Does PH down not mix completely in a res? PH shoots down when pump kicks on.

It hasn’t added enough to be noticeable. At the same temp as it was before I added it

nice. how big is the res?
I used a similar device in a 16 gal res tank and the temp rose noticeably faster with it on than off.

I have a 20g Brute and 25g Flexitank Pro. No difference in temp. They only use like 3 watts or something

may or may not have anything to do with it...but oxygenating water makes the PH drop for a few minutes...you can make it drop quite a bit just stirring it by hand with a stick.
