High CYA somehow!? Is it ok?

[mknauss]

In your other thread you added enough stabilizer to get to 40-50 ppm CYA. You say you have 90 now. If true, you need to drain 50% of the pool volume to have any chance of success.

Thanks! I have the pump on 24/7 and I'll keep it going. I want to turn off the SWG while slamming, right? Do you think just brushing while slamming will be enough, or do you think I need to vac? If I do drain some, how much would I need to drain?

Yes, keep the SWCG off during SLAM - use liquid chlorine to keep your FC up. After finishing your SLAM, perhaps start at a higher run time for the SWCG and slowly back off if FC drifts higher...

Vacuum as well - and perhaps just vacuum to waste to start replacing some of that water. CYA of 90 is going to be hard to do a SLAM due to the large amount of chlorine required. I found that vacuuming to wasted was helpful if you can manage to replace the water - just get rid of the gunk that's floating around and don't foul up your filter.

I normally have it run 6 hours a day (but it was completely off from the salt error). Should I bump that to 8 hours a day?

If it was at 1.5 because the SWG was off then would need to wait for things to get back to normal to figure out how much extra time is needed. If it was at 1.5 when the SWG was working, then you need to double the time at least.

It says 90 is ok for an SWG? I have no idea how it raised because I put nothing in it but liquid chlorine/bleach since doing the CYA. Unless I did the test wrong? Does the dot actually disappear or just disappear for you because the water is cloudy? I can see the dot from the side, but looking down the tube it disappears because of cloudiness.

 

[wireform]

The cloudy water will still let you test for CYA. Test with glancing from the top and call it when you barely see the dot. After all you may not have that high of CYA if you didn't add since 40-50 Marty mentioned.

That sounds good. I have a cartridge filter but read that I can remove the filter and the top lid and just let the water flow out that way. Then I can add some fresh water. I'll probably retest cya before I do that because I don't understand how it could have raised on its own.

The gallons could be off either in poolmath or the pool itself, you mismeasured the add, the neighbor tried to help out and dumped some powdered shock in……. What’s done is done.

Although worth pointing out for future use, the manufacturer rates your gallons as full to the brim and you are about 6 inches lower than that. Your less actual gallons will give you a higher add than expected if you don’t account for the loss.

Kill two birds with one stone and vac to waste if you can. The more that you get out that settled on the bottom the better.

The SWG won’t keep up for now, and once it’s able to, you’ll need it off to Overnight Chlorine Loss Test. So leave it off as said above.

It’s really subjective. Maybe it was 80 the whole time and last time you saw 70 and this time you saw 90. Good idea to make sure. Reuse the sample as many times as you need. Keep sucking it back and forth until you get 3 out of 5 that agree. Or 8 out of 10 if need be.

Ok that's what I did.

I find it easier to unscrew the nozzle and pinch the CYA tube a bit, makes for an easy pour.

That makes sense. I didn't know about adjusting for less water. I'll check it out again and see what she says, and get a good vac to waste in if it's still reading at 90 and then add some fresh water!

50%?? Wow that's huge

 

[Newdude]

50%?? Wow that's huge

Think he missed the SWG part. 70 is good. 15-20% drain is close enough.

He meant since a SLAM is in the works, less CYA is better for that.

True.

*what I missed was that with a small pool it’s a lot easier to drain half for the help in the battle.

if you can ChelleSte , you drain half and only have to fight the other half. It’s more work to make it a lot less work if that makes sense

 

[ChelleSte]

So can I drain that much by doing a "vac to waste" the filter cartridge way? Basically the pump is just pulling it out and it's running through it without a filter in it. Can I do less like the 20% and just use more chlorine? I'm worried 50% with refill will lead to a freezing cold pool on Saturday.

 

[ChelleSte]

It does, I'm just worried the pool with be freezing cold on Saturday then.

Depends on your expectation for this pool party. If cloudy water is acceptable, then stay the course. Your filter system is not robust enough to clear this pool in a short time.

I just want it comfortable for the party. I can get it sparkling afterwards if need be. It's my (young) nieces and nephews so I don't want to freeze them lol

If you got it done tomorrow I think it would be plenty warm on Saturday. You have low 80s for tomorrow and Wed and 87 highs on Thursday and Friday. It should be plenty of time to warm up.

Nothing make us run out of things like coming home from the store.

And nothing makes us forget things like walking into the store… lol

“Now what do I need???”
