    Does anyone know of where plans for a diy rdf can be found?

    That is just an example. Here is a video of a diy one

    CS; after researching this RDF a bit, I'm curious as to why you're interested in this type? What benefits over other types are you desiring? Certainly DIY would be less $$ but I wonder how/why a ponder would go this route over others.

    I see a system that is more costly, is going to require weather protection, need some sort of automatic 'sludge' dump/maintenance, and some worry re the lifetime of parts (seals, drum material, etc). Not to mention additional $$ re electricity to run.

    I love my RDF. However, if you don't prefilter with something like a sieve then the RDF will be cycling constantly (self cleaning). You might look into the DracoDrum (which is what I have) since you can install it into any number of cabinets including DIY but it still has all of the mechanisms in place to sense when cleaning is needed, etc.

    if you have enough plants, doesn't that take care of any nitrate problem? Seems to me it would...

    I just want to build one. The waste will just go into a bucket that's removed when full. As for having plants I am thinking on that route also. Bouncing bog filter ideas around in my head

    That's cool you want to get into the DIY part of ponding. I like doing the same, but don't want to have something that requires a lot of maintenance if I don't have to. I have other hobbies that also take up my time!

    Only a bog (actually, wetlands upflow filter) is the way I went initially. I ended up later putting in a mechanical prefilter as digging up the bog and cleaning it was a pita. Of course, if you shape the bog correctly, cleaning isn't supposed to be so onerous but still, the mech filter means I can worry less about potential clogging (again).

    The plants are for the nitrate buildup (and my enjoyment!) and the bog is for my biofiltering.

    Yes! (y)

    A lot of people that use RDF have no plants in their system though.

    ah, ok; gotcha. Thought I was missing something. Since I'm definitely a plant person, and plants need only thinning usually, I guess I went the right route for me!

    I think you use filter socks on your pond and I use filter socks on my sw aquarium.
    The test in the attached video demonstrates how quickly detritus breaks down into nitrate and phosphate in a filter sock.
    The relevant information starts at about the 3:30 minute area.
    The bacteria that break down the detritus are the same, the makeup of the detritus would be slightly different than our ponds.
    Having plants in the pond water would certainly help absorb excess nitrate and phosphate before it starts to feed nuisance algae.

    Thanks for the link, Mitch; it was interesting. I've had sw for a number of years now and only use the live rock as filtration. I do a water change of about 30% once every 4-6 weeks for my 90 gallon with 5 fish. I used to have an old fashioned 'outside the tank' filter but it was hard to get to for maintenance (I have my aq inside a shelving unit with not enough room to easily maneuver) and it seems to work.
