Dave, it could very well be something else. I did mention that I am changing salt brands as well. It just seems funny that the only time it has done this in a year is when I was feeding the reed roids and when I quit feeding them it came back to it's usual self again in about 3 days. I have done one water change since I quit feeding and it did not have any effect on it. I am going to continue to feed rr to my 24g and just hold off for now on my other tanks until I have done a few more water changes on them.
