Oh ok, it's being fiberglassed. I was under the impression that it was going to remain brick/concrete. I have koi, too.Originally Posted by nick3d
Errrm well...
We are having the concrete poured in next saturday, then we are building the walls up from the concrete, then we are having it fibreglassed. so does that answer your questions lol

And plus they are japanese koi carp which are decorative
Fiberglass or pond liner are good. I would favor pond liner over fiberglass, though... Fiberglass resin actually takes years to fully cure. Laying some sand on top of the concrete before laying pond liner is the most desirable thing in this scenario, but would be a pain in the ass if it were to tear.
