My question is how much do you dose per day? I'm currently dosing about 290ml of Alk per day and I'm losing ground. My CA is also high...so I'm cutting back my dosing there.

Just thought I could get some examples of what other people have to put into the tank each day.
Hey Mark, your dosing doesn't sound unusually high to me. My old 90-gallon tank when it was setup SPS only I was pumping just under 125 mL per day into the tank and I had less than 100 gallons of actual water volume. I was using Fauna Marin sodium bicarbonate and I mixed it 125 grams per liter.
