Where are you reading that HTH sand is superior in Intex sand filters? I am not aware of that.

Too lazy to link it all cute.
You'll see there is lots of talk about what works and what doesn't as well as the OPs original problem, thought to be a multiport valve issue, but it wasn't after all. The OP had been through 3 or 4 different brands of sand.
Many people posted problems with it blowing into the pool at start-up, some a fountain of never ending sand as the OP did, and so on, all with inferior grades of sand.
I'd say it's pretty definitive, this really should be pinned as the OP suggested.
This is interesting as well, it describes the sand problem itself, mainly with the manufacturers of the sand.

I knew about the particular sand, I read also before I set it up and when I was having problems at the beginning with sand in the pool. But check this out, I went to Intex and downloaded the PDF manual for the 2650 under SF20110 because I was sure I did not see some actual laterals in it. I will attach two pictures, one will be a snap shot of the PDF manual where u can clearly see the laterals, the other is a picture I took from my manual, same id, sf20110, where there is only a grate at the bottom of the tub and not several laterals suspended in the sand. This is the one I have, only the one grate. Thats what I think may be the problem, no laterals and only a grate that sits on the bottom of the tub. I dont see how this would work correctly but I may be wrong.
This does appear to be the case, I went and looked this up again and it looks they have recently changed the design to include latterals.
I knew there was a plate down there, but was stumped when I didn't see it in the specs for the new model.
Now this makes sense, they got rid of it in lieu of latterals.
Hopefully this is better than the previous design.
You should inspect your plate for damage, make sure it's seated all the way, etc..
Also, take a stroll through that entire thread I posted a link to above, if you're up for some reading & learning.
There's a lot of good info in there, 1st hand reports from users like yourself that have these Intex units.
