Hi all, my name is Gary from Long Island, NY. I opened my 16 x 32 above ground pool equipped with a 2 HP Hayward pump and sand filter model TM -12 about a month ago...still haven't dove in yet.
Mistake number one was on the initial start up of filter. I shocked it. Added 14 lbs Alkanlinity, some calcium, algaecide, shocked again and again...then realized I hooked up the hoses wrong. I went from the skimmer to the pump. From pump into return on filter. Then from pump on filter to the return on the pool. So, nothing was getting filtered. The water was just getting pumped back into the pool. Question # 1: I shut the pool pump down in frustration and was surprised after two days that I could see the bottom of the pool. I also saw a layer of sand from one end of the pool to the other. How did all the sand get into the pool? It's a decent amount...so.
I emptied my filter of all the water and am going to change the sand that's left in it. Question # 2: How much sand do I put in the sand filter? I don't even know what brand it is because the pool and filter came with the house when we bought it. Model TM - 12 is all it says. It has filter, waste, backwash, rinse, recirc, closed on the top piece that swivels to each choice with a black handle.
Question # 3: Can I vaccum up all the sand after I replace all the sand in the filter without screwing something up by putting dirty used sand back into the sand filter?
I think this will solve my problem and the reason why the pool would not clear up and all the sand got into the pool was because I hooked everything up wrong...does that sound correct??
THanks a lot.
