Cya

[Russo221]

Ok question I recently lost about a quarter of the water in my pool due to a very strange episode that happened with my pool. At the time my cya level was at 50 which is where it should be for chlorinated pool. With that little episode losing that water and filling it up I tested it and it at 40 now, which it says between 40 and 50 is good. Now should I just leave it there or bring it back to 50?


By the way the strange episode was some how my tube from the pool to the filter some how came off and basically drained out till it got down past the out part in the pool..... Lol I have no clue how that happened.... It was clamped and all, very weird

If your FC loss per day is not excessive, leave the CYA as is.

I'd say I'm losing about 3ppm a day. But it has been very hot these last couple days with no rain

 

[mknauss]

Very normal.

That's what I figured.... Thanks...... I'm still in aw on how that tube came off ha, I check it like 2 times a day now ha ha

That is exactly why I switched to rigid pvc plumbing. All connections are either threaded unions or cemented. I toasted a shaft seal on my last pool by running my pump dry after a clamped hose popped off. PVC costs a few bucks, but it can save a lot more.

In this case, CYA means- Cover Your A....?

Hose ends can stretch out over time, and clamps can fail, vibration can loosen clamps over time. Lots of things could have happened.

Yeah that looks like what happened

The thing that's stopped me from doing PVC is my concern about movement in the pool wall vs the pump and filter.

Also, with 40-50 CYA what level of FC have you been maintaining? My understanding is this would require no less than 5 ppm of FC with CYA at 50. 5ppm minimum FC seems awfully high.

I keep my CYA around 30.

Right now at 40 cya level, it says 5 to 7 is the target level. 50 cya level is 6 to 8
