SWG install tomorrow

Is your Circupool SWG powered on and generating with salt int he pool?

CL = chorline
 
Bubbles is good.. its CL gas! burp,... excuse me

Actually SWGs generate hydrogen bubbles, not chlorine.

It's those hydrogen bubbles that can explode if the SWG is powered on when there is no water flow.

I have enough salt in the pool to enact the generator but we got done late so I’ll check the water balance again in the morning & then set the timer etc & turn on.

No, the generator isn’t on now.

Then the bubbles ae not hydrogen from the cell. They have to be air bubbles that you normally don;t see since your pipes are not transparent like the cell is.

Wow! That was quick. When you have the unit running most of the time you'll see a fine blanket of tiny bubbles coming off the plates. Don't be alarmed if it stops periodically. It cycles through production, reverse voltage, and rest.

Congrats!

SWGs generate chlorine gas and hydrogen gas. The chlorine gas dissolves pretty quickly in the water. Hydrogen gas does not dissolve as much. So, if you're watching the returns, you should only see hydrogen gas. If you're watching the plates through clear cell walls, you can see chlorine gas being generated.

The bubbles on both sides of the center plate are hydrogen or chlorine depending on the polarity.

Bubbles form on the inner walls of the outer plates but not on the outer walls of the outer plates. The bubbles on the center plate are the opposite of the bubbles on the inner walls of the outer plates.

The plates between the center plate and the outer plates have chlorine bubbles on one side and hydrogen bubbles on the other side.

When a cell explodes, it's due to the combined chlorine and hydrogen gasses.

Hydrogen gas needs an oxidizer to burn. Usually, the oxidizer is oxygen, but there's no oxygen available.

There's no oxygen, but the chlorine is a better oxidizer than oxygen and produces a faster reaction.

Yes, they are air bubbles. Do I need to get them out of there before I turn on the SWG? If so, how? Do I back wash til they’re gone?

I back washed for a few minutes when I turned the pump back on & then rinsed. When I turned the filter to filter, the bubbles stayed in the cell.

Do I need to retest the salt level since I backwashed?
 
If you're sure that the SWG is not on, the bubbles have to be from the suction side.

As long as the bubbles are not too much, it's ok to run the SWG.

Hopefully, you can find the suction leak.

Idk if you can see how large the air pocket is but imo it’s not small. I just don’t want to mess anything up.
Is this bubble too big?

It hard to tell. How much air is coming out of the returns?

Maybe put the hump down to help clear out any air from the cell.

It shouldn't hurt anything. It might reduce the chlorine production some.

If the system is off, is there a leak on the suction anywhere?
 
Holy smokes! I had intended on replacing my lights (@ the top of the pole) with LED bulbs. Is that a bad plan? Bc from this video it doesn’t look like a smart one.

The bulbs are about 7’ away. Off to the side (no direct light pointing at the cell) & higher up. I hope I’m just being overly cautious and not ridiculous.

I’ll turn the cell over tomorrow morning and get the air out. Hopefully that’ll work. If not, I’ll start looking for a leak
 
The gas has to build up quite a bit before there's any real danger.

As long as the cell isn't generating with no flow, it should be fine.

To initiate the reaction, the light needs to be short wavelength.

The cell might even block short wavelength light. I would hope that the plastic blocks blue and shorter wavelengths.
 
Tracey,
As per circupool customer support of 3 weeks ago, they recommend having a roof or shelter over the control. Even though it's designed to be outside and is quote on quote waterproof. The guy said to me if you want longevity with control keep it out of the elements, direct sun and rain. I did just that. Nice install. Not sure why you have that air bubble but possibly it's not level and that's what keeping the bubble out of the water stream. If you bleed off the air at the filter you will get full flow and push the bubble out. Just looked at your signature only to see you have a 22000 gallon pool. That unit you have is almost 3X pool capacity. You'll be running it very low%. I have one installed on a 28000 capacity pool, have it dialed down now at 30% and still have a FC -9. That's with a water temp of 87° and non variable 1.5 hp pump running 12 hours. Watch the PH as that tends to rise slowly. With it running 3 weeks I still didn't need to add MA with PH of 7.6 now. Make sure your numbers are good and keep the CSI in negative territory for a clean running cell.

I plan on putting up a roof type structure to cover it & the rest of the electronic things. I really need to put a structure to cover the pvc pipes from the elements also but that will be further in the future a bit.

Why did I not think of leveling it ??‍♀️ I’ll try that before I turn it upside down.

I purchased this unit bc I figured the size would help it last longer bc if the low %. 3weeks?! That’s fabulous!

Yep... they make both CL and H, the H you see in the form of bubbles... I suppose its a bit inaccurate, but if there are bubbles, CL is being produced. @JamesW .. cool vid.

Yeah.. that amount of bubbles doesn't look like normal operation.. they make the cells clear so you can see the bubbles coming of the plates and have a quick way to inspect the playes for scaling. When you get the chance to post your next pic, include some of the piping that you installed. The plumbing gurus here have a good eyeball for seeing inconsistencies.

The good bubbles we're talking about are microscopic so to speak. You'll see sort of a haze or fog moving from the plates disappearing into the pipe pool bound. When it's in the off cycle period of running dictated by the % chosen the cell will be clear and control will have the chlorinating indicator off. The amps at that point will also show 0 amps. Love the unit.
