sumphead,
thanks for the link to your instructions. was that for an entire wet/dry filter or is that a drop-in to enable using an existing aquarium as a sump.
i am considering using a used aquarium as a starting point (as others on this forum have eluded to) and just inserting baffles. in your opinion, is that an exceptable way to go. also, how do i know what size of aquarium to use as a wet/dry filter/sump. i will be using it for a 75gal tank. also, what capacity return pump would be correct for this size aquarium.
oh, as far as a basic design, i have something in mind, but am still researching to make sure i don't get "builder's remorse". actually, your opinions to my questions will help me finalize a design that i will be more than happy to pm you for further suggestions.
