Hello all - I am very new to aquarium world. have a 55 gal
freshwater tank that was left at my house so I now own it.
OK so I set it up and it was lovely for a number of months. Last month the water went all green. I put my fish in a bucket and emptied the tank and started fresh. New water filter set up and all fresh water. added/ algae treatment. water was clear for about two days.
I have 2 coi, 2 black mollies, a couple of larger goldfish, two smaller gold fish, a loach, a plecky and a bug-eyed gold fish.
I had aquatic (banana) plants in the aquarium that I took out but it made no difference in the water going green so it's not them.
I know I need to change the filters regularly; changed them out on Tuesday but no change to water.
I manage the same size tank with the exact same set up at my workplace and that tank stays clean & clear - we have danios, loaches, platys & gouramies in that tank.
is it the fish? any - and I do mean Any - assistance would be greatly appreciated. I really get a lot of enjoyment out of the fish and would hate to have to send them to another home because I can't take care of their home.
