CO2 scrubber disappointing results

[coastal_kid]

All my sps I’ve had since tiny frags. I manually dose all my major and minor elements. When I test and alk gets low I’ll increase alk by 1.4 dkh in a day. That is what Red Sea said was the limit in their dosing manual. I was new and I didn’t no otherwise. Been doing that since I’ve had sps(like 10 months) and they’ve done nothing but grow like maniacs. Ain’t nobody killin sps with a little alk jump lol. I’ve learned to dose a lol each day based on consumption for “stability” reasons but even then it’s drinking .4 a day technically that’s a .4 swing per day right?

Sounds reasonable to me.

You can do whatever you want but there are many acros that aren't going to tolerate a 1.4 dkh swing.

Agree that you dont want to resirculate the skimmer air through the co2 scrubber.
This was my nano 25 gallon sump.
I dont have a pic of the scrubber but you can see where the air is going into the skimmer, the open orange line, that is where I attached a small bottle of soda pellets.
It worked well for a small tank but really ate up the media quick.
It pulls the air through the media and into the skimmer, thus filtering out the co2 allowing plenty of oxygenation.

Found the old scrubber pic on my nano.

Should the media in the scrubber compact tight or loose?

Just pour it in and go. No need to try and pack it in.
