Why won’t my clear water sparkle?

[gdav]

Vinyl inground 12,600 gallons sand filter….
My water doesn’t sparkle, but it’s clear. I have invested in the TF100 test kit And my numbers have been good. I was running the the filter 24hrs a day and still it doesn’t sparkle. I’m tempted to add a clarifier from the pool store, but I know that’s not recommended here.

Chlorine 5
PH. 7.5

FC. 5.5
CC. 0
CH. 250
TA. 100
CYA. 40

and everyday I swept or vacuum the bottom, we haven’t gone swimming yet. Any suggestions?

Try running your pool a little hot for a week or so. At 40 CYA, you are at the low end of your target range. See if keeping your pool at 7-10 for a while gives you the sparkle you want.

What do you mean by running it a little hot?

I mean keeping the chlorine at the higher end of the chart. For your CYA of 40, the target range is 5-7. You are currently at 5.5 which is the low end of the scale. I'm recommending keeping it 7-10 for a while and see if that does the trick.

You can also do a OCLT to truly see if you have algae, but the easiest approach is to just slightly bump up the chlorine and see if that does the trick.

Ok…..so I would add liquid shock to do that? Sorry I need a little hand holding. I was reading about the slam process and was struggling to understand it. Maybe once I wrap my mind around the terminology, it will get easier.

What @JJ_Tex said... Also know that what most people call "sparkle" has to do with sunlight playing on clear water. The photo doesn't show what surrounds your pool. If it's mostly in shade, you may need to be content with "just" perfectly clear.

How do you normally chlorinate? Liquid chlorine would be best and yes just add a bit more for the next few weeks.
