So about 4-6 months ago I switched my sand from normal argonite sand to black petco brand sand but put the other sand in a chamber in my sump for DSB benefits. About a month after that I got an led light off of amazon and bleached a few corals along with a nem, but since then any new corals (xenia, kenya tree, now seems to be hitting my torch) also seem to die even with the light set at about 25% power on both my blue and whites LEDs. My PH is a little low at about 8.0 but remains stable, my ammo and trites are 0 trates at about 5 constantly. Temp. 80 Salinity. 1.025 Cal 450mg/l. I've recently noticed that my black sand has a tendency to stick to the magnets on my algae magnet, leading me to believe that it is partly metallic and possibly leaching heavy metals in to my tank slowly? Does this sound possible or am I just talking crazy?
