Backyard Aquaponics
A place to discuss aquaponics

Ok people. I have decided to work on small rly small ap system just to get a grip as how this thing works...couse there isnt one in close range of my domain wich is Croatia..i'll get like 150-200l tank( drill holes and etc) make an tack for floating raft. Now is it better to use some media (can i use normal rocks, gravel) or floating raft with holes in it and pots with some media. Is 30cm enough of grow bed depth? The gravel i am seeing people use on vids isnt to find in Croatia. Extruded polysterien with 50mm is enough? And how powerful waterpump is enough?

Did you try using the search function for Croatia... there are quite a few posts you might want to read. Click here: http://www.backyardaquaponics.com/forum/search.php?keywords=croatia

David,

This previous post are almost all from me.
Institute for renevable energy did an project and build small AP and they are researching why is pike perch so hard to raise in ap and what plants grow best in what conditions. And that is all from ap in Croatia

Sorry, I knew I had seen posts on one of the forums about aquaponics in Croatia... I didn't realize you were the only one. I have seen some of the CCRES info, also.

I know. Have read what they did. Their artical was helpfull and i conntact them but they werent very helpfull. Must be a mem of their organisation than they will share opinion with me...

try reading this - it covers most things and gives the theory etc.
