So, I bought 2 chinese powerheads in December, and I'm now down to one. I was talking with Greg and Tethered_Limbs in chat the other day, and I was mentioning that I was interested in an MP40. Well, somehow they got on topic about the surge tank at MCF. I love DIY, so of course I asked questions and started searching how to make them.. Turns out, they are pretty simple to do! I have an Iwaki 70rlt, so creating enough lift to a couple buckets won't be an issue, if I splice into my return. Here is the first run with scrap PVC I had laying around the house. It's 1" pipe, I plan to swap that out for 1.5" once my new bulkheads come in. It's just one for now, but I'm going to run one on each end of the tank.
