Agreed.Yeah you will have that. The cloudyness is organics that haven’t died. Keep your bromine up and it will go away. Just like a pool you just need to keep it up for a while. Its not so much about shocking ad providing constant sanitizer. The bromine will burn out most detergents but not all the way. The tub will get more and more foamy with use (unless you are one that either soaks naked or pre shower and use the same swim suit). I don’t worry much.
It’s nice when there’s no foam but it is what it is. You can get defoamer to knock it down but it won’t be permanent. Once your water clears up it should of burned off most of what could be causing the foam. Next time just add a tbsp of shock or bleach while they are using it. Don’t need a case of jock itch spreading around the neighborhood lol
Also what’s your ta?
you might need to shock the bromine by raising it above 10ppm. Bromine always seems to smell a little bit but if in doubt dump in bleach or the dichlor to get it up to 10 and let it run down on its own.
