I checked out the new lighting at the zoo today. HUGE difference! It looks much brighter and sharper with much better color saturation in the corals. Colors are popping now whereas before they were very muted. Paul did a terrific job redoing the system.
Today I tested all water parameters and thjey all look decent.
dkh - 12, ca - 380, mg - 1280, ph - 8.4, NO3 - 5-10ppm, salinity, 1.026, PO4 - 0 - trace. If I can, tomorrow I will bring in a couple of sps frags for a test. If that fails then we have to consider that there may be a problem with our DIY rock. Thus we may have to substitute out some DIY for some Fiji. Larrybird is willing to trade some of his LR for our former t-5 lamps. I also have some pieces I could donate. I'd also like to test for copper if anyone has a kit lying around. Maybe some of the rock I purchased was contaminasted by copper treatments.
