Ok, started off with pmdd, dosing drops per day, but read that you need

adding up to 20ppm per day (per advice in this forum), and I can't keep
the
levels up. Fish start getting sick and dying, and I realize I'm
poisoning
them. Discontinue fertilzation, water changes, everybody revives,
getting
more algae now. The question is, if I can't add enough nitrates to keep
the
levels in the tank where they belong, is adding amounts that won't hurt
fish
going to help anything at this seemingly high rate of consumption. Also,
if
the plants were really consuming that much, what was hurting the fish?
The
high levels for a few hours til the plants took it up, or some kind of
byproduct? Thanks! Allison


Check your test kit. Had a bad one a few months ago and it darn near
got me into a lot trouble (NO3). Compare your results against a known
standard. Seachem has a test sample in their kits. You may want to
look at PO4, Fe etc. to see if they are in balance or within range.

good luck.

I have been meaning to do that. I should try the seachem.
Thanks!
