Hey, I'm Jeff.
I'm a power plant engineer in NYC and just bought a house 2 yrs ago with a 16*32 IG 20,500Gal
It has a lop loc cover and its been a swamp the past 2 years I've opend it.
last year i had a pool company open it many to se what they did which was pretty much, pull the over off letting every thing on the cover drop in. It was a swamp they set up the pump, said keep shocking it, and run the filter.
Great, well every time I vacuumed, the DE filter and the suction basket and the skimmers would get plugged. So with the help of Ebay, bought a 1.5hp hayward superpump, hayward cx900 cart filter and a few valves and PVC and build a stand alone vac pump. worked great. Wasn't into the chems like i should have been, Just watched the Cl and PH with a little drop test kit i bought. Seemed to work. Water stayed clear most of the season, Weather was cool and only was in the pool 3 times, hate cold water!!
This year It was "Do it yourself time." with my tag line "How hard could this be."
I pull cover, I see black swamp. I shock , I shock. I pour hypo 5.3%, baking soda, I find this website and its like chem class all over again. 7.0/7.3, 8.0 oh shoot how the **** that happen, TA=50/80/180? shoot.
I decided to replace the DE filter, only because I have nowhere to backwash it.
I replaced it with another hayward cx900 using the same 1.0hp superfilter.
while i was trying to build new piping I had a jumper hose from the skimmer suction to the vac pump.
I figured this will clear up shortly, One mans shortly is another mans long 2 weeks. after i started i got called for jury duty and had to stop everything in the middle, long story short, after 3 weeks and over 40 gals of hypo and powder shock and other stuff I should have not even bothered with I'm starting to see the bottem of the deep end.
When they say POPP oh man do they mean it!!!
Good luck to everyone who knows whay a swamp means!!!
