I like dendros and sun coral. My wife really likes them also. Mostly for that reason i think i would might go with one of those or the like. Actually, things in my tank just got kinda odd. After moving a small amount of sand from the fug (which has a dsb actually, now that i think about it) i am having low ph issues. Last night it got down to 7.6 with alk at 150 ppm, calc at 425 ppm, and mag at 1450 ppm. The real weird thing is that i literally cant get the alk to raise at all. I use brs 2 part, and just cant get it to move at all. I wonder if there is a bacterial bloom occuring. I just realized that i disturbed the fug dsb and that surely was stupid. Ive never done the dsb thing till now and it wasnt intentional. Any thoughts? It seems that i sbould wait till stability isnt a problem to thing about adding things. Thanks very much guys.
