Thanks for all the info. I do not use RO, all I use is well water. I have a
spare 25 gallon tank which I use for doing the water changes. I keep the
water in the spare tank for a month before I change. It is slowing
disappearing, I have cleaned all the filtration systems, skimmer etc, and
also have changed the timer on the lights, it has helped, all I need now is
patience.
Once again thanks for the info, the 2005 annual Marine Fish and Reef
magazine is excellent, it states all what everyone said.
