man i was soposto nap before coming into work tonight, i started changing out my return pluming at 4 thinking it would take me an hour tops, After i pulled out my old and put in the new that i already had glued and ready, it turns out the tham pump decides it loves the PVC so much more that it flows way better i mean like double what it useto and my overflow box cant keep up, Even using the manifold i had mad going to my reactors it still flowed to much. SO i had to run to Lowes and get a ball valve. Installed that and everything was good with the flow, then i realize i have a leek on the reactor. Took me a freaken hour to get it to stop leaking. Ugh im glad i got better flow now. Im actually thinking of adding another overflow box so that i have one on each side of the tank.
