I have a 75g non-drilled, SPS reef and I cannot keep up with the calcium demands of the tank. I started out using 2 part solution, but had low cal and alk. I then switched to dosing baking soda and kalkwasser (Kent). Each supplement goes into a separate 1 gallon container.
Currently, I mix 1 teaspoon of baking soda with about 3/4 gallon of RODI and drip it in when the lights are off. I'm adding 4 teaspoons of kalkwasser in one gallon of RODI water, shake to mix, let sit for 6 hours and then drip in the clear fluid while the lights are on.
Both "dosers" are 1 gallon plastic water bottles. I use air-line and a control spout to pace the drip. The air-line in the kalk bottle is about 2 inches from the bottom.
Currently my alk is 8.2 and my calc is 270. Both levels are tested with Salifert test kits. My Mg is 870 tested using a Red Sea test kit and I have started dosing with Kent Tech M - 25ml per day. The Mg has dropped from 1300 from 3 months ago despite water changes an weekly dosing of Tech M.
I do weekly water changes of about 15 gallons, using aged SW made from IO salt mixed with RODI water.
Any feed-back would be appreciated.
