this is getting worse. We left to go camping for three days, came back and pool had a slight green tint so I immediately added 1lb of shock n swim (calcium hypochlorite) and 3 gallons of 6% bleach. let the pump run all night. this morning it was almost no green but slightly cloudy, I tested using strips and it wouldnt even register any chlorine. So I added another lb of shock n swim and another 1.5 gallons of bleach. So now my pool is dirty AND cloudy. Running the filter and pump seems to be helping none. WE are going to take apart the sand filter and see if the gasket is going bad or if the sand has "tunneled" or if its low? I have no ideal about those things, its just something I read on here as possible problems for improper filtering? Also I intend to keep adding bleach keeping the chlorine level high for a few days?. Then scrub pool, vacuum to waste and if water still looks dirty, add DE powder to skimmer to see if it will help the sand filter catch smaller particles? Am I thinking on the right path?

oh and all last summer (our first) I used the tabs , was afraid of getting a cya(stabilizer?) build up so intended on using only bleach this year. When I tested on my strips this morning, the stabilizer was 0. I know I need that testing kit and I plan on ordering it from amazon this week.

ps its a 24'x52" above ground pool with a jacuzzi 1.5hp pump (no high or low speed) and a sand filter.
