Cobalt Aquatics Mini MJ 404 Water Pump - 106gph

Worked great as a replacement for my petsmart Topfin 2.5gallon Aqaurium. It has plenty of flow and better then the factory one. The tubing is different but I made it work. It is also a snug fit but fits in the same compartment you’ll just need to move the output nozzle out to get the pump down then place it back in easy.

This small water pump is used in many counter top decretive water fall applications and was originally sold under the name of Mini-Jet by Aquarium Systems. A product that is very well made and will last for many years. Unfortunately it appears they went out of business. Fortunately it appears that they were purchased by another company called Cobalt Aquatics and are selling the pump as MJ MINI 404. It certainty appears to be identical to the original in every way. Hopefully this one will last another 12 years.

Works flawlessly in our handmade water feature.The pump is extremely quiet.

A bit awkward to work with but otherwise ok

We use this pump for a water fountain / cat water. The current one (same model) has run continuously for at least 10 years, but is showing some signs of failure. We just wanted a replacement on hand.

Good, quality pump. Is super quiet and is still going strong.

I needed a small pump for my aquarium uv light. Something adjustable down to approx. 50gph. This pump fit the bill for me. I used this pump once before and after many years it's still the same pump. Unlike so many others that are bought out by other company's and cheapen them up.Yes I'd buy it again!

Perfect replacement for Marineland 5 gallon portrait aquarium. Fits perfectly, same pump speed as OEM pump that came with the aquarium. You might have to reverse the tubing for a better fit on the pump and apply Teflon tape at the hard connection piece at the top where the tube fits into the tank flow apparatus.
