Hi guys. I'm planning to pull an airline to get some fresh air into my skimmer to raise my ph close to 8.3. It's at 7.9 low and 8.18 high currently. Was away for a week and notice the ph actually went up to 8.25.
Here's the question. May I know which hose I shud b extending to my windows in picture below?the thick or thinner hose?
