Hi everyone
I have set up many fish tanks and I have never had this problem.
I re set up an old tank at work that had been used and completely cleaned by me 8 weeks ago.
It's approx a metre long.
I filled with tap water, put a clean filter in the tank. a few clean pebbles, no gravel and no fish.
the water looked sparkling clean, but the next morning the water was a revolting lime green.
I put sludge from my other large tanks filter in and the water went cloudy as expected and lime green wasn't so noticeable.
next morning silt from sludge on the bottom of the tank as expected but the water is still lime green and smelly.
I have not added fish or plants yet so not a case of over feeding, over stocking or waste
sorry I haven't had a chance to take my test kit in yet so I can't give you readings.
any suggestions?
thanks in advance
Deb
