Curious about this. I think this will be the next rhelm I venture into to see what I get. I've always had some type of filtration on my tanks.
Well my QT tanks are filterless :lol:
Actually, I believe this is mentioned in Walstad's book (which I highly recommend). She discusses biofilms, and how there can be communities of both aerobic and anaerobic bacteria in the same biofilm. Also, the soil contributes to this, with the deeper areas having limited oxygen, and fostering anaerobes that will remove nitrates.I talked to a bacteriologist this past summer about bacteria in freshwater vs. saltwater. We discussed the fact that in the saltwater world they often relie on bacteria to do the filter utilizing both aerobic and anaerobic bacteria. He pointed out that ponds and lakes in the "real world" utilize the exact same system and that there is no reason that it shouldn't work for freshwater just like it does for saltwater. I haven't personally ventured there yet, but it is an area I'm planning to dabble in in the future.
that's pretty cool looking. When you have to get inside to the tank to clean it, is it a pain to remove all those emersed plants from the top without making a mess?Hello james...
I run a tank with no mechanical filtration. It's filtered by emersed land plants. Attached is pic if you're interested. The plant roots take in the toxins produced by the roughly 75 Fancy Guppies in the tank and return pure water to the tank. I just replace a little water that's lost to evaporation. I do have to trim the plants sometimes too. Maintenance takes 20-30 minutes a week at most.
