I'm new to this whole aquarium experience ! My 3 1/2 year old wanted a fish and I was told that bigger tanks were easier to control than little ones! I set up the tank and let it run for a couple days and maintained a temp of 78, I was told to buy tetra safe start to jump start the bacteria! I did just this and 3 fancy guppies and 2 zebra dianos! After just 24 hours 2 guppies have died making my self pretty sad about it, I have read just about every thread I could possibly come accross and nothing is helping! I have a 20 gallon tank water temp is maintained at 78 and ph 7! I read in to the gh
but was told that I just needed to worry about the ph! Needless to say since then I have killed 2 more leaving 1 zebra diano to suffer! He is not looking too good! Any help,is much appreciated!
