i havent been on here in a while now.. sorry on the updated pics.. ill try and get some up soon...
Something in the build is killing off the fish.. Everything was suppose to be fish safe... I used beckets pond foam, super glue, a plumbers epoxy that was safe for potable water which means its safe for fish. fiberglass resign which is safe once curred..
And than the egg crate, coral skeletons and crushed coral.. Dont know whats killing off fish in the tank but ive been meaning to flush the tank many times and get a good amount of carbon in there and see how it does with some guppies..
