Hello, I recently inherited a 24,000 gallon in-ground pool (along with a house ). The pool had been laying dormant, uncovered, for 8 years, so my wife and I drained it, cleaned it, and refilled it. That was a VERY nasty job! LOL
Anyway, the only water we had to refill it with was Florida's notoriously bad iron-laden well-water. The pool is 10 feet deep, and when we first filled the pool, the water in the deep end was actually black! After a couple of weeks of shock, chlorine, and a few other usual chemicals, we ended up with perfectly clear water, but with a catch.
After we filled the pool, we put in six quarts of "Metal Out" because our local pool store told us that by putting this stuff in, the metal would be sequestered and we would be able to just vacuum it out. Well, that only turned out to be half correct. The chemical definitely did it's job of sequestering, but it goes right through the filter and back out the jets again every time I try to vacuum it up.
I have a brand new 2HP pump and a new 225 sq/ft cartridge filter. Every morning, the water is crystal clear and you can see right to the bottom of the 10 foot deep end, but across the bottom of the entire pool is a brown dust-like substance. I'm positive it's not algae because I also put in algaecide and some other stuff to take care of that (because that's what I thought it was at first). Like I said, every time I try to vacuum it up, it just goes right through the filter and back out the jets, and the water remains a cloudy green/brown color until it all settles back to to the bottom again overnight.
Is there any way I can get rid of this stuff? It was suggested that I simply bypass the filter and vacuum the stuff straight out, but the problem is that my 2HP pump moves the water so fast that the water level would be below the skimmer before I could finish, and then I'd just have to use the same well water again to fill it back up and start the process over again.
If anyone has any ideas or experience with this, I'd be extremely grateful for any advice you can provide.
