return pump help

[FishyFishy!]

Yeah on most of my previous setups I ran Mag9.5's and I cant say anything bad about them. They're way cheaper than the eheims (nothing bad to say about the eheims aside from price). All of mine were quiet and added no heat to the aquarium. I currently have a Mag12 running my manifold, and its dead silent with no heat issues.

I have to add to the DC pump thing as well. They do have known issues with the power supplies and controllers. But that being said, I purchased a new power supply from an electronics store and both my DC10000's have been running perfectly ever since. They just need to tweak their power supplies and controllers a bit before they are truely suitable for the hobby.
