Brian, what kinda carbon filter is that.. I do see a potential problem depending on the type.. for eg. if it is a "carbon block" styal filter is should be ok but they can cost up to 20.00 each.. if it is a GAC (granular actavated carbon) styal they have a very high amount of dust in them and if I recal right most instructions say to rins them for like 5 min befor use to remove the dust (thease are you commen 5 to 10 buck ones)
the problem comes in that if you don't rinse it you will be sucking carbon dust into your tank.. and depending on the quality of carbon used (and I can pretty much be confident in saying a 5 or 10 buck filter will be using a low grade as all it is for is chlorine removel not organic compound removal) it could have negative effects over time.
I think you would be better off building a PVC filter that you can replace the carbon in and use small amounts of a marine grade carbon that you can change once a month or when you do your regular skimmer services.
then you could just use a 1 micron poly filter from HD for 5.00 and have the carbon chamber inline.
but the idea is a good one and I will be loooking into something like I just described.. Thanks for the idea
Steve
