For water changes, I find it much easier to try to predetermine the amount to use, instead of mixing and adding and measuring. It says a box is 200 gallons, a box has 4 bags, so a bag should be 50 gallons. The problem is that is not enough salt for a reef.
Looking at the instructions, it says "1.5 lbs of Instant Ocean is formulated to create 5 gallons of saltwater at a specific gravity of 1.022". I generally don't weigh salt, the bag weighs something, and moisture content varies, especially if the bag is open. But I assume that 1.022 is their target for 200 gallons per box.
Am I correct to then assume that 1 bag is good for 50*.022/.026 or 42.3 gallons? Or can't I do the math that way?
