dosing question

[TheGreenReefer]

when we dose something like gfo, chemiclean, or any other supplements/additives, should you dose for the size of your display tank or your whole system(sump and all)?

Yes total volume BRS calculator is a great place to find exactly how much you need

Your actual water volume of the sump and tank combined is best.

Keep in mind that rock and equipment displace water.

For example, my system is measured to hold 65 gallons but once I have sand, rock and equipment in, the actual water volume is only 45 gallons.

This is a calculator I have used to estimate total system volume:

Aquarium System Volume Calculator

It has inputs for rock and sand weight, as well as different tank sizes

Just a suggestion if your going to use gfo. Use half the amount BRS suggestions so you don’t strip out all the phosphate. Check the PO4 the next day and add more GFO if needed. You don’t want to stress the corals. IMO
