However, there is an alternative. Many people recommend that you just monitor
the growth of your plants...particularly the fast-growing plants like frogbit

That's what I'll do. My *&(#$& iron test kit does not work at all, and that
caused me to OD on Fluorish Iron the other day. Water had a weird yellow tint
for a couple of days. Fish are ok though... spawnign and all...
