I have a question about a particular use of copper as an algae killer. I know the staining issues with copper and am aware that many do not like it for this reason. I use copper in a slightly different manner and have had wonderful success with it. On yearly opening, and on the rare occasion I have water problems due to low Chlorine(vacation or business trips away from home), copper has been an easy answer that has not stained anything. I bought a large supply of 99.8% elemental copper that is commercially designed to kill algae in ponds. I paid $21 for it a long time ago. There is more copper in that bucket than $2000 worth of commercial pool algecide would have in it. The beauty of this stuff is that it will clear up a light bloom or a swamp in 48 hours and it will do it without using much chlorine. Where I favor it over the chelated coppers is that once it has done its job, I can get it out of the water very easily. I put enough of it in the watter to turn the water an opaque cloud. I filter for 48 to 72 hours. I usually have to back wash three or four times during that process. Each backwash is loaded with blue colored dead algae. During the two to three days I do this, the water clears up some but, it still remains visibly cloudy. When the algae is dead, I add Zeo Fiber to my sand filter. I let the filter run until the pressure reaches 20psi. It usually takes a day and a half to two days for this to happen. By this time, the water is sparkling clear. I backwash out a huge mess of blue zeo fiber containing dead algae. After backwashing the Ze0-Fiber, the copper is gone from my water. I add Zeo fiber back to the sand filter and usually its ready for a backwash in about a week. After that back wash, the copper will test at zero. I am sure its not truly zero, but its definitely not high. Nothing has ever gotten stained during the process. I am using $1 worth of copper and $2 worth of Zeo Fiber to do what I would use $30 worth of chlorine to do. So far, I have never observed a negative side effect from this process. I keep the pool swimmable during the entire process. I doubt anyone with blonde hair would want to get in, but its not going to stain my Cherokee Indian hair.
Is anything wrong with this?
Is there something I am over looking?
