I have been using Ocean's blend two part system since I started my tank. In the mid of the second year they changed formulas and made it stronger. I have began adding it again after trial and error on the strength of the new formula. My calcium ranges between 420-440 and my alk is consistantly 6.2-6.3. I have been adding 3 ml of each per day in my 90 gallon. I assume you should be adding equal parts of these, would I risk throwing off the balance if I started adding 4 or 5 ML of alk and keep 3 ML of Calcium to get the alk up a bit? If so would adding additional Calcium with Alk potentially put my calcium to high along with bringing my alk up? All other parameters are perfect range, RO/DI 25% water changes every month...Tank is not completely packed but probably 20-25 corals, Thanks
