I've made a few changes. I pulled the scwd because it vibrated the the pipes when switching. I could have reduced the amout of the flow to get rid of it, but that kind of defeats the purpose. I replaced the scwd with a t, but then it doesn't alternate.
I traded the scwd for the modded mj pictured above. last night I ordered another one which with the 2 I'll be at almost 60 times turnover within the tank.
Really, I would think that's enough, but I still want something that alternates so with the mj I ordered a sea swirl for the return.
That's it. The two koralias and the seio that were gonna be used are already sold which covered the cost of the sea swirl, so the wife didn't get too ticked at me spending 34 bucks on the other mj.
