New Salt System, algae is recurring regularly

Here's a little video. After it's been on for 15 minutes or so, there are far more bubbles than you see here. I turned it off so I could show off vs on and realized after taking 15 minutes of video that it would be VERY BORING to watch all of that.

The off/on cycle was to show that the bubbles weren't from a suction side leak.

I WANNA SEE ALL 15 MINUTES!!!!!

(no, not really )

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.

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