I don’t think I’ve cleaned my fx5 for 2+ years now, but I also only do one 30-40% water change a week as well, so I may be on the milder side of obsessive tank maintenance. I like the aquaclears, and have them on a couple tanks, but I don’t think they keep up as well. By the way your fish looks awesome, a real stud. Good luck on your move, my roommate from Philly says as soon as you move to the northwest you are the biggest a-hole in the area. Sounds like the people are great, should be an awkward adjustment.
