50G Reef Tank with Natural ocean water, sand and rocks - June
This is from beginning of June. RO/DI filters were changed, TDS is back to 0 now. I had to start dosing 6g of baked baking soda and 40g of Calcium Chloride every 2 weeks to maintain PH, Alkanity and Calcium. Nitrates are down to 1. Everything seems healthy.
