Still brushing off some, I can see its really brushing off in some spots where the coating was not as concentrated.

T A is most certainly coming down, its at 120-130 now.
ph holding at 6.8
Chlorine down to 1.-2.

Kids want to swim tomorrow, would you think its ok to let them in there for awhile? Didnt know if thats a good idea with the adjusting im doing?

Thanks again,

[PoolDoc]

Yes.

How's the battle with the grit going?

[Wapak]

Well, I am glad to report having a bunch of rowdy kids swimming in the pool seemed effective to pull up some of this stuff-there literally were piles of this grit in the corners, and on the floor which i was able to vacuum up the next morning. They also didnt even notice it as they were swimming, of course, its always on my mind, but they could have cared less!

There has been substantial amounts that have started to come up especially in the shallow end floor and the deep end floor.

I still have several areas on the walls, and on the seams around the deep end that just want to keep holding on.

I brush every night (i dont scrub), and every swipe does produce a cloud so I know its coming loose, just not as fast as I guess I want it to come off!

My TA has been difficult to get below 120. TA has held now for the last four days betw 120-140.

I have my returns turned up, and I use a power nozzle on my fill hose to spray over the surface of the pool water and create bubbles and fizz, but am thinking I may need to get a little more agressive on my aeration?? I saw where some have rigged up pvc pipes to do this-do you suggest that, or just stay the course with what I am doing?

My PH as come up several times (last read this morning was 7.5), but I just add a half gal of muratic acid and it drops by the next morning to 6.8.

Another question though, each season I use the Tri Chlor pucks in my chlorinator, but have not used any yet since opening the pool. Would you suggest that I go ahead and start putting the pucks in my chlorinator?

All in all, I would say I am winning with your advice, just have a feeling this is going to be a long war!

Thanks again PoolDoc

The calcium carbonate bits are INCREASING both your TA and your CH, as they dissolve or break down. So it's not too surprising that you're finding your pool resists going below 120.

As the sand algae bits diminish, you should be able to lower the TA, and clean up the remnants.
