i was looking for a little more "exact" flow, so this is what i came up with..
in the left of the pic, there is the spray nozzle that comes on the IM Lagoon. simply break it apart and snap it to the 1/2 line. (like side already attached)
initially i ordered 3/4 inch Ball/ FTP threaded to go thru the bulkhead wall... doesn't work
i'll need to reorder the half inch with half in "T" to do what I initially wanted to..
if you would like to do this design, just order the 1/2 inch bar and the ball coupler (middle of the bar) to join the 2 together
I found the best price and selection at modularhose
I will order 2ea 1/2" "T"s to run the bar across the back
i'm also going to feed a line to my HOB fuge and get rid of that whole pump setup (I need low flow for copepods)(the tank supports a Blue Stripe Pipe
