    Just hooked up my bubble magus dosing pump and I'm going to be using BRS 2 part. I was able to find directions on here as far as programming/priming pump/timer and what not but couldn't find anything about quantities of what to add to use as a reference point. I know all systems are different but wasn't sure where to start. Total water volume is approx 65 gallons. I started alk and ca both at 100ml per day and mag at 10ml per day. Tank is mostly lps, 4-5 small sps frags and a 5" crocea. I'm going to be testing all 3 daily to check progress and try to tweak it to I get to where I'm happy.... My goal is to shoot for 10 alk 450 ca and 1400 mag once I get it dialed in. Any feedback is appreciated.

    I can give you a comparison on what works for me. I have about 40 gallons total, about the same with the Clam and hard corals. I've been dosing 4 ml Ca and 16 ml alk/ day with BRS 2 part. I add 5 ml Mg/week with water changes. This formula worked for about a month to keep Ca at 420+/- and alk at about 10. Recently Ca dropped to as low as 350 (past few days). I've increased Ca to 10ml/day and kept alk the same. Ca climbed back to the high 300's. Also there is a calculator on BRS to raise levels up and their estimate as to a starting point for dosing.

    What i would do is doing some testing and see how much ur ca and alk drop in a week. I would then decide how much to dose. I have a good amount of corals and inly add 50 ml.

    Bingo. That helped me too.
    For another reference on my 26 gallon I have found that 24 mL/day for both is great for me most of the time. Currently though my calcium runs a bit high at 500 so I am cutting that one back a bit. My alk tested out today at 3.8 meq/L. I won't touch that. (I try to keep magnesium at 1400 - currently under 1350. Dosing just 1 mL/day through my Bubble Magus.)

    That makes me think your 100 mL/day for a 65 is a bit high.
    I'd be curious to know.
