David Lonergan & Michelle Cranna, Sydney, Australia:
”Despite having a three year old Koi pond with crystal clear water and healthy fish, our nitrate level was over 200. We do frequent water changes but as quickly as the nitrate reading goes down, it then returns to high levels. We managed to get the nitrate level down to around 120 with water changes.
After installing Clarity for only 13 days, nitrate has come down from 120 mg/l to 40 mg/l, and phosphate from 0.25 mg/L to <0.1 mg/L! The other parameters of our pond which was good are constant. These readings are doing a great job of convincing us that the Clarity Unit does reduce nitrate and phosphate which is what we wanted for our pond. In fact I must say we are totally thrilled with the product because it has also made our water crystal, crystal clear. We thought it was clear before, everyone who looks at our pond says we have the best water they have ever seen, but now the Clarity has taken our water quality to this even higher level, a fantastic standard. Now we won't have to do all those constant and time consuming water changes. The fish are also doing very well, I think their colours look more vibrant and the white seems brighter too.“
