So I picked up a gyre and put it in my 120 tonight. Not bad as it does really punch out a lot of flow. My problem is this. If I go below 40% it stops and the center button in the ring flashes red. Manual says read trouble shooting.....none to be found in box as hard copy. Go to website to register....no choice selection for gyre. Back to trouble shooting and I can't find it on said website. Now getting annoyed.....played with it and can change settings/modes but if I drop power below 40% it stops and controller flashes red. Do I have a lemon? Coralvue website is not giving me much info and I'm getting annoyed!
