I have a 40gal gold fish tank- with 2 fancy goldfish and 2 small asian algea eaters.
I noticed about a month ago my goldfish tank was getting cloudy and when I do water changes- up to every 2-3 days right now, the water is a cloudy green color.
I went to several lfs
and was told:1) you filter is broken-so I bought new filter and it is working well- Wisper 40i- and am almost thinking to put another wisper 40i in it if it would help, 2) that I needed to add have an algea eater in the tank- well I previously had a pluco but it decided my goldfish tasted better, so I got to small asian algae eaters instead and so far they are keeping the algae under control but the water is still green, 3) I was told that its an algae bloom and I need to increase my water changes and it will clear up in a month- well im doing changes ever 2-3 days and its almost been a month and no change, and 3) Lastly, I was told I need to change my florescent light- the lfs
said they only last about a year and then as it gets older the light frequency changes or something and it helps build algae in the water.
So, by now I am soo tired and worn out- all my water levels are normal and running stable. If I do an 70% water change the water is pretty clear for a night then gets cloudy over a day or two so Im kinda at my wits end....
can anyone provide some ideas? is it really the light? or is it something else. I really dont want to use more chemicals- I already use a water conditioner, easy balance, aquarium salts, a biochemical or whatever it is.
