Prazipro Dosage

[Shluffer]

Apologies if this is already somewhere else. I did a search, but possibly not well enough.

I have a relatively large tank. I need to figure out my dosage, and I'm not really sure how to offset the space for rock from the total water volume without pulling all my rock out of the tank (which I"m willing to do if I have to, but I'm worried about disrupting the tank).

How accurate does dosage need to be? any ideas on how to estimate the displacement without removing rocks? I can guess .....

That does help. Now I have to remember now much rock I have. Sigh
