Ever been in an anchorage rafted up with friends or in a marina and face embarrassment due to the aroma emanating from your boat after someone flushed?

Depending on your location, getting a replacement filter could be difficult and then, of course, in that location is the exorbitant price, typically around $125 for 1 unit. What if you could say good-bye forever to the high replacement toll and never purchase another filter over again? In other words, just refill the existing unit over and over and over again with elementary-to-find and cheap aquarium charcoal.

That is exactly what my friend Mark and I decided to do. We bought a couple of threaded PVC fittings, PVC primer and PVC glue, a box of charcoal, four"10 6" foam aquarium filter and some Teflon record. Total cost for materials was just under $20, the merely tools required were a hacksaw, tape measure out, sandpaper and a sharpie marker.

Here are the easy to follow steps…

Step 1 – layout all of your materials,
