Today on BRStv, we have another episode of BRS 52 FAQ where we answer all of your frequently asked reefing questions from our popular 52 Weeks of Reefing series. This week we are answering googlereasllysucks question: "Would running a hose outside to fresh air and a CO2 scrubber have the same effect? I already do the hose but still have low pH?" If you have low pH there are some limited options to raise your tank pH directly without affecting other levels, and many of them won’t be able to hit that magical 8.2-8.4pH long term. Usually, low pH is due to excessive CO2 in the ambient air that is very common to find in most homes. There are medias that will absorb the CO2 and remove it from the air passing through, that can hook directly to the air intake of a protein skimmer. CO2 absorbent media does need to be replaced regularly depending on the amount of CO2 it is scrubbing out and the reactors size. Running a hose outside is going to be the best all-around long term solution. Since CO2 media is not cheap and when it is depleted your pH will drop back down until it is changed again. Pulling the air from outside your home will keep your tanks pH much more consistent without the media maintenance requirements. If you have tried both solutions, and are still having pH issues, it could be that your skimmer is too small, or the tubing length is too long for the diameter and causing too much restriction. So follow along as we answer today's question, provide some helpful insight, and help make reefing just bit more fun and easy for you and your tank. *Legal Stuff* The purpose and content of this video is to provide general information regarding the products and their applications as presented in the video.
