In all honesty the APS filter hasn't been on the tank for so long I don't really remember what it was like - so I think it was..fine? Flow probably not as high as advertised and not the easiest to prime/get going but for the price more than adequate. It didn't come off the tank because it broke or anything - I just disconnected it during the temporary move to a Rio 125 and never put it back on and now it's in storage somewhere. I may have broken the inlet too now I think of it...Can I ask you how you get on with the APS External Filter? I read that you had a right battle with it at the beginning.
