Alfie, I have a "puddle" of a pond with a home made filter which is 6 years old now & overstocked as most probably are. I have a 15W UV & loads of air going into the filter & pond via a Secoh SLL-40 air pump.
I test regularly for ammonia, nitrite, nitrate, pH, kH & TDS just out of interest.
Don't foget, the fish are happy in green water, it's only us that don't like it as we can't see them !
