I suggest you look up the postings (roughly 10 years back) of member Aaron Matos. (I believe his member name is "AaronM".) Aaron had an elaborate water (cleansing) system which he ran the water from a 1/10 acre pond through to support a very high amount of fish biomass - successfully. Aaron's methods might be of interest to you in maintaining good water quality.
