one thing that has become confusing to me is biologically filtering nitrate. after hearing about novak anoxic filtering and now about pondguru's anaerobic filtering, are they the same bacteria? they seem to take the same amount of time to establish. anaerobic nitrate filtering seems like an easier setup. easier than both of those seems to be a bunch of emersed plants 🤷‍♂️

sorry, I meant that I want it to overflow out of the top. I could cut a section of of the top rim that would be lower than the rest and would overflow there like a waterfall.

im planning one out now and was considering how i want to setup the filter. it would use bog type filter where i just pumped water into the bottom of the container that hold the plants and pack with pea pebbles. i could maybe add a spray bar type attachment to the end of the pump hose on the bottom of the container to try and evenly distribute the water flow. i would either cut out a lip out of the top of the container so the water spills out of it or have it so the whole container is submerged. do you see an issue with this type of filter?

im about to setup a 30G tote deck pond for two fantails because they are currently in a 10G tank. i was wondering about the safety for fish of using new cinder blocks in the tank to prop up the plants. i didnt come across any solid information either way. mostly people concerned about what they are made with and if they affect pH.
