I finally took the next step and began testing above and beyond ammonia, nitrites, nitrates, and pH for calcium, carbonate hardness/alkalinity, magnesium, and phosphate. It looks like my carbonate hardness/alkalinity is high and my magnesium may be low.
pH: 8.2 - 8.4
Phosphate: 0 - .03 pm
Magnesium: 1125p pm
Ammonia: 0 ppm
Nitrate: ~15 ppm
Specific Gravity: 1.023 - 1.024
I began dosing the tank with CaribSea Purple Up a few weeks ago but have only done it sporadically. I have dosed with Seachem Reef Complete twice a half a week apart.
Does anyone have any recommendations for what I can do to improve my water parameters and can anyone suggest a dosing schedule for the Purple Up and Reef Complete? What are the ideal water parameters I should aim for? Will some combination of these two supplements be sufficient? These test kits and supplements were pricey so I would like to avoid purchasing anything else for the time being if possible.
