Low PH- CO2 Scrubber worked for me

[chefmur]

My reefer 250 has been up and running for around 3 months, all was well except I struggled with low PH my guess is because we are in newly built house that is very airtight. I purchased a CO2 scrubber from BRS and hooked it up to my skimmer intake. PH went from high of 7.8 to 8.2, too early to tell how often I will need to change the media but so far I am very pleased. I was seeing great colors on my SPS but not having any growth or encrusting so interested to see if things start to move now.

Great, let us know what changes you see, if any.

I had a similar experience with about the same improvement in my pH. One thing I would recommend is to modify your skimmer cup with a hose barb to draw humid air directly into the scrubber. The use of humid air resulted in increasing the life of the scrubber media from 7-10 days on average to around four weeks.

Where does the hose go to ?

If your cup overflows will it pull skimmate into the co2 scrubber and then into your skimmer?

I was worried about that also. I eliminated the problem of the skimmer overflowing altogether by installing one of these little doohickeys: AutoAqua Smart Skimmer. Works great.

Thanks! I never knew those existed

My scrubber setup. A solenoid in the blue box is controlled by apex to open when ph is above 8.25

Pulls air from skimmer cup through media through two 1/4" lines.
