I currently have a HOB CPR Aquafuge.  It's the medium size and the older model that uses a siphon for the outlet.  Right now it's hanging on my 65g and I'm wondering if it's worth the hassle.  I've had a number of issues with it and right now it's covered in algae and cyano.  I also have 4" of sand in it.  I read on WetWebMedia that it's basically a "puddle" and doesn't serve much of a purpose.  Should I remove it?  I've also thought about taking it off, cleaning the sand out of it and running it as nothing more that a cheato farm.  I want to modify the outlet to the newer style that's gravity fed rather than depending on a siphon.  If I can do that my water level issue will be taken care of.  I'm just wondering if it's really worth fooling with at all.
