how would you go about heating and filtraing something this big and how much would it cost?
You can check out both among the posts listed below. At present using AquaOne bead filters on both 15,000 and 52,000. Rinai tankless gas fired hot water heater with 300' pex heat exchanger. Costs vary but the worst months for all the tanks runs $1,200 for heat and $1,200 for hydro.
