Having some trouble with maintaining a stable alkalinity in my tank. The alkalinity has measured 7 dkh on 4/9, 7.4 on 4/12 dkh and 7.1 dkh today. I have Red Sea Foundation B KH/ALKALINITY not sure what the correct dose would be and how often I should be dosing. I don't have a doser, so I'll be adding it directly into the tank. Here's where my parameters are today: Temp 81, Salinity 1.023, Ammonia 0.00, Nitrite 0.1, Nitrate 4.0, pH 8.0, Calcium 450, Magnesium 1400, Alkalinity 7.1 and Phosphate 0.04. I've read that the alkalinity should be between 9 and 10 dkh. I think that I should try to raise the alkalinity slowly until it reaches the 9 to 10 dkh level. thank you for your help.
