I've read the thread. Wish I had before I bought it. For what its worth, my MP40 wet side broke at 13 months (conveniently right out of warrantee). $80 vs a new pump. I was mad about the MP40 breaking at the one year mark and essentially vowed to not buy their products anymore. Quite honestly, I had the same ridiculous problem with the magnets on the MP10 and MP40. I have 5 AI HD primes -- and I'm not happy about this Nero issue either. I have the older Maxspect gyre on the other side of my tank.
