    Hi everyone! I had some issues with setting up a grow bed's plumbing and it got me to thinking, in the interim, can I just set up a raft directly onto the fish tank? If it were any other kind of fish, I'd just go ahead and try it, but right now I have goldfish in the tank, which are notorious for…

    Goodmorning,I recently (system completed on 7/25) got my freindly style raft system going. I added nitrifying agents to the system to get the nitrogen cycle moving quicker.  However, I have no type of testing materials to see where levels sit in the water.  I introduced plants into the system on…
