This is vary similar to what I have now and may be able to modify it work like yours. Can you add more detailed pictures and setup info to this thread or PM me which ever you think is best.
I am getting ready to get some blocks like you have as well so let me about how many you have. I posted questions about them to make sure I was getting a good dear rather than just buying some new blocks.
I am curious to see how the water flows from your tank to the barrel and filter etc.
Looking forward to your additions to this thread.
Also you are working with male Tilapia as well correct? I was just curious if you had any spawn if not the case. Also what temp is your water and do you have issues keeping it warm since it is not in the sun?
