Even though it was not designed for the Fluval Spec 16, it does work! There was a slight problem with it getting stuck in the hole if you push it too far down. To fix this, I superglued a small piece of plastic to the hood preventing the cover cap from getting jammed. Fabulous build quality. Would buy it again!!

Fits well, looks good.

Fits perfectly. High quality. Thank you!

Absolutely amazing engineering. It was thought out all the way down to wire management. There was heat shrink and a very sleek design on top. It's very lightweight and to be honest a tank changer.

My tank was hovering around 83 for the last 2 weeks in the middle of Alaskan winter. No lie I added this modification and it's down to 78 within an hour. On top of that the oxygen injection increases my pH which in turn my corals pop! My fish aren't lethargic anymore and are eating but they haven't eaten in weeks.

This product shipped to Alaska in under 2 days. I can't stress enough how amazing this product is for the 13.5 Evo.

Worked out perfect for my tank.
