Calculating Pond Size (Need MORE help!)

[happyhillbilly]

EDIT: I'm cutting some of the liner to make a waterfall. Then FINAL size (hopefully) is 13x17. Sorry, I have a lot of trouble in math, I'd rather have someone experienced do it than screwing up my pond.

I am thinking maybe 5x 16 or so.

5x16 is roughly 800-1000 gallons or so.

Lenth X Depth X 2 then you need a border of 1 foot on each side

So for example you could have a pond that was 3' deep with dimensions of 5' x 12. With the depth part of the calcuation, all that matters is max depth.

 

[zacdl]

yep. 3 feet times two=6 plus 2' extra=8 then the extra left on that side is the length (5')

I did the same on the other side.

 

[happyhillbilly]

Sorry, What do you mean by 5x16?

 

[RogerMcAllen]

He did roughly the same calucations as I did, and they are feet. Using my equation and the max depth you want, you can figure out how long/wide your pond can be.

 

[happyhillbilly]

No, I mean what does 5 ftmean and what does 16 ft mean? Sorry, I'm just realy tired and out of it.

 

[happyhillbilly]

I think i get it. The length is 16 and the width is 5, right?

 

[zacdl]

Yes, the finish pond area (The surface area on your lawn) it will take up will be around 5x16 feet.

Ok, lol, I'm soooo slow sometimes. I have another quick question. I was wondering about this filter box (http://www.lowes.com/lowes/lkn?action=productDetail&productId=60024-45001-MF500&lpage=none) do I just somehow put a pump like this (http://www.lowes.com/lowes/lkn?action=productDetail&productId=59086-45001-PP675&lpage=none) to it and then have a tube up to my waterfall? Or do I have to get 2 seperate pumps?

 

[zacdl]

Either way you want it.

If you just want something in the bottom of the pond to circulate water and have a seperate one for the waterfall that would be fine.

I would stick the pump in the pond and have tubing going up to the waterfall.

Get a Laguna Powerjet, they are extreemly energy friendly and cost not a lot to run (Cheaper than the one you were planning on)

www.drsfostersmith.com to get those.

 

[RogerMcAllen]

That filter is exactly what I had on my small pond. ~4'x8'x2'. That would be good for a small pond, or perhaps for a small waterfall (mine only powered the equivolent of two small spitters). I would suggest a larger pump, and perhaps even a canister filter. Check out the reviews section (there is a link at the top of the page) to see the ones I have. Pumps and filtration is not my strong suit, so I would wait until AFF and CC show up with some better advice than I can give.

 

[zacdl]

FishMates UV,Bio unit is a good filter, about $110 or so.

Some handy calculators:

I think the formular is get the cubed footage of the pond and times it by 7.1 (7.something it might be a little higher but I think it is 7.1)

 

[happyhillbilly]

Thanks a lot guys.

 

[happyhillbilly]

'bump' look at my first post

 

[RogerMcAllen]

I have forgotten, what are your original dimensions.

 

[ReefNooB]

the formula to get your pond liner is

Pond Width + (Pond Depth x2) + 1 foot (for edging) + 1 foot extra = Liner Width
Pond Length + (Pond Depth x2) + 1 foot (for edging) + 1 foot extra = Liner Length

and the formula for pond volume is

Pond Length x Pond Width x Pond Depth x 7.5 = Pong Volume

that is for a rectangle for a circle your replace the 7.5 with 5.9 in the above formula

 

[happyhillbilly]

The origional dimensions are 5X12. Sorry ReefNoob, I don't realy get what your saying.
