I've had my PA for just a lil over 2 years now, back in Nov I went from a 10g to a 6g. I've always had some crusties at the top sometimes a lil bit of pain, figured it was the dry crusties. Cleaned it and everything was good. Just recently I noticed more crusties/pain, after having it out all day yesterday I took a good look at it and noticed it was migrating down Now I have a decision to make - A.) I've been wanting a APA for a good 6 months now, but just haven' gotten it yet... B.) Take it out for good and always have an open hole on the bottom of my PP. I have no plan on putting the PA back in, if I do I will go back down to a 10g or 8g but it wont be for a few months. Suggestions?
