Display = 25g
"Bastard" Frag Tank = 65g
Well I tried to mentally add in the volume of rock a 180g + 55g sump minimal rock, sump about 75% full, plus big skimmer that adds another gallon or two to the mix, 10g frag tank hooked up (although I'm going to take it down soon), 80g tank + 30g sump.. so I figure 41g of live rock from my 300g estimate? I don't think I have that much in rock volume.
Good thing I have a spreadsheet for this :lol:
I have a 20 gal right now but I'm eating a lot of ramen noodles and saving my pennies for a 75 gal with a stand.
I'm trying to see which page people couldn't count past.... I give up. Smart idea that spread sheet was. That's what I call quick thinking. H)
Do we have a number to beat yet, or is CO. still counting too?
Quality not quantity
i lost track too where it ended but here goes
frag tank = 180g
frag tank =180g
tank 3 & 4 share sump =100g
grand total =667 gallons
65 Gallon Display
Water Change Tank 900g
Is there a rule of thumb on how to estimate actual tank water volume?
Display = 180
sump/ refug = 40
frag tank = 20
how close are we to the volume of the Academy of Sciences reef tank?
LOL CookieJar... I think we have enough water to fill up one of their skimmer LOL ..
display is 240 g
sump is 125 g
which totals 365 but with my rocks its about 300g
For a normal tank:
T= thickness of glass/acrylic in inches
D= water level drop below top edge of tank
H= outside height dimension of tank
W= outside width dimension of tank
L= outside dimension of tank
R= lbs of live rock and live sand
overflow: highly variable depending on type and numberr (guestimate it)
Volume in gallons = ((W-2T)*(L-2T)*(H-2T-D))/231 - R/23 - overflow
So..my "40g tank" has 3/8" acrylic, measures 36x15x16H, has no overflow, water level 1" below the top and about 25lb of rock and no sand
((36-2*0.375)*(15-2*0.375-1)*(16-2*0.375))/231 - 25/23 - 0 = 30 gallons
(you can just cut and paste the formula into google and replace the letters with appropriate numbers like so
Gresham, update me for 30 and 11
100 display + 30 sump + 210 display + 60 sump + 20 refug = 420g
Thanks Tony - Thanks Nanoguy,
This has been a long standing question for me, and am so glad to finally see the formula laid out.
130 gal total for me.
display - 220
sump - 40
frag - 40
about 100 gallons total water volume
~300 for me!
