Pic of the week poll
I find that people that make fun of us keeping fish are people that don't have any kind of hobby and if they do it's one that don't require them to do much of anything to maintain it. I'm in my late 50's and most of my friend say they don't have time for anything like that but like me most of them are retired and have a hard time being alone because they don't know what to do with themselves. I do find that people that have other hobbies that require time and some money totally understand the passion and the amount of money we put into this hobby.
I have and use both. My Tetra EX45 is used as a secondary filter to a canister. I'm not sure why you need to remove one of them. I understand you have more GPH than you need but it's not going to hurt anything to leave it on there. But if I had a choice I would go with the AC.
