I recently acquired a schuran pico ca reactor. After many head scratching hours I finally got it dialed in for the most part. I have a simple question. The needle valve on my regulator is sticky...I think...I dial in the bubble count to 1-3 a second but then come back an hour later and it's 1 bubble per 5-10 seconds. Is this the needle valve or something I messed up in the plumbing. Effluent is 50 drops a min and around 6.6 6.8 ph. Depending on what the bubbles are doing. The input is from an aqua lifter and has a valve dialed down to about half speed. Effluent is not regulated. All plumbing is 1/4 inch rigid tubing and effluent is normal air line flex tubing. Could that be the problem? Let me know. Thanks guys!
