Hi guys need a bit of help from you chemistry wizards I have my calcium back up to 460 ,I tested after 3 days to see how much the tank was using and the result was 20 parts drop per day now I wish to dose a stock solution of 5ltr ro .water with seachems reef advantage calcium to cover my 500ltr system but now for the big question how much of the reef advantage calcium would I have to add to the 5ltr ro to keep my calcium balanced at 460 if the tank is using 20 parts per day. Now I'm starting to confuse myself lol so I hope some one out there understands what I'm trying to do and can help me out thanks
