Filter cartridge cleaning???

[prh129]

When I do clean the filter, there is just dirt, pollen and some small fragments that manage to get through the skimmer and pump baskets. I wouldn't say my filter gets "gummed up" using chlorine.

Biguinide doesn't burn up (oxidize) bacteria but causes them to explode and that is the junk you see in the filter. A lot of people refer to is as Baquagoo! This doesn't happen with either chlorine or bromine.

I have a 13,500 gallon IG pool with SWCG and Lowzone. I have a 420 sq ft Pentair cartridge filter. I clean the cartridges once a year even though I never see more than a few psi pressure increase. When I clean them, there is some dirt and this year, some blue scales from my old solar cover. There's a little staining on the cartridges, but no scale and they clean up nice. I haven't had to soak them yet in anything, just hose them down. I figure this may be the one benefit I get from the Lowzone. I think it burns up a lot of the junk that would build up in the filter if I didn't have the lowzone.

The only pressure guage I have is on the pressure return pipe where I connect the Ray-Vac. It's a Foxx Pool.

I guage the cleaning based on the sound of the pump and qty of air in the basket area on the pump.

When the filters get clogged, return side pressure decreases and air increases.

You learn a lot in the first few weeks with a new pool.
