    From what I have learned if the hypertufa was not cured correctly it could be toxic to fish.

    The cement has a high level of lime which is quite likely toxic.

    I found this how to make Hypertufa the lady talks about curing.... years ago my dad and I built my first fish pond, out of cement... after a couple of days or so I filled it up with water and put fish in it... almost immediately the fish were acting strange, and a film started covering their bodies and sloughing off of them... I caught 2 of them took them to the fish store, and the man told me it was the cememt, it hadnt cured properly and it was taking the natural slime coating off the fish... Luckily he knew a solution and had some Neutralizer blocks to add to the water which fixed the problem... So from what I see about Hypertufa It needs to be cured completely before being introduced into fish water.. If its an older pot that has had plenty of time to cure it should be ok.https://www.youtube.com/watch?v=5gUlLQBoiP4
