I have some other lights around and have tried them. I have a vho and two
pc ballasts. Each time i have tried a nother light source the calurpa
starts to be choked out by some type of hair or slime algae. I have tried
new bulbs, different spectrums, and different wattage (no 20w vho 55w and pc
95w) all with the same results within 1 or 2 days. The strangest thing is
that I don't have algae anywhere else in the tank. As for substrate I have a
powdering of very fine argonite that came from my main tank and a 5 or 6
small pieces of rock that did not do anything but fill opening my main tank.
