To start off, I tried to make a post, but I am not sure if the forum ate it or if it is moderation limbo. Sorry if this ends up being a double post.
We just bought a house here in Florida (Fort Walton area) with an 18x36 in ground pool (3 foot shallow end, 8 foot deep end - 26,000 gallons or so). Apparently, this particular type of pool is called a Polynesian pool (what I was told - though not familiar enough to know for certain). It has rigid side panels (fiberglass I believe) and a flexible vinyl liner further down (about 3 feet from the upper lip).
Hardware that came with the pool includes a Hayward S244T sand filter, a 1 1/2 HP Hayward Super Pump (not sure what makes it super - but that is what it is called) and a Hayward 4.2 Chlorine Feeder. Visible Plumbing is all 1 1/2" PVC. The pool has three inlet nozzles on one long side and a skimmer about half way down the other long side. A single main drain is located in the middle of the deep end.
Since the house was unoccupied for awhile, my initial work involved clearing out leaves and various other organic material from the bottom of the pool. After that was done, I backwashed the filter per the instructions (let it run till it ran clear). So far so good.
Now, I got to the point where I started to use the pool vacuum to get up the fines from the bottom of the pool. There seems to be a very fine red clay silt which settled on the bottom of the deep end and settled in the seams of the liner. When I sucked it up through the vacuum it simply shot back out through the inlet nozzles.
Further searching in these forums had turned up this thread:

That might be what I am dealing with, however it really is behaving more like dirt. Regarding that particular thread though, it was mentioned that you can add DE to your sand filters and I am curious where more information regarding this might be found.
Also, any pointers which can be given regarding starting a pool up without knowing what the condition of it might be (things to look closely at regarding the plumbing and what not).
