Hello
Me again, is the water pea-soup?
If so try:-
The drastic method is this - cover the tank with large towels so that no light can get in. Leave it for 3 to 4 days and do not feed your fish over this time. Remove the towels and do a 20% water change. This usually kills off all the pea soup algae.
I'm not sure if this works and only got it off a web site so it may not be true.
Good luck n will keep lokking for ya.
