I have a pond question. I would like to incorporate an in ground pond as my fish tank. I currently have a 275 IBC setup but would like to expand to a larger in ground fish tank. Something in the neighborhood of 10'x6' by 4-3 ft deep. This would be about 1800-1350 gallons. My question is what is a suitable liner materiel (ie. rubber, poly)? What is the rule of thumb for grew bed size per gallon of water? Also, most pond builds i see on youtube use mortar to hold the rocks in place. Is mortar okay to use around edible fish? TIA
Paul D. Ulici there are liners, EPDM works, so does the DURASKRIM stuff. HOWEVER, the big problem with this bigger size tank you're thinking of, is the fact that any liner at that size is going to be very expensive. You can find long liners cheap, but wide ones are not cheap.
Concrete is fine for a pond, and the fish would be most likely ok. The main problem is that concrete will keep raising your PH unless you coat it with something. Some people have used Thoroseal.
Personally I've thought of creating a larger tank, and if you're going to make something that is lined (out of concrete) I think a good option is to make it narrower and longer, so you don't need a really wide liner. You can find 10 foot wide liners much cheaper than anything wider.
I like those tanks someone posted not long ago that were made out of plastic sheeting or whatever that was. no need for a liner, and quite big.

Chris Magree i ordered my liner from webb's online...firestone (20' x 20' liner, $250.)
Chris Magree it's just raised 8" (cement blocks, concrete, rebar) so i could have a shelf around the edges for plants ... so i still dug down at least 3' (probably more) but the sides got built up as i was digging down...so that helped...but if you do that make sure you compress the loose soil before you build on the edges....
