IMO, seaclone's are the more moody than my girlfriend
Seriously though, I used to have one.... waaayyy back.... I would spend 90% of my time adjusting the air valve, and as soon as I got it set it would be time to clean the skimmer or the air hole would get clogged or some other PITA reason that I had to take it apart.
I'll give you a word of advice I wish someone else would have giving me many headaches ago...... Throw the seaclone in the trash.... or give it to your worst enemy, or use it to hit the person who sold it to you over the head, or...... go ahead and schedule all of your free time to getting it to work.
Seriously though.... do what you can with it.... it's a battle I thought I could win yet ended up failing miserably. I made a DIY skimmer, took one weekend, and have never looked back. I don't even have to touch it... it just works no matter what.
Good luck with your new tank!
