Acrylic/Plastic supply

[adamRS80]

I'm thinking of building a small aquarium/refurium/frag tank thing and was wondering where the best place in San Antonio would be to go get what I need. Also the tank should be around 30L*16W*16D...roughly 33 gallons of actual water without rock,sand whatever. What thickness of acrylic do I need? I don't know if I'm actually going to go through with it but I wanted to get an idea of where to go and what to buy.

for that size tank you need 3/8'' acrylic with 1'' trim around the top also in 3/8'' i built my refugium in 3/8'' and it's a 40 gal fug.it's doing great.

I'm interested in doing the same thing. BTW, would I be saving any money by buying acrylic/glass to build my own tank? Since I'm on a tiny budget, I figured I could make it cheaper than it would cost to buy one new or wait for someone to come around who needs to sell their tank cheaply...

Here's my suggestion, although Dan might disagree. Buy Spartech polycast or Cyro GP 3/8". If both of you are going to build tanks, you could split a sheet. Cut it with a 60 tooth triple chip grind carbide blade, or pay Dan to cut it for you, if he'll be nice enough to do it. You can use weldon #4, do not use weldon #3, to solvent weld. But, a far stronger joint would be with weldon #40, which is 2 part polimerizing cement. Unfortunately, that complicates your building a bit, because you have to rout shallow grooves, like "dado" grooves, to set the edge of the piece you're cementing in. At the least, if you solvent weld, you should leave a 1/4" overhang, then flushtrim with a router. Actually, if you can get your hands on a solvent called "M.C. bond" it's stronger than the weldon solvents.

In terms of saving money, it is cheaper to buy acrylic than a finished tank, but you could probably get Dan to make you a nice one at a reasonable price. The first sump/refugium that I made worked out okay for the few months that I had that set up. The test, though, is whether or not it will last years. Certainly the cheapest route is to buy a used glass aquarium that meets your needs. Cast 3/8" acrylic, Spartech or Cyro, is about $250 for a sheet at least. (I paid more than that for black.)

Of the local places, I think the service at Plastic Supply of San Antonio is the best. They do the best cutting IME. Good luck!
