Thank you for all your advise, but really what waffers are you feeding I might want to get some of that brand if they are as large as your suggesting. Also snails will eat the the waffers.
They are about the size of a nickle (0.05 cents)
Also, if you feed too much wafers they will not eat any algae.
Put a wafer in a cup of water for a day and see how big it gets, then realize how big your fish and snails stomach are and think about how much food they can stuff in their belly's.
They don't need to eat to get full every day. Feed them what they can eat in a day 2 or 3 times a week and see how they are doing.
