    Okay thanks. I'll put those supplements on my list to buy. I made my RO/DI water today, so I should be good to go for a change tomorrow. And I do keep salinity at 1.025.

    could someone remind me what the equation for finding the total water volume of an aquarium is?

    Done in inches length x width x height = cubic inches

    gallons is cubic inches/231.

    also, I searched for the dosing calculator on here and couldn't find it....does anyone have a link, or can I just use one I find off Google? I'm trying to figure out how much of each supplement to buy off bulkreefsupply.

    Yes this is where it gets tricky. Do your measurements from the inside of the tank. Measure the height from the sand to your water line. Estimate what percent of the space is taken up by your rocks and subtract that from your total. No good way to calculate based on the weight of your rock. If you have a sump add the volume to your DT total.
