Hello @ReeferJay86,How long do you run you algae scrubber? I’m having a hard time trying to maintain a high ph. I have a IM 30long and I have chaeto in 2 chambers and use the IM Refuge light. It turns on as soon as lights go out and off when they turn back on, around 12 hrs. In order for my ph to rise I have to open the door and window every day to get it over 7.8, then it will drop from anywhere of 7.5-7.6
My configuration might be a little different than most, I currently have an overlap of an hour (2hr total) from when the main tank lights go on, to when they turn off (total run time of 17hrs) for the scrubber. I also have a CO2 reactor (with tightly packed media) in place to control my pH as my basement/man-cave is VERY airtight and I don't have much air exchange unless I open the bulkhead (and interior) door/s.
I hover right around 8.1 - 8.3, however, the higher values are also equated to dosing soda-ash (Na2CO3) throughout the day/as needed.
Hope that answers your question?
Thx!!
Edit: Opening the door/s is not an option for me in the northeast with the cold, however, when I can my PH is much higher so I tend to remove the CO2 reactor in the spring and fall.
