[hi, i have a 29 gal tank that has established for 2 months now. all parameters are great, except it is a bit cloudy. i think it might be because of micro bubbles from the sump, but i don't know how to prevent this. i have baffles and a fuge. it could also be from the new seio 820 i installed that blew a lot the detritus off of the rocks. how long should it take for the tank to clear up? thanks]
