So after much thought I decided to try a CO2 scrubber. My ph was dipping down to 7.6 and I wanted to raise it. Already have a line hooked up outside but I guess it wasn’t enough. I found some very helpful videos about running it through the recirculating method which will help the media last longer. I decided to try this to see how it goes. I not only did I recirculate it but I also bought an electric valve to open amd close to the outside air utilizing my Apex to keep ph stable between 8.1 and 8.3. Fingers crossed hope it works. If it were not for people on this forum as well as R2R I would be lost. There are so many helpful people amd I greatly appreciate it. Here are a few pics. It is not currently running yet because I am waiting for a break out box abd float switch for my remote DIY skimmate locker.
