ive considedered crabs as the culprit but i think they are innocent. its when the fish are weak and ill and dying then the crabs pounce in.
i was thinking i may have too much of a circulation perhaps? i have a closed loop powered by a mag24 with a SCWD. i do have micro bubbles coming out of the loop. been trying to eliminate it. last recourse for me is too ditch pvc
and change to vinyl tubing perhaps.
also, dunno if anyone can address this question but, am i supposed to have agressive water circulation with a FOWLR
setup which is what i have or is the return from my sump (mag 12) and the return from my FLUVAL 5 enough?
reason i am asking is because i think my pets are happier with just RETURNS from my sump and fluval 5. water is clearer too without the micro bubles that my closed loop is producing.
