Three Foot KOI With A Dramatic Water Garden Bottom

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 copper residual was never measured in the primary pond, probably attributed to the two 900lb bubble bead biological filtration systems. Price put in 2 Zeolite filters with an oxygen device to protect against ammonia buildup due to the large KOI, harmful equally to the Koi and all their water garden floras. A Co2 pH injection strategy was in fact essential to prevent the fish pond from hitting the 8.0ph which existed in Price's well, notably following the regular KOI feeding. PH was finally retained in a 7.2 to 7.6 range by utilizing carbon dioxide being injected 24/7 and backed up by a sulphuric acid injector that kicked in through sensors any time pH values hit 7.5.

The pond struck 80-90% transparency on a frequent schedule, even so it was not acceptable for Price and the fish pond at the same time produced intermittent string algae. With his wife's, the veterinarian, assistance Price came to the conclusion to present copper to the fish pond to get rid of the string algae and aim for 95-100% day-to-day transparency in the twelve foot deep pond. Through daily supervising of the copper concentrations, .10, .15, .20 and ultimately .25ppm copper was added with the KOI fish supervised. Price documented at .25ppm his fish "were not happy" and levels ended up being scaled back to .15ppm - - sufficient to eradicate string algae and get clarity to almost "mirror quality".

"The very low level of copper provided a look at of the Black EPDM liner defects in places the water garden struggled. It is a remarkable clarity" said Price. The typical do it yourself fish-pond consumer may likewise get results in simpler pond or stream environments from the scale control, O2 oxygen managing ammonia levels and the glass filter media.
