Subj : The Mystery Almost Solved To : Jeff Snyder From : Michael Grant Date : Thu Jul 02 2009 07:07 pm Hello Jeff. 29 Jun 09 04:26, you wrote to me: JS> The root of your problem is more than likely excessive organic waste JS> somewhere in your system, which over time is being broken down into JS> nitrates.

It very likely is nitrates in the substrate that's the problem, but it's a lot bigger problem than a turkey baster or a gravel vaccum (which I /have/ used recently) can take care of. That's why I need to do a teardown, to remove the substrate and completely clean it, in order to get the situation under control. I'll probably do it this weekend. --- GoldED/W32 3.0.1 * Origin: MikE'S MaiL MaCHinE! (1:250/306) .
