Im new to this. I bought a forecloser home with a 16 by 32 foot, in ground vinyl pool. All the equipment is worn out from not being used in years. Im having the liner replaced but was thinking of installing new pump, filters, ect. My pool should have 21,100 gallons. Im wanting it to be cost maintence and low cost. The pump im looking at is hayward ecostar sp3400vsp. The filter is hayward swimclear 530sqft. Also was want to install the hayward pl-ps-16 prologic with sence and dispense and use the aql-chem3 for controling the ph. Im not sure if this is the right was to go. Are these pumps reliable and last. Is the filter large enough so I dont have to clean it every weekend. Is the automation helpful since wife works 3rd and i work 12 hours a day to keep the pool in balance most of the time. I want only have to check pool water every weekend if I can.
