    I live in the Caribbean and we have to import all of our materials. I am in the works of designing/ pricing out a commercial aquaponics system and would like there to be a large raft component and was wondering if anyone had any suggestions on raft materials? I am currently using 1" dow blue board as I can get that from our hardware store but if there is a cheaper alternative that I can import from the states that would be great. Any suggestions?

    I also live in the Caribbean, Curacao. I find that grapes are imported in foam container consisting of two half's. I use these to make 2" holes as use them as floaters/rafts. Works perfectly and I get them at the supermarkets for free. The lit I use without modification. The bottom part has more foam material and drift higher so that the bottom of the net pot does not touch the water. So I cut 2 cm off. I'll post some pictures tomorrow.

    Hi everybody I have been gone for a long time. I had things going close to cycling then a job took us all over the western us. So now I'm out of the loop. Now I have set up a raft 4'x8'x7" and have it cycling without fish I added ammonia and waiting on the test kit to arrive. My question is what is, can I use coconut fiber in my net pots? I have about 450 us gal cycling.
