Fish-less Systems

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.

Warning... Much of what may be contained here may, or may not be a good idea to apply to a system populated with living, breathing, happy fish, crustaceans or any other aquatic life. So be smart...

If compost tea stinks, it was allowed to go anaerobic and that is not good.  Just a little stir is probably not enough unless you goal is to simply make yourself gag by stirring up the stink.

Make your next batch using an aerator and use immediately, don't let it sit around after brewing.

@NTS Last I checked compost tea is not a living organism. However its has microrganisms in it that make it more potent than the nutrients it contians. What you've got is some anaerobic microrganisms that make it stink. You could try stiring it, or putting an airstone in it, or you could just dump it in the backyard. Try to keep it oxygenated next time, or use it quickly.

I think I might have found the problem. My compost tea stinks, I just read this means it is dead. Will stirring create enough oxygen to keep the tea alive?

Tell us more. Dual root zone method, soil or media, AP, flood and drain? Are you using only compost tea, or compost tea on addition to something? Are you using the tea for watering or foliar spray? How do you make your tea?

I am using compost tea, and my plants are yellow and not growing very much.

Well I just finished a video on my system. It's a little long but hopefully informative. http://www.youtube.com/watch?v=IEFyMQvLOJI

Feel free to comment, thanks!

I was gonna say, the aged urine in a bottle might spike a pH up to 9 but once diluted into the system I wouldn't expect to see more than a tiny bump up in pH which will quickly come down due to the nitrification.  My pee ponics system pH came down just fine and continued on down until I buffered it.

Comment by Meir Lazar on March 22, 2012 at 2:53pm
I just tested the PH again and either it dropped down to 7 or I contaminated my first test. Looks like I won't need lashes or leaves after all :D
Comment by Jon Parr on March 22, 2012 at 2:05pm
Replacing lashes? Silly autocorrect. Replacing leaves, I meant. Yes, bummer about the dark water. And it gets so dark you won't even know if there's fish in there. I don't mind that on some tanks, but some I'd like to keep clear too. Wood and sawdust work too, to naturally acidity, but with the same effect. Carbon dioxide also works, bit it's hardly a natural way to go, and fish don't appreciate too much. I used to have no difficulty keeping pH down, now I can't keep it down, and I'm not sure what has changed. The media is the same, and pH in all systems is 8.0-8.2 unless I actively fight it down.
