is my co2 scrubber still needed?

[david campbell]

ok my large DIY co2 scrubber hold 6lbs of media. Its been running the same media now for several months, maybe 4 months or more months old with 0 color change ( what a joke that label is) anyway, my ph is still running well and high...

1. is the media still working after several months of use? research says it should be exhausted by now.
2. if is exhausted then why is my ph still high? raisieng ph was the goal of the diy scrubber.
3. should i take it off line and watch the ph?
4 do i even need it now that the co2 levels in my tank have clearly been lower ( higher ph).

If you don’t need the space then I would leave it hooked up and see if it eventually decreases. If you need the space where the scrubber is I would unhook the line and see what your pH does.
I am new to using a scrubber and mine is the small BRS one that takes around a pound of media and I haven’t replaced the media in 5 weeks and it’s still raising my pH. I do run an outside airline to it though.

Generally reefer reports that this type of media last 2-4 weeks.
You might have well ventilated, low occupancy house.
yes take it off and watch pH.
You probably don’t need it.

The other alternative is it's not sealed super tight and the venturi isn't pulling the air through it but instead through the open cracks.
