100 Cya in a Spa to Pool with 80 Cya

[DavidBenedict]

In the interest of conserving some water, I’ve once emptied my external spa into my pool (it’s not joined together). I Never had any issues, pool remained clear. I’ve been monitoring my CYA situation I use to use dichlor in the pool but now solely switch to liquid. My CYA in my pool was at 110 about 4 months ago and is now down to 70. Anyhow my cya in my spa is about 100 it’s a 425 gal cal spa and I have a 13k gallon pool. If I dumped my spa into my pool this time does anyone think my cya in the pool would spike again or is 425 gallons a drop in the bucket?

David,

If you dump your 425 gallons of spa water into your 13,000 gallon pool, I am not sure you will even be able to tell the difference in the pool's CYA level.

Thanks,

Jim R.

It would raise the CYA in your pool by 3.5 ppm. Not measurable.
