I WANNA SEE ALL 15 MINUTES!!!!!

(no, not really )

[FormerBromineUser]

I would watch and advance the timer to 15 minutes... If I had the link!

[kelemvor]

yeah sorry, maybe tomorrow I'll be inclined to make a better video when it's daylight.

[FormerBromineUser]

We're even now! I accused you of knowing about freezing pipes, and you deprived me of a cavitating.... oops, a captivating video! Heehee

Gentlemen,

It's hydrogen gas bubbles. They are produced in the cell. One electrode produces Cl which mostly dissolves as hypochlorite/hypochlorous acid and the other electrode evolves H2 gas which is not as soluable in water

Definitive ChemGeek thread is here

The pH rise is both due to aeration/CO2 out gassing and the production of hypochlorite which is alkaline.

[kelemvor]

Yup, there ya go. That's the thread I was thinking of. I didn't realize it was on the other forum.

Just remember, for fire safety, no lighting matches near your returns

Mine produces visible bubbles at the returns as well. I use to have rising pH, but since lowering TA to about 80 (I use to keep it around 100) the pH rise has pretty much stopped. It's been 2 full seasons since I've added acid.
