Hello First Off. I am brand new to the Aquaponics field and I must say am very hooked. I was brought to this site through Olivers aquaponic 101 threads and I found them to very very informative and very helpful.
However, I was wondering about the depth of the GB'S.... Oliver said it needs to be a foot high. I have four trays 3x3 that are a little over half that (6.5 in.) I am wondering if I might get that to work still. I plan on using a 275g IBC for my FT, and I was planning on using Pea gravel as the media in the GBs. I also want to have a fifth tray that is 4x4 also about 6.5 in high to be used for "deep water" rafts (Maybe a bit ambitious, but I already have the trays on hand... and this is the begining stages of planning here ^_^) I will submit plans as I have them drawn. I appreaciate all forms of constructive criticsims and positive advice. Hope this finds everyone well!
