Marineland Maxi Jet Water Pump and Powerhead for Aquariums

After a great deal of research as well as trying out several different multi-use pumps, I purchased the marine land Maxi jet 900. I currently have a 250L display tank (66gal) and a 20 gal quarantine tank. I wanted to average a 10-14x turnover rate and this pump fit the bill perfectly. In the larger tank, I set it up as a circulation pump, and in the small tank, I have it set up as a power head. I found the flow to be quite strong in both modes, and runs nearly silently. In powerhead mode, the venture works great and is adjustable (**** type air tube control) I did find that in my 20gal the flow was strong that the fish were struggling, so I turned the flap up and was able to get just the right flow in the tank to keep things comfortable for the fish. I love it so much I purchased 2. Also as a utility pump, I get a good 4' ~ 5' of vertical lift and has a decent flow as well. A must have... Sure beats the other pumps in the price range and even the pumps that cost 2x more.

Product was delivered very fast. Powerhead is being used as an internal filter by using foam and a water bottle and connecting it to the powerhead. Does great job of polishing the water. Plus it is very strong.

I put a 1200 in my 55gal cichlid tank they absolutely love it. Got rid of my air stone because the pump comes with an air valve for one mode. Works great super powerful and quiet. $50 at Pectco, thanks to Petmountain I saved a bunch. Need a good pump? Get this one.

The Marineland Maci-jet 400 helps my tank and is a very good product.

My power heads were eight years old and falling apart. Saw these, compared price and bing bang boom, I ordered two of them. Could not be happier with my power heads and Pet Mountain. Very good price, fast delivery.

Good pump for flow or filtration. Works great in bio-cubes and phosphate reactors.

I got 2 of these and they work great for me in my 55gal tank don't see how ppl are having problems with them and at this price you cant beat it.

Wow pet mountain is AMAZING! Great prices, great products, super fast shipping!

I have had so many power heads by so many manufacturers over the past decade, top of the line and basic generics... This guy is one of my favorites. Not only does this include everything you need to have a great laminar flow (wave maker, agitate water) but the included parts and connections have everything to make it a quite strong powerhead as well. I have a couple of the 400 models, and a couple spare as well. The max head says 3' or so, but it exceeds that- and few pumps at this price point will deliver that performance. Using it as in laminar mode often creates "mini-tornadoes" that spiral down to the unit...It is very strong, quiet, the suction cups could stick a little better, but that is no deal breaker. I noticed that a part was missing from one box and they were happy to quickly send the part. No issues, has been running non stop for over a year and a half, and still looks new. In no way is the unit cheaply made, everything fits tightly and holds its position. A+ in all respects.

I bought this to help circulate water in my 55g before I got the C-530 canister filter. It had plenty of power in my 55g, probably even too much for my application. The three suction cups that hold it in place stays in place and I never have to press it onto the glass once its in. I've purposed it to do an internal CO2 diffuser, diffuse CO2 directly into the input which produces super fine mist of CO2 bubbles. I've since used this unit for changing water attached to a 25' gravel cleaner/water change kit. Works great in any application I've put it to. The price is right too.
