I have two of these
Selling 35.00 EACH, or grab em both for 60.
I used this on my 240 tank with corals, etc - has 4 outputs on back, hook up to powerheads, with 8 of em (both) I had a random wave making setup
you CAN set it up to whatever setup you wish, 2 on 2 off, etc etc I have the instructions (impossible to find) which will allow you to set it to your liking.
I moved from Minnesota, no room to keep a large tank, sold it off and will set up a nano sometimes soon.
Will meet up, or come to my home to deal 35 each or 60 for both cash please
I work downtown Austin, Riverside/SoCo
Thanks!
