So, I am sitting in front of my tank last night.
Just watching life pass by.
I have a 75 gal
+ 20 gal
sump = 95 gal
I have 145# of LR
, so 1.933 lbs/gallon in the tank.
Now I know that water weighs 8.34#/gal
fresh and 8.6#/gal
for saltwater (depending on temperture, etc. but this is close enough for us).
I know the weight of the rock but the density varies so I cannot calculate how many gallons are taken up by the LR
SO now I guess I gotta unload a few big chunks and check how much space it takes up so that I can calculate the density SO I can estimate exactly how many gallons of water I have in the system. NOT 95 but How Many? One has to know!
Also I am wondering why I thought about this in the first place.
My head hurts . . .
