bio-media on the floor of a raft system

[Daniel Gunloche]

Hello all,

I'm sure this has been discussed before, but I can't seem to find anything on it.  Could gravel media (let's say 8" deep) be placed on the floor of a raft system for biofiltration purposes? Would there be enough aeration for it to function properly?  It sure seems like this would provide a whole lot of surface area for needed biofiltration in this type of system.

 

Thanks,  Dan

The Aquaponics needs more filtration than that to keep the water quality high but if you have ample filtration in the system elsewhere a feed that can operate separate to say feed just the strawberries would be fine.

Hi TCLynx - I don't know if you are aware that you have replied to this question before, has my question repeated itself in the forum when it turned to a second page?  Thanks  Dan

Quite possible.  I have trouble keeping track sometimes.

Well, Thanks again!  I am amazed at how diligent you are on this forum!  Dan

It comes in fits and starts though.  I don't know that I will have as much time or access to the internet for the next couple weeks.  But when I can I like to do what I can
