What were you expecting instant Amazon river water? Duh, last time I checked 6.5 is acidic. That is less then 7 above being alkaline. You can spawn an aweful lot of Apisto's in such water and it is easier to work with when you start with acidic water. The other units I was using were giving me water that held at Ph 7.5 so I see a clear cut diffrence. Personally I am using well water with a Ph of 5.5 and less then 30 microsiemans. And yes this is also acidic, I still have to treat it with peat to be succesfull with the more black water species. My RO is for my drinking water and my reef tank. --- Dave Gomberg <gomberg@wcf.com> wrote: David, can you say something about why your Spectapure puts out acid water? That doesn't fit with my model of how these guys work. Please advise. Dave If you would like any further advice Dave I would advise that you go call their Tech support line and get it from the horses mouth. www.spectrapure.com They are very nice and they cater to hobbyists. Good luck with you RO sytem. _________________________________________________________ Do You Yahoo!?
