I know the rule is 1in per 10gal. So I have about five times too many fish.

Ouch, that rule is for inside aquariums w/tropical fish, not outside
set-ups. If we're talking goldfish, with good filtration, it is 20 gallons
per fish.

Could not keep the algae under control.
Bought a 500gal UV canister filter Nursery Pro Ultra Clean. Problem fixed.
I clean it about once every three weeks. The water is crystal clear.

UV will clear the water, but it won't let you know if that clear water is
clean water. Glad to read in later thread that you've purchased tests kits.
In particular I hope you got Ammonia, Nitrite, KH & pH, and since you have
UV NitrAte also. So what readings are you getting? ~ jan
