T-Cell-15 Producing Cloud Plum?

[PullJunkie]

I noticed today when my SWCG is on, there is "cloudy" water coming out of the jets. It almost looks like air, but it is not. When I turn the SWCG off, it stops. Is this normal? It seemed to start after I added some CYA yesterday, I forgot that I should have put it in a sock and ended up dumping it in the pool. Then I vacuumed it back up, I would think it'd be dissolved by now though if it was in the sand filter?

Is this normal?

Yes. The SWCG creates chlorine and hydrogen gas. The chlorine gas instantly combines with the water. The hydrogen does not, and is expelled as bubbles when the SWCG is generating.

Thanks, its weird though, why haven't I seen this the last week since I got it up and running? It just started yesterday and it makes the water look cloudy. Like it actually circulates around the pool with the flow of water.

We have had reports of that. Normally at spring start up. Seems to be some combination of water chemistry and possible water temperature? It goes away.

 

[PullJunkie]

Thanks, I'll keep an eye one it. All chemistry is good so far. Only difference is water temp has risen from about 80ish to 86-87 due to the hot weather here in PA and I added CYA yesterday morning as mentioned.

 

[PullJunkie]

Oh and I just remembered I did add some MA to decrease TA. Not sure if that has any bearing on the equation though. Maybe that with the CYA cause a reaction?

 

[mknauss]

I doubt it. Lowering TA and pH would not cloud up the pool water. No idea what the CO2 might do. Does it get added before or after the SWCG?

 

[PullJunkie]

It is after the SWCG. And I've only heard it turn on once when I first fired the system up last week. My ph stays pretty stable.
