Thoughts on unnexplained (and very sad) die-off

[jostafew]

Just did a copper test on the new system, I thought I saw a reaction (color change) at the beginning of the test but giving the test time to develop yielded no measurable result. Nonetheless I've done some reading on copper and heavy metal poisoning and I think I'll go pick up a poly filter to run just as a preventative measure. The symptoms sure seem to fit.

Also, I discovered that I was breaking a bunch of rules of copper; wasn't waiting for kalk mixture to settle before allowing ATO to pump it into the system, and was not considering copper sneaking in with alk and calc additive dosing (was only concerned with preventing large chemistry swings).
