forgot to mention put the hollow TT in place before filling it
ours was 24x 24 and pretty heavy empty so depending on where in the
pond you put it
also we used multi colored lava rock the first go as it realy looked
perty when wet,,,,, in two weeks it was green. this I found out later
is a good sign its working properly
