I plan on keeping stingrays in this pond, so if anyone has any suggestions about how to keep the water temperature up (how to build your wood frame to insulate the tank and the filter) you should post! I also have no idea what kind of filter would be good for 480 gallon pond.

I want to use it for an eventual home for some motoro pups, maybe for retics and, for right now, a quarantine tank.

Materials that I have:
wood saw
2 1/2 inch nails x ~500
hammer

Materials that I know I need:
45 mm Liner (how big of a liner should I buy? Does anyone know a good place to order online? I would like to tuck the liner back over half of the lip, folding back down around the inside before I secure the wood. It has to look decent or I won't get the ok to build it.)

Filter What kind of filter would be best for a pond like this? I have been contemplating a simple sump / bucket system, fed by a pump, but the pond would look so much cooler if it didn't have a bucket hanging over it. I've never had a wet/dry filter, and I would like to use some sort of an overflow design with this pond. To have good water flow, should I draw from one long end and feed the water back in at the other?

Lumber/Wood What kind of wood is good for this? I am not a carpenter, and I am not sure of what would hold its structural integrity under the weight of 470 gallons of water. If anyone knows the names of the pieces (what I could literally just copy down onto a sheet of paper and then take to a hardware store employee) that I would need as far as wood and other bracing goes, I would be eternally grateful if you would post here or PM it to me.

Acrylic to build viewing windows As one of the things that will increase this plan's approval, I see these as essential. I will be building the viewing windows right into the side of the tank, as well as one into the lid. Does anyone know how to do this? Is there a way of sealing the tank or coating it with something other than a liner? Some sort of resin sealer, possibly? Can you easily cut and seal the liner? How thick does the acrylic have to be? Any experienced suggestions would be really appreciated.

Sealant of some kind When dealing with a project of this scale, is there a specific kind of silicon that can be purchased that is fish (and ray) safe? Should I instead use resin, or is something else a better material entirely?

Magnets I need magnets because this is how I plan on securing the lid.

Piping- I want to build jets on the output end of the filter to keep the substrate free from loose debris. I've seen a setup like this, and would love to find out how to build something like this. If I could get the tank to clean itself more efficiently, my energy could be spent on taking care of my rays in other good ways, like feeding them or building them a bigger tank!

Anyone have any suggestions? If you could supply me the names of the specific lumber, sealants/resins, and reccomended thickness/specific name of acrylic sheets, that would be absolutely awesome.
 
I wouldnt use nails. Internal pressure on the walls will eventually pull them out. Just like nails in steps. I would use deck screws for longevity and strength.

omg look at his avatar its a horse/zebra!!!!!!

it's a zorse lol

To the OP, have you looked at this company http://www.pondarmor.com/? Looks like it's a liquid pond liner. I don't have experience with this product but it looks like it would be a lot easier to attach an acrylic window to this than it would be to a real pond liner. Just something to think about...

45mm liner?!?
that's 1.8" thick...
you might want to use a 45mil liner...
45mil = .045" = 45/1000ths

Ha, that's what I meant. Nice catch! That would have been bad, trying to custom order that or something. :screwy:

filter use a pool pump and hide it in a fake rock :naughty:

A sand filter? Hiding it with rocks seems like a sweet idea! Thanks.
