A friend of my daughter has an Intex Pool - it's cloudy and green. The dad is a faboulously talented artist, mechanic, jack of all trades. He has maintained pools with traditional methods without problems for years - but this is the 2nd year with his Intex and he had no idea what a toy filter it was. The dad has his CPO and seemed a little reluctant to move to BBB but I've talked him into at least letting me test the water and help him figure out how bad things are.
What I need are ideas on how to improve filtration for this pool without switching filter systems. He has a sand filter and pump but they are moving to another house and until they move he does not want to drag that stuff out for the 1 month or so of swimming left in the season.
He's a firm beliver in flock and he's tried it - but when he does it the stuff goes back into the pool; the filter just can't stop it. So we discussed ways to do it and vacuum to waste - one of which was to disconnect the return during vacuuming. After that's done I'm going to help him with FC levels for a while trying to show him the BBB method of shocking. Since it's not my pool and he's a CPO he may fight along the way. We shall see - he admitted that he's never had a pool this hard to deal with.
Stats: 5500 gallons roughly, Intex Cartridge A combined filter/pump. Pool pale green - very cloudy.
Chlorination - pucks and "shock bags" (not sure if dichlor or trichlor or cal hypo yet). Hang over the side skimmer, plunger valves. No measurements yet - but I'll get some posted as soon as I can test the water with him.
