Its a tank ... sort of

[pass1over]

My girlfriends parents house was completed awhile ago. In the back, they created 2 sections that will be a goldfish pond.
2 tiers, with tubing to pump water from lower back to upper section. Roughly 5 courses of block high on the tall one and 4 high on the lower one.

Her mom said she had found something to apply to the block to make the inside water-tight, but that she cant find it anymore.

Does anyone know of something that can be applied to the inside of these block "tanks" so they will hold water? ... I REALLY wanna see this part of the house get goin!!

Try searching aquaticeco.com for pond liner or something like that. There's your typical pool/pond liner that you could lay in, or there's some stuff you should be able to paint on, like a 2-part epoxy.

Marine stores might have something too. My brain isn't working right now.

Check the GARF website.... they have plans for a plywood tank, and they list the 2-part epoxy type paint by name and stuff. I can't recall it now either.

dry lock masonary paint will work to seal out best on fresh block.

Ha. My dad is the Midwest Sales Manager for UGL which is the company that makes Drylok. In fact, the license plate on my mom's car is DRYLOK. :p

are all these materials safe to be coating a container that will house live things?
I saw some of the links on aquaticeco.com about a couple of items.

thanks for all your help/ideas
