Currently my pool and spa are connected in the same filtration/pump setup. I have a pool heater (400,000 BTU propane) that heats everything. The spa has its own plumbing that is easily separated from the pool.
My main questions are sizing and filters.
The spa is ~750 gallons. What size pump should I go with? Also, I need an idea of filter size and type. Should I go DE?
Any idea of heater size and type? As stated before, I have a 400,000 BTU unit that was intended to heat everything, might not be a good idea to use. Not to mention it's 20 years old.
Thanks for any help!
