for a smaller indoor tank? It's all TetraPond brand, which I know isn't the best, but one bottle is like $6 and treats close to 2500 gallons, which to me seems like a great deal. Your thoughts on this? We have huge external canister filters and pumps too.
