I'd be screwed without this Forum. Love it, fantastic source of invaluable information. Keep up the great work!
I have an Intex Ultra Frame Pool, 18 x 9 x 52"D, ~4560 gallons. The pool meets the needs for the grandkids but as you likely know Intex provides filtration with their pools that is an absolutely minimal amount to meet the needs of the pool.
Hence I purchased a new sand filter today.
Three pieces of information are missing from the Sandpro 75D manual:
(1) How long should the filter run given the ~4560 gallon pool size with a rated pump output of 3,120 gal/hour;
(2) How many turnovers of water in a 24 hour period should there be;
(2) What is an acceptable maximum pressure on the gauge? There is no green/yellow/red indicator to indicate what is acceptable. There is 80 pounds of sand in the filter.
Also, what is the difference between 'Pump Flow Rate' (3,120/hr) and 'Design Flow Rate' (1,392/hr)?
Any input greatly appreciated and again, thanks for a great forum!
