Which type of light do you have on that 20 gallon tank? Is it the
triphosphor lamp or the full spectrum lamp? I am curious because I am
wondering if tri-phosphor lamps are able to destabilize the chelator in
TMG. It sure appears to me that when I use triphosphor lamps I have to
constantly add trace elements way out of proportion to the light level.
I have noticed that other people have to add large amounts of trace with
those 96 watt fixtures. Maybe Roxanne is just not able to keep up with
the trace elements.
