Yes, that's how I do it. I use the same salt also, but if this is happening after the water change, then it's something you are adding during the change. Think about every step you take to do the change. Something is getting in at some point. Dirty bucket maybe? When was the last time you changed your RODI
filters? BTW, you should really get a TDS
meter. It's the only way to know you need to change your filters.
- I didn't see the last post until I posted this. So, you got this used octo and it's been producing micro bubbles ever since, and collecting no skimmate?
