Hey guys, I bought a SHP reg for my RT Mag, and I had two of my tanks hydroed and I figured I would just have the shop install my new SHP reg onto one of the tanks that I brought in. I just got a call today from them saying that the reg was a bit too large to fit into the tank. Have any of you had any similar issues? Im going to bring in my other tank and see if it will fit on that one. Kinda strange I figured that all of the HP tanks would be threaded the same...
