Hey fellas,
I discovered my calcium was too low (around 300-320), probably because for several months I used R/O water without supplementation. I just started with soft corals, but I need to fix this to expand into the hard coral species.
Therefore a month ago I switched to Red Sea salt, added a mineral additive, and started using a calcium solution on top. Plus I put a couple of dried cuttlefish skeletons in the tank to dissolve, on the recommendatiopn of the fish shop guy. But Ca is still 300. What gives?
My pH is a little low at 7.9, dKH is 10, salinity 30 ppt, ammonia and nitrite zero, nitrate 20, phosphates 0.5.
How are Ca, PO4, pH and dKH linked? Can i rapidly raise the calcium, or will this screw with my other water chemistry? Thanks
Shirley
