I have a 75gal FO with 80lbs of live sand, 50lbs of live rock,2 aquaclear 500s. One with foam insert and a bag of BIO cubes, the other with foam and charcoal. Also 2 titanium heaters running at 78degrees, and I use RO water.
How long till the cycle is over? The nitrites are way up. How long till they drop? What else can I do to help?
