yay Craig! those are some hefty net pots you've got there my friend. One thing I noticed though, in picture #3, are those drip line outputs? If so, I guess you are trying to just not have those extra 4 dripping into nothing? I may be wrong, but since they are all outputs you will be pushing water into each other at those points. Not sure how much pressure that could create to maybe get a problem, but it may be something you want to look at. I would say cut 2" pieces of the hose that are plugged shut and put one on each port you don't plan on using. As far as the pump goes, which one did you get? the 60 gallon fish tank ones are usually okay for a 5 gallon bucket, but for something that size like what you and I are using, you would want 2 of those or 1 like 100 gallon air pump or something around those lines. Looks good though man, keep it up!
