Survey: pH swing

[GKL]

Survey: how much of a pH swing do you get during the 24hr period? what are you using to manipulate it?

I have a afew refugiums on RDP and I do not experience any PH swing at all.

I dose kalkwasser 24/7 with a auto top-off system. I tested it just this morning and it was 7.8. It usually runs 8.3 during lights on.

8.0-8.1 in 24hr. I keep my KH around 15

8.1-8.3 in a 24hr period. I use Reef Builder from Seachem and that's about all I add.

I have no ph swing. It stays pretty stable no matter what. I add some trace elements, but nothing to fix ph in specific.

I wish I knew. My pH always reads the max on my test kit, 8.6. Can't get it down.

Have you tried a different test kit?

8.0 to 8.3 over 24 hours...

I've recently stablized my pH in the 8.15 - 8.30 range. pH naturally seems to rise during the day and drop at night. My pH swings used to be much more erratic, but since adding a refugium lit on an opposite cycle to the main tank, and running my calcium reactor on a controller, the pH has been rock solid. The calcium reactor runs unless the pH drops below 8.2. I don't use any additives. It appears that the range is tightening even furth. You can see mytank monitor to get a sense of the pH swings.
