June 2017 the Wife and I bought a Summer Waves Elite 16' X 48" round AG pool, it came with a SFX1500 PLUS Complete Filtration System with GFCI Pump, canister filter. Everything was going good until the middle of August, I had to vacuum it every day because as soon as I got it clean it got dirty again and then the pool started turning green, so I shocked it, the green went away but stayed cloudy. I could not get it to clear up. I decided to buy a sand filter and installed it. then I used Alum as a flocculant, the next I vacuumed the pool and the water was very clear. But everytime I vacuumed the pool a few hrs later dirt was on the bottom again, by this time winter was here and time to close the pool for the winter. I open the pool in April and still vacuuming and hrs later still had dirt back on the bottom. After doing some research most sand filters have a waste port which mine does not, ( had I done more research before I bought the sand filer I would have bought a different one). still more research I found a Hayward 3-Way PVC Diverter Valve which I have installed before the sand filter and connecting it to the backwash line and now all is good.
My last test results are as follows:
FAC 10 (I shocked the pool last night)
TAC 10
CH 200
CYA 50
TA 90
PH 7
TDS 1000
