Charcoal filter?
Xref: kermit rec.ponds:147229
Intro: I've been lurking for a few weeks and decided it's time to take the plunge. My son was given permission to catch goldfish (net) at pond and came home with 6 very nice comets, ranging from 4 to 9" length. They have been living in a 37 Gal tank (too small!) while we build a pond for them. We purchased a 150 gal preform and have put it in the ground. I bought a 1400 gph pump at a fish auction and am starting to build the filter. I have decided on a 55 gal barrel filter with an up flow gravel bed and plan on having WH floating in the top as a veggie filter. I know that charcoal briquettes are only sawdust and glue and some sodium nitrate to speed up burning, and given this composition, are totally unsuitable for aquatic use, however, my local food Coop sells natural chunk hardwood charcoal with no additives. Would this be effective as a filter material, at least while cycling, and in the future to clear meds, etc? Jeff Lowe |
