32G Brute - 22" x 27-1/4"

0.85 gallons in an inch (around that)

take 27.25 / 32 = 0.85 gallons per inch

it is not exact, but its close, but if you wanted to get technical, you need those other dimensions...
and the fact that the can is slightly tapered....difficult calculation to be exact.

You can calculate the volume of a cone and then subtract the cylindar from it's center but you already know the volume of the can so that doesn't help.
Unfortunately the most accurate way to do this is to get a 5 gallon bucket (one that you know is 5 gallons) and fill it and dump it into the 32g Brute. Marking it at each bucket full. That will give you marks at 5 gallon intravals. It should take almost 6 1/2 time to get it full. What a lame way to measure something.

Reverse engineering at it's finest LOL.

Wouldn't it be easiest to dump 5 gallon buckets of water in one at a time and mark the water level each time? Seems like a lot less math to me.

--edited after coffee--
I guess I shoulda read the post above me a little more completely.

When my engineer husband gets the math done I will share it with all of you.

Weighing the can would work great if I had scales big enough to balance the can on and still be able to see the numbers. My bathroom scales won't work as the can would completely cover them and I wouldn't be able to see the weight. That was another one of those "Duh" moments. :)

Lol, Trish. Just got my power head, heater, and remaining salt (which wasn't quite enough) into my 32 just tonight ;)

You and I seem to be on similar paths.

Do you also have a 20 gallon Brute for RO drinking water? A "yes" on that would be eerie.
Yea I have a 32 gallon for salt mixing and 20 gallon for top-off water.

My question to Trish is Why????

Why do you have a 32 gallon container but only want to fill 10 inches?????

By Nate's rough calculation that would be around 8.25 gallons. Depending on your water change needs the big rubbermaid may be overkill. I need the 32 gallons to do the biweekly water changes for my 90 and 125 gallon tanks. If you only need around ten gallons of water then 1-2 old salt buckets with maxijets for mixing may be a more cost effective and space saving alternative.

JMHO

I completely forgot about this. We are going to measure now.

The reason I am using such a big container is that Lowes didn't have a smaller Brute in stock. Plus I am changing out sand for Seaflor special grade and I am going thru the water siphoning sand. I will need about 20 gals per week to do 15% water changes.

Ok, here's the verdict. This takes into effect the transition at the handles but not the raised part on the bottom or the indention of the handles.

Inches = gallons
1 = 0.57
2= 1.65
3 = 2.73
4 = 3.83
5 = 4.93
6 = 6.05
7 = 7.17
8 = 8.30
9 = 9.44
10 = 10.59
11 = 11.74
12 = 12.91
13 = 14.08
14 = 15.27
15 = 16.46
16 = 17.66
17 = 18.87
18 = 20.09
19 = 21.32
20 = 22.56
21 = 23.80
22 = 25.23
23 = 26.66
24 = 28.09
25 = 29.52
26 = 30.05
27 = 32.38

Oh come on!

It dose not take into effect the raised part on the bottom or the indention of the handles?

why even bother then......


Just kidding! I'm sure those numbers will come in handy for some people, my question is what are you mixing that you need to be that precise? makes me feel bad, I just grab a bucket, dump water, then throw some salt in, you are getting all scientific here on us :p
