A Community and Forum For Aquaponic Gardeners

Fish-less Systems

Information

This is a group for people who have any kinds of fish-less systems, but yet are not doing classical hydroponics. Where we can share what we have come to find about making-home made nutrients, oganic-hydro, pee-ponics, worm tea hydro, bio-ponics, home-made buffers, water chemistry or anything else that is perhaps inappropriate for fish. As well as experimenting and sharing results for things that might be alright for our aquatic critters.

Comment by David Schwinghamer on February 28, 2012 at 1:31pm: What Im having trouble understanding is when I was using my spray system in a plastic bin with grow cups filled with hydroton was working so well. I guess these pots gave the system enough bio filtering to be successful.

Comment by LogicalHydro on February 28, 2012 at 1:27pm: David,

Vlad has a good point. Add some bigger aggregates to entrap larger air pockets. Preferably porous stuff like expanded shale or lava rocks

Comment by David Schwinghamer on February 28, 2012 at 1:25pm: How about coir with hydroton in two places, in the beginning of the first tube and also in the liquid reservoir?

Comment by Vlad Jovanovic on February 28, 2012 at 1:08pm: Hmm...I've started using wet coir (mixed with vermiculite) to create anoxic zones (don't ask :), it has horrible air retention properties. My vote would be for something like rocks, (or Hydroton, Lava Rocks, whatever) and fresh worm castings if you have them. My opinion is that soaking wet compost and coir alone wouldn't really have the air retention you're looking for. It would do you some good to break up some of that compaction by at least adding some rocks to the mix.

Comment by David Schwinghamer on February 28, 2012 at 12:52pm: I stuck a panty hose leg full of compost and coir in the beginning of the first tube, is that a good start?

Comment by TCLynx on February 28, 2012 at 6:00am: hay Carey, ya use what you have. However, I would chose rocks over perlite personally. And I make my own blocks with peat, coir, and worm castings instead of using rockwool. I could use different materials to make the blocks but those are what I have.

Comment by Carey Ma on February 28, 2012 at 4:16am: OK OK so its a pain sometimes...and maybe not good in AP but I still love it over any other medium. Dummy me. Ooooppps..that's the only thinkg I can get here. I could only dream of using hydroton or rock-wool or any of those fancy, first world mediums.

Comment by Eric Warwick on February 27, 2012 at 8:45pm: TCLynx: Can I edit that statement. I would avoid perlite ~~in aquaponics~~ . It tends to get into everything and is nearly impossible to get rid of.
