Comments: Seems as good as the old "Maxi-Jet" branded power heads w/ a couple new features such as an o-ring on the impellar housing. So far so good. Time will tell.

Perfect upgrade return

Comments: After getting advice from fellow reefers on whether or not to upgrade the stock return on my IM Nuvo16 I purchased this. The turn over rate of my tank increased from 211GPH to 295GPH. It is just as quiet as the stock return pump and only slightly bigger. So far so good.

undergravel filter powerhead

Comments: This powerhead is ideal for undergravel filters in 30 to 55 gallon tanks. A product like this was hard for me to find. I am using it for my fresh water tanks and do not need a powerful flow of water. 106 gallons of water per hour flow is just about right for the undergravel filter attachment. My fish will not be buffeted by a strong water flow. The extra parts inlcuded with the device were useful.

Comments: I have had reef aquariums for over 20 years so I have been around a bit. Point being that I have many different setups to this point. I was nervous to order a new replacement after my second MaxJet had gone out. I use these in my 29 gallon Bio. After speaking with a representative at the Depot, these were highly recommended. I just put them in a few days ago and can tell that they are good quality. Very quiet which is important.

Worth the extra money...

Comments: I was in the market for a new return pump for my nano and decided to go with the MJ1200. So far it has exceeded my expectations and is delivering a lot more return flow then my previous Aquarium Systems MJ900. The only concern I would pass on to others is that it does put out a little more heat at 20w. All and all, it’s a powerhouse that comes with plenty options and accessories. It’s definitely worth the extra money.

Comments: I had originally purchased Maxi Jet 1200 with my GFO and Carbon reactor. The damn thing was soooo noisy I could hear it from my back bedroom. I replaced it with the cobalt MJ1200 and it is now quiet as a church. I may buy a couple more in the future. : )

multi-purpose pump

Experience Level: Expert


Comments: Cobalt multi-purpose pump is a very good inexpensvie pump. I am in the plumbing business and I checked around to find a better price and a pump local. The only local pumps to do the gpm and head pressure I needed were double in price. The pump I use is in a 6ft head water fall and it does a superior job and is small enough to lay in the base of the water fall.
