My son is working on starting a new fish tank. We have a 29 gallon tank and we got fish and have subsequently had a massive algae bloom that caused us to loose everything in the tank. We got it cleaned out and have begun cycling it to prepare for when we get new fish. In the meantime, we've done a little research to see what we may have done wrong. I think the 2 biggest issues was my son misunderstood me when we were discussing feeding fish and was giving the 1 pleco 2 algae wafers twice a day and I think we also overcrowded the tank. We had 6 tetras (3 different types), 6 plates (2 different types) 2 dwarf gouramis, 3 black mollies, and 2 snails. I guess before going into what he's thinking he wants when the tank finishes cycling I am wondering if I am on the right track for what went wrong with this first attempt. Any advice I appreciated.
