Ok so I have bought this 210gal with 180gal sump. I have filled it add 200lbs of dead rock. It has been going for 3 weeks now and the ammonia is at 0. Nitrite levels still 1.6. Question is when I moved my 140 into the 180 sump, I was able to use all of the water, sand and live rock 200+ lbs. Will this be enough to filter out remainder of the nitrite in the top tank? I have a few softies in the lower tank, along with some zoas and mushrooms. I dont want to kill anything, but I want to get these two tanks running togther. Will these levels hurt my frogspawns? Zoas? GTBA?
