Ca, Mg and Alk Help

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.

 

Okay, thanks Steve. That's what I will do.

 

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

 

type in

"x square in to gallons" in google ;D thats what i do

 

hahaha thanks.

 

Done in inches length x width x height = cubic inches

gallons is cubic inches/231.

 

Do I have to subtract anything for sand and rocks?

 

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.

 

Oh my, okay I'll try lol.
