When you calculate how much to dose do you include the water volume in your sump as well as your DT.

(DT water volume + sump water volume - rock displacement) / 2

FYI
every-time i followed the bottle instructions i always got problems so i just do half of what it says.

Ok I cant wrap my brain around how to calculate rock displacement.Why do you divide by 2?

well looking at your signature if you got decent amount of live rock id say you are around 140g? if that sump is half full.

My sump volume is 65 gal + 165 gal DT = total water volume is 230 gal. But not 100% sure how many lbs of rock is in the tank and sump. When I re-do my rock work soon I should weight it all, will that help to determine the displacement?

Yes but how much water do you actually have? Most sumps run around half full I would guess so call yours 35 or so? Then in your display there is probably only ~140 gallons of water after you subtract rock displacement etc. So I would base your dosing, Zeo or otherwise on ~175 g system and not a 230g system.

And I agree with Milad, start with half doses for zeo.

This calculator might help, it allows you to enter the weight of your LR and LS to help determine water volume.

Cool this will help once I figure out how much rock will be in the tank and sump when redone.

[The Grizz]

The sump running is 65 gal, I have calculated the volume of all chambers individually to get that. The sump full of water is 80 gal. When I filled the tank before rock it was 165 gal before it started to spill into the sump and with the rock I would guess it would displace 25 gals.

spend some time on the zeo site and do your reading!! Its well worth it. I was dosing wrong for quite awhile and it led to nothing but troubles.
