Well I originally purchase a swimming pool. Cost me around 70 dollars. It is 6 foot across and 4 foot deep. Its for keeping fish not swimming :lol: Well, How many gallons do u think that it holds? I dont wanna measure adn it seems to be alot..... Could i get some hints? :blink:

Is it... Circular?

Is the pond rectangular? if so you could use LengthXWidthXHeight Divided by 231 =How many gallons.

The pond is a cricle.

about 576 gallons, based on a the cubic square footage.
6*6= 36, 36*4= 144, 144*4= 576
if I am wrong Please let me know! this is the cubics to gallons, and not cylindrical. lesser for that, so I would guess about 500G :up: :down: ?

Wow. Thats alot of water. I'll try to post a pix when i got it up and running. I might even put a very big fish in there:P Thanks for finding it for me. I owe u one :P :up:

I didn't find it. I am a carpenter by trade. btw... pics would be great, use black as a drop plastic or and half sun/shade, reduces on algae. Trust me!

I get 814.3 plus or minus .1

But I didn't do the math myself... I just plugged it in to another site with a volume calculator for cylinders...

where did you come up with that one? To be to the exact measurement... 452.38923G if one square foot equals exactly 4 G of water.

SM, I think you went by the calculations of 6 by 6 and not 6 by 4...?

oops my bad, guess 7.4 gallons to the cubic foot, son and the hubby did it the old fashioned way. milk crate and the milk jug by the oz... lol :o 836.92G

Where is that site for the volume? son wants to know, and he also wants to know where you came up with 7.2G per cubic foot?

Cool. I'll do it then.

It's HERE


I put in 36, 0, 48, then divided the result (total cubic inches) by 2400 (the total cubic inches in a 10g tank), and multiplied by 10 (since I divided by the amt. in a 10g tank).

I did:

6foot x 3.14159265 (pi) x 4 = square footage
Convert to US gallons: 564 gallons.

:unsure:

I don't remember a whole lot from geometry, but I think it's RxRx(pi)xH Or: 3x3x3.14x4 which gives 113.04 cubic feet. I don't know the conversion rate for cubic feet, but it's 240 cubic inches per g... so convert 113.04 to inches by multiplying 113.04x12x12x12, then divide by 240... I get 813.88 (discrepency due to not using completely accurate pi figure)

Okay, found this calculatar:

113.097 square feet = 846.024 gallons (US)

Well one thing is for sure, it's somewhere between 500 and 850 gallons. :D

i will do it in metric form and then change to gallons for you just a second

Volume of a cylinder=pi x r^2 x H
=pi x 90cm^2 x 60cm
=pi x 0.9m^2 x 0.6m
=1.52681403m^3
m^3 --> L = x1000
=1.52681403m^3x1000
=1526.81403L
L*.26425=USG
=1526.81403L x 0.26425
=403.4606073 gallons

LOL. Math class.com. AquaTopiaMath

OK. So now that we know that his new pond is between 50 and 5,000 gallons.. lets get some stocking ideas! :D

Yeah, we figured it to be about 7.4 gallons per cubic foot. Hubby and son found a fancy calculator on the net too. They even got the calcs for my odd shaped pond. lol... now I just want it to be filled!!

Wow thanks. I found the original gallon. It's 3,750. WOW! :lol: The price was $420. I didnt buy it yet. Is it a good deal. The real dimnsions are, 15 foot long, 9 foot wide, and 42 inches deep. This is a really amazing pond or pool. It comes with a pool filteration too. Do u think its a good ieal to use that? If 420 is a good deal then I'll save some money to buy it!!! :D :up: :$:

I'm not sure how pool filtration works. Do you have a diagram (or make one. ;)) of the mechanism? Then I (and the rest of us) can let you know. :)

sounds good either way even if u have to get filtration another way that is massive

It kinda looks like that.

I could probably keep 10 aro in it :P :lol:

I even went to the website you've hot linked from, and I can't work that one out... :unsure: I can't even work out which direction the water goes!

Looks to me like it's just a physical filter... which won't do much for the fish, but will make your water nice and clear.

Not sure what kind of bio-filtration you'll need, that would depend on your stocking plans.

Maybe you could look into a way of changing that filter so as it does biological filtration. I am not sure how I personally don't understand a great deal about filtration probably something that i should look in to.

If I understood the filter I'd offer suggestions! :P

wow!!! that's a lotta water!! :o

I did some thinking and said im not buying it anymore. The water bills are going to stack up if i buy it :P
