Seems like I should know this already but the more I think about it, I'd like confirmation - how should I calculate tank volume for calculating various doses?
So I have the RedSea Reefer 625, which is listed as 131 gallons of the display tank, and 32 gallons in the sump, and then I have about 100 lbs of MarcoRock between the display and some in the sump, and then 3 MarinePure Blocks too, and of course equipment.
Some say the tank manufacturers inflate their listed tank volume because they use outside dimensions instead of internal, and I know MarcoRock is dense and heavy, so maybe displaces more water than others or live rock, but then the MarinePure Blocks are super porous and probably don't displace much water at all.
A volume estimator tool I found says all that rock, blocks, and even sand only takes away about 10 gallons of water from the total volume, but that doesn't sound like much.
So... thoughts?
