Clear Water With Fish And Water Garden

By Larry Couture


Dale Price experienced absolutely no illusions that a 60,000 gallon fish-pond would run translucent together with the "natural" biological filter systems recommended by local fish-pond designers in the middle of the 1990's. Price understood that when the KOI fish developed he would likely be breaking every last pound per gallon rule of thumb in the KOI textbooks. With his spouse, a veterinarian, he embarked about a 1 year set up and water treatment plan attempt to possess one of the most precious KOI collections in the U.S. showcased in dramatically clear water with completely unique flora on the pond's bottom.

The pond is 12 feet deep, oval in design and equipped with a detailed water garden bottom. A small but effective peninsula projects in order that Price can ring his liberty bell to call fish for feeding, often from the hands. Price first set out with a 30 GPM ionization together with oxygenation well water turbo model to remedy his household, irrigation and auto fill demands for the pond. The natural oxygen and ionization chambers for the household resulted in .10 to .15 ppm residual copper going into both his house and the pond on the replenishment water.

The residual was never tested in the primary pond, more than likely attributed to the two 900lb bubble bead biological filtration systems. Price installed 2 Zeolite filtration systems with an oxygen model to reduce ammonia accumulation produced by the bigger KOI, hazardous both to the Koi fish and all their water garden plants. A Carbon dioxide pH injection process was in fact also necessary in order to prevent the pond from approaching the 8.0ph which existed in Price's well, in particular immediately following the regular KOI feeding. PH was in the end preserved in a 7.2 to 7.6 range by using carbon dioxide injected 24/7 and furthermore backed up simply by a sulphuric acid injector which kicks on by means of sensor when pH levels reach 7.5.

The pond hit 80-90% clarity on a regular basis, even so definitely not good enough for Price and the pond at the same time generated recurrent string algae. With his wife's, the veterinarian, advice Price came to the conclusion to add copper to the pond to get rid of the string algae and strive for 95-100% daily clarity in the 12 foot deep fish-pond. With regular supervising of the copper concentrations, .10, .15, .20 and finally .25ppm copper was added with the KOI fish monitored. Price noted at .25ppm his koi "were not pleased" and levels ended up being scaled back to .15ppm - - just enough to eradicate string algae and bring clarity to almost "mirror quality".

"The lower concentration of copper supplies us an observation of the Black EPDM liner blemishes in areas the water garden was lacking. It is a extraordinary transparency" said Price. The typical do it yourself fish pond individual could even benefit in smaller and easier fish-pond or stream environments with the scale control, O2 oxygen controlling ammonia levels and the glass filter media.
