Very nice looking build. I would also be interested in a price list. Thanks.

I'm glad to see a build like this. I've often contemplated using pond liner, but I was always concerned about sealing the glass or acrylic. Nice job!!!

looks great! i always though about making one of these but don't know what the life expectancy is on a GARF tank is. If you don't mind me asking, was it still expensive to build?

I am not sure of the actual lifespan, but I know of people who have working plywood tanks that are 20+ years old.

Here is a breakdown of the costs:

3 sheets of ¾” marine grade plywood $329.97
9’ of composite decking plank $22.41
¾” clear acrylic (90”x23”) $360.00
40 mil EPDM pond liner $153.00
16’ of 1 x 2 spruce lumber $16.56
Exterior wood varnish $41.00
2 boxes of 6 x 2” drywall screws $5.50
1 bottle of Titebond III $11.98
2 bottles of Loctite® Super Glue $12.70
Sandpaper $6.09
Finishing nails $1.50
3 tubes of silicone $13.35
Total $974.06

This total does not include taxes.

I got quotes for a glass tank and an acrylic tank of the same or similar dimensions. The glass tank was $1,800 - $2,000 and the acrylic tank was $3,100.

why didnt u go bigger i have a 350 and i carnt help but think its to small so over the next yr ill be building a gal steel framed 3000g plus a 1000 or 500 g sump

also whats the life on the black plastic?

LOL. I have no room to go bigger and I think I have pushed my husband to his limits.

The black plastic is actually synthetic rubber that is used in outdoor ponds. It has a 20 year manufacturers warranty.

I found a local plastics supplier that builds various acrylic containers. Their prices were better than the LFS.
