Hi Victor,

The MJ 900 you are using, is it been run as a external pump not submerged? Is this possible? I thought these powerheads needs to be submerged in water for them to work? The plan for a purifier type reactor suggest using a mag three. Thanks!!

Hi Rachel,

Sure I'll keep you posted. But I can't see myself starting on the project until I can get my hands on a co2 tank. Talk to you later!

Hi,

Unlike many other powerheads, the Maxijets have an O-ring seal around the impeller housing and the powerhead electromagnet. The o-ring prevents the powerhead from leaking and improves overall efficiency. It also allows the powerheat to operate in a non-submersed operation. Similar techniques are used on larger pumps such as Mags and Little Giants.

The Maxijet was my choice because I wanted an inexpensive pump that I could through out every three years. There is a lot of grit and calcium sand in the circulation path of thr reactor -- this tends to wear down the impeller...and sometimes entire powerhead. This is the case for the cheaper Mags and Maxijets. The Eheim pumps are...well...indestructable...so I would get that one instead. You'll notice that many of the heavy duty reactors use Eheim..including Canreef's. I think Mags are $60...so a $100 Eheim is a better investment.

- Victor.

Thank You Victor for all the info!!!!
