Ok Gents, here's your stumped FNG question for the day.
8-10,000 Gal, inground SWG pool in Virginia Beach. Hayward 4800 filter. New pump motor last summer. Passive solar heat on the roof of the house.
Just popped the cover and vacuumed the majority of crud. Brushed the vinyl sides. Fired up the filter, added 7 scoops of DE in the skimmer. To the pool I added a small jar of shock, 3 gallons of bleach and a half a gallon of Muriatic Acid.
Everything started clearing up and looking much better within an hour. But, then the flow just about quit. Cleared out the skimmer basket and the basket at the filter. Both contained an expected amount of pine needles and junk but nothing outrageous. A fair amount of foam present, but not crazy.
Here's my dilemma -
After about 30 mins the flow though the filter goes to ****. I did a quick backwash thinking I had trapped crud or air and got things flowing nicely again. Went to Homies Despot and upon return was greeted with the same old ****. What can cause this situation?? Initially I have good flow from the pool outputs and good suction at the skimmer. An hour later, it doesn't suck and it doesn't blow.
Can anyone toss this moron a bone?
