I use the reef keeper for the controller for the tank. Got two dosing pumps from Bulk and the 2 part Alk
and cal with meg. Mix it your self, makes a gal
each, 20 oz of meg. Set the Multi timer so Alk
is 12 times a day starts at 12am and every 2 hr. cal 11 times and starts at 1am. Small doses all day, I do the meg 3 times a week, need to get another pump. I still do a WC
every week 25 gals for the other stuff. I have a 310 gal
two sumps,total water is about 350 with 280 lbs of live rock. Trying SPS
The reef keeper will pay for its self.
