CA reactor or Dosing?

I give it a good wipe/rinse every time I change the media cause the probe goes in the lid. Seems to work well I guess.

So every 4-6 months? That I could manage

Just to let those that might be interested know and I hope I'm not interjecting here.

I don't bother with pH control in chamber. The reason is that if the flow through the chamber stopped or the probe failed, the controller had no means to handle this (i.e. no controller wind-up proection). I use a timer instead and bubble CO2 in the chamber for a period of 9 minutes every hour. The bubbles are introduced at a good rate and I'm sure that the pH in the chamber is dropped to a level that the aragonite will dissolve. I used trial and error to come up with the 9 minutes, just as one would with finding the sweet spot for a 2-part doser. I don't bother trying to target any particular bubble rate - just vigorous bubbles.
