So, not sure what to do but wait at this point. Pool water is still cloudy. Could I go ahead and change the sand and see what happens? Surely the biguanide is gone by now? Sock with more chlorine?
Channeling can ALSO result from an oversized pump.
You have to understand, pool dealers want to sell pools, more than they want to sell pools that work. American customers tend to be much more impressed by "MORE HORSEPOWER" than they are by "BIGGER FILTER"! Plus it's cheaper to 'upgrade' to a 1.5HP pump from a 3/4 HP pump, than it is to upgrade from an 18" filter to a 24" filter.

Yes, probably.
And that will also answer the question, "Have you lost sand, because of the oversized pump?"
Be *sure* to use labeled filter sand . . . do NOT get Quikrete sand from Lowes, etc.
Yes, the correct sand is ready and waiting. Just had a big rainstorm, so will probably do it in the morning. Thank you.

Does someone make a tablet that deos not have CYA or calcium in it? I have not seen anything yet, but the convenience of a tab in a feeder without the other junk would be great.
Nope.
I suppose it might be possible to make tablets of lithium hypochlorite, but I've never heard of having that done.
And, now that salt water chlorine generators are the 'go-to' solution for convenience, I very much doubt that it ever will. Of course, it might be interesting to find out what high levels of lithium chloride would do to swimmers, given that it's a psychotropic drug, used in times past to treat bipolar disorder!![]()
Hi,
After a long weekend, some important updates (and realizations) have been made:
1. We changed the sand in the filter.
2. I noticed the (defective) pump gauge showed 10 psi when it was off. So, the actual psi was 15, not 25.
3. Had a great pool party, in spite of the still cloudy water. (Tested ok enough to swim, fyi.)
4. Realized that we had been running the filter on the wrong setting so the water was just circulating instead of going through the filter sand...duh!
5. Added more bleach and DE.
6. Looking MUCH better already!
It is ironic that I have been doing so much research and testing, when most of the problem should have been obvious! Thank you for your patience and help. I am hopeful that the crystal clear sparkling water is just around the corner![]()

Yeah!
I can see the bottom clearly enough to effectively vacuum! I need to keep it at shock level for another day after it clears completely, right? When do I add CYA?

Yes, if your CYA is still less than 40 ppm, you need more. You can use dichlor.
Or, you add stabilizer directly. It dissolves SLOWLY, and mainly when the pump is on. If you add stabilizer to the skimmer, do it after backwashing, so you can avoid backwashing again for 3 - 4 days.
