Solar hot tub heater, that kinda works

Building a DIY solar water heater for my hot tub. I have very mixed feelings on this project. I spent about $180 (excluding the pump) on building this. It paid for it's self in one summer, but it was a PIA the whole time and it is not very likely to survive another summer.

Does it work? yes, sort of. 

Is it worth it? no not unless you all ready have all the material laying around and you have the free time.

Would I build it again? only if other options were not available or space requirements meant there were no viable options (I would select better materials).
