Forgive me if this information has already been covered. This is my first visit to this site and am hoping someone can help me out.
My partner and I own an aquarium service and maintenance business and have a problematic tank. The TROUT tank is only chilled tank we have and I know nothing about it as it was set up by a previous business. The owners have all sorts of problems and I am trying to sort out the issues.
This is a 440 gallon tank with a bioball set up underneath. It uses a sump, UV
sterilizer, canister filter, center dump with return jets around the column.
The problem is that we have major algae infestation and the owner will not let me use algae fix. So I am doing huge water changes, running a filter machine, and holding my breath. I think the water temp may be an issue as it is set at 60 degree F.
What else can I do besides trying to lower the temp and limit UV
light? Can I use algae fix and not harm the trout?
Also, can I add crayfish to clean the rocks/gravel etc?
Any advice would be appreciated to include a resource I can call and discuss the problems with. I lost the customer once and then they fired the other maintenance outfit because they were worse than me! Hard to believe.
