Adding a co2 scrubber to my tank. Does a rapid increase in ph cause any problems?

[glb]

To answer the ops question, yes it can cause problems. I saw burns on some acros when I tossed a rather large one on my tank, and I thought I remember others on here saying the same thing at times. I would take it slow and only run it half a day for a bit.

I’m wondering if I really need one. I like the idea of running it for less time, maybe overnight would work.

7.8-8.0 is perfectly fine. Even with calcium reactors people get average from 7.6 to 7.8 and that’s shown just as good results.

I am selling my CO2 scrubber because I personally don't think it is worth it to chase PH. I also found dosing two part raises my PH so I set my apex DOS to do very small quantities to keep it more consistent. Also, PH swings are normal on a daily basis (when you have your lights off). Not to mention the media is expensive to replace every week (and another thing to do!).

Just as good as what? Acceptable to the reefer? Fabulous looking tank? Sure, I accept those.

But very few people can say with any confidence that their tank would not grow somewhat faster at higher pH.

Not everyone wants faster growth, but I think it is somewhat pushing the evidence to say it must be just as good.

I open a window in the room where my tanks are in both the fall and the spring (too cold in winter; too hot in summer in Middle Tennessee) and I see the pH go from 7.9-8.0 range to 8.2-8.3 range fairly quickly. No ill effects that I have been able to discern.
