I'm new to the hobby and have a 5 month old saltwater 110g tank, with sump and sock filter. Currently in the tank, 44lbs live rock, 8 small Fish, 6 Inverts, 4 plants and 4 soft corals. The water tests over the past 2 months have stabilized and are consistently 1.026 salt, 8 PH, 0 Ammonia & Nitrite, 10 Nitrate, 420 Calcium, .25 Phosphate, 9 KH (API Test Kit). Do I need to raise or lower any of the test? and with what additives or reactors, etc.?
