Ryan,
Must have been posting at the same time as you.
Interesting words on the filtration system. The way my operation is set up, the spa filter/pump runs only when the heater element comes on, which is fairly infrequent right now, but will be more frequent when I crank up the temps later on. The aux filtration system actually runs constantly 24/7. I'll look at routing it through the spa filtration but since the spa filter/pump only runs when the heater element kicks on, seems like that is not practical in my case. The aux system cycles a volume of water equivilant to the spa tank every 45 minutes. A similar system has performed very well in an outside micro-pond stocked with fish, including Tilapia It's capacity(the rated cap. of the aux system) considerably exceeds the size of the spa...750 gallon spa vs 2000 gallon aux filtration system.
Would you say a spa used in this manner could never be used for human purposes again? I'm actually hoping that is the case and will make this a permanent arrangement.
