Hello, i have a working hot tub, but we do not use it enough to even bother. i was thinking in turning it into a koi pond. How would i go about it? everything works, heater, jets, pump. what do i do. to change it,, so it is save for the pond?
I see that you have not used a lining, which is what i would like to do, how did you seal off the jets, or did you leave it open?
I have a fibreglass tub, that I also want to convert. My tub is it's own stand, with all pipes and pumps hidden away inside.
What materials did you use to build the pond in your hot tub
