Hey ** Pro's, looking for some help dialing in some dosing/feeding and with Nitrate control. Here is an overview of whats in the tank, parameters and products that I have available currently. Tank is a 75 gallon with 25 gallon sump. Running an oversized skimmer (vertex 150) and a reactor with ** Carbon and ** GFO. Water changes are consistantly done and have been large to keep Nitrates down. Current Parameters (using Red Sea Kits) ALK 7.6 (aiming for 8) Cal 420 MG 1400 Nitrate 12ppm SG 1.025 Temp 79 I am currently using my old two part to dose ALK and Cal until I mix up/make my new components using the established formula.

Every other day I add a sheet of nori for the tangs and ever now and then i add a few pellets for variety. Beyond my current two part dosing with the tank being on the new side and a low coral load I am thinking of a schedule like below for coral feeding. Sunday - Monday - ** PowerFood/** Ricco 1/4 Dose Tuesday - Water Change / BioS Wednesday - Thursday - ** Energy/** Build 1/4 Dose Friday - Saturday - ** Vitality/** Amino 1/4 Dose Ocassional dose of Reef Roids and Pellet coral feeding not exceding once in the week Now given all that can anyone see why nitrates may be high and or would any of the above dosing cause an issue such as high nitrates. Look forward to hearing your thoughts.
