Well, I bought the Reverse Osmosis Water Filtration System. Got the Wells for $140 from Costo($160 from Sams). It's a five stage by Watts. Not that this has a lot to do with water chemistry in ponds unless you want to fill an aquarium or something, but a subject of interst none the less. It seems that people that own ponds also live in the country, and have well water to contend with. WQ is always of concern if it's in the pond, in the sprinkler system, or in the house.

Anyway, the system is rated at 25 gal/day, and I've hooked it up to my ice maker also. If anyone is interested in installation or the scoop on performance, PM me. Thier web page nore there installation instruction tells it all, but I think it's a good product. It needs quite a bit of space below the sink as it's quite large, and needs maintenance about every six months. I've tasted the water, and this should get you off the bottled water. Based upon the original question, this should help with the iron and hardness in the drinking water for purposes of consumption.

You guys can tell me if I'm all wet. I'm an environmental engineer and worked on groundwater contamination on military installations, primarily TCE and other chlorinated hydrocarbons. We've installed numourous pump and treat systems and iron fouling has been a major problem. Iron bacteria and fouling will close off an 8" pipe in a couple of years and shut a system down. The same with wells. I've noticed a lot of accumulation in the toilet tank of my house which leads me to think about my well. Talk about a tough question, chlorine treatment (sodium hypochlorite)can abait the bacteria and iron accumulation in the well but can also kill the septic tank. I'm sure you don't want to flush the well rinse into your pond or on the grass. M, your thoughts?
