what is the name of the filtering system, where to purchase, when refilling a swimming
pool after marcite job?

the purpose of the filter is just one use, to remove all trace minerals from tap
water, it reduces need for chemical balancing as water will be cleaner for the full
fillup of about 15,000 gallons

can one purchase this from a pool store online, water quality or equipment maker?

something that I can attach to end of garden hose and let the pool fill up overnight.

thanks.
