2 part dosing question?

[chris88]

on a consistant basis you should use both parts evenly. however if you salt is high in alk which most are then you woundn't need as much. Also if you are suing tap water you are getting some alk from it. Not all corals will take it up evenly but i always end up using the bottles at the same rate. I would do a one time dose to get them where you want them and then equal dosing to keep them there.
