cali reef, i had originally wanted an Eheim pump, but had trouble finding a vendor with stock of the size I needed, so i went w/ the Mag 7. I was surprised to see that they used metal screws for it when I unpacked the thing too. I thought to myself, "wait a minute, doesn't saltwater corrode metal..."
After spending so much time on it, I am completely chicken about trying to drill my sump for a 1" bulkhead. If I cracked the sump, I would have a breakdown right then and there. I know it's the better way to do it, but this is going to have to suffice for my first run at things as a newbie! I nearly had a heart attack when I scuffed the inside wall of the sump w/ a cutting bit of my Dremel last weekend while I was squaring off a PVC pipe leading to the skimmer. The Dremel hadn't quite stopped spinning by the time I bumped the glass wall with it. The whole bit dissintegrated into a thousand little pieces, but thank God it didn't break the sump wall.
