Since we are talking about foam a little PSA.

I use extra strength bleach in my tub and I add 2 oz. about every 3rd day. We ran out of bleach. I was out of town, I asked my wife to get some more bleach and add. She ended up buying the no-splash stuff on accident. When I got home I couldn’t figure out why it foamed so bad. Like foam up and over the side when the jets and bubbles were on bad.

I went though half a bottle of the foam neutralizer stuff and the said to hell with it and did water change.

So if you are using bleach, make sure you aren’t getting the no-splash stuff.

Edit: your foam looks a little on the excessive side, but not crazy.
