We maintain parameters via combination of calcium reactors and dosing bulk additives for the ‘major three’. We find that there are benefits to both methods; Ca reactors for the consistent addition of balanced elements and dosing for its fine tun-ability. Breaking down reactor media also helps add Po4 to the system. No3 and Po4 are tested weekly. Protein skimmers are often turned off, sometimes for weeks at a time, to maintain sufficient nutrient levels. Feeding daily with a variety of good quality frozen foods also helps play an important role. It is important to keep in mind that every system is very different in terms of its nutrient uptake, so what works for one system, my not be right for another.

SPS System: calcium 440, alkalinity 8-8.5, magnesium 1350, salinity 1.025, Po4 .03-07, No3 5-10
LPS System: calcium 430, alkalinity 8-8.5, magnesium 1350, salinity 1.025, Po4 .05-.1, No3 10-15
