Backyard Aquaponics
A place to discuss aquaponics

I think we are getting a bit pedantic here. Surely a radial flow filter in aquaponics is just to pull out some of the solids not all, so a flat bottomed filter will do that. Mine does
A cone bottom would only be needed with an aquaculture setup
I know you guys like to build and tinker with stuff but dont think that a cone bottomed, all solids removing filter is needed in an aquaponic setup

Spot on Mantis!!

I have a cone base on mine as i used water bottle but its not essential in such small operations

I've been trying to find this scientist that observed water in nature - saw a documentary on youtube about him. Can't find it anywhere, but It was in reference to the conical inside bit - better to have it smaller diameter at the bottom If I remember.

gday all
i just took a couple of photos of the solid build up
it only been going for a few days now
all that crap sitting on the outlet
we are very happy with our little buildwe will give a weeks run and see whats in the bottom of the drum
cheers b&v

Has anyone thought about incorporating an RSG filter into the bottom of an RFF? I like the idea of having a controlled area for anaerobic action too. I good way of making iron bioavailable.

Ron,
Didn't know what an RSG was until I googled it about a minute ago. Looks like a pretty simple idea, don't know what you mean by putting it on the bottom of the RFF. I would almost do an attachment on the outflow of the RFF and then feed directly into a sump where the water could then be pumped to all growbeds simultaneously. That would be the easy way.

Now that I'm thinking (ouch that hurt) about it a little more I'll leapfrog off your idea. If you had a wide enough bucket to do a 4" outflow downpipe and drilled the outflow hole into the bottom instead of out the side and then proceeded to put a 4" to 1" or 2" adapter after the downpipe exits the bottom, it may just work.

Explaining it in a more clear process.
1. Water comes into the side of the filter and makes its bend upwards.
2. Solids discharged and knocked out of suspension.
3. Cleaner water fills over the height of the 4" standpipe on the outside of the larger inlet sleeve.
4. Calm water makes is way through the RSG until out of the filter
5. Filtered water sent to sump via 1-2" pipe.

Could use a little work, but I like where this may lead. Thanks for the idea Ron!

mine was build from scraps around the house so it cost me nothing; the center cylinder was a beef jerky container. I'll see if I could take a few shots of my setup later today and share.

So basically filling the bottom with sand?
i had that in one of my fishtanks, people said it was bad.

Just a quick interruption...can someone tell me what RFF and RSG stand for? I keep seeing them and google wasn't friendly to me during my search

RFF= Radial Flow Filter
RSG= Really Smart Guy (filter)

this is my RFF

Just a random thought; a radial filter (I prefer contra flow) could be differently designed.
This one has some possibilities
There are two (well more) types of crap in a system from the heavy, light small and large. Water enters the up pipe and then has to flow to the bottom against an up flowing stream. The downward pointing cone will tend to only let fairly heavy solids pass it, collisions between small floaties and the heavier smallers will cause them to clump. Lets assume some will continue to float. If the through supporting pipe was cut out on the top and an end cap was placed on one end and a tap/valve was placed on the other wouldn't you also be able to remove crap from the top?

love it what a great build
this is what this thread is all about just the ideas [url=http

here is one i have made for my parents, in the photo it is a swirl filter but when it is installed it will be modified to be a RFF just like mine

How have you plumbed the pipe through the IBC, Iceman? Slaz?
