I definitely don't do what I recommend to others at all. I have a Laguna pond pump on one of my tanks only because it was 20 bucks used for 1 week, cleaned l, and has a 17ft head height. Seems to be non corrosive since October. The mfg later informed me it was all stainless steel so a long as you check on pumps' materials you can find some hidden jewels as well. Not that my Laguna is a jewel but it takes water from my basement up to the fish room. I could probably use a nicer one or move the sump closer to my tank and have better flow. It was just one of those weeks when my good pump died lol.
