Thanks gregzz4 and reefwars I appreciate all of your help. like I said I'm just little nervous starting something new. :smile:

Good luck and keep us posted

I too was hesitant when I started 2-part, but it's all good

Nope it's not ,if your part a is soda ash you could be dosing as much as 150 if demand is high 60ml is a decent starting point but I would raise it to what you like first with manual dose then set your doser;)

I dose 40ml in a 40g tank and 175 ml in a 200g zoanthid system:)

And your dkh is dropping .87 dkh per day if you take Account your 25mls dosed. Use a reef calculator to help find a starting point if you need to:)

Ok update time, Im dosing 35ml Alk, and 50ml Ca and my numbers are stable. Alk ~8-8.3, Ca 420, Mg 1320. Sps is doing fine growing well. Is it normal to have such difference between the Alk and Ca when dosing, I'm guessing that 15ml is not really a significant difference?

Good to hear your params are stable Randall. Let's see some of those pieces now! :lol:
