UniclifeAquarium Wave Maker for 120-300 Gallon Fish Tanks 3400 GPH Adjustable Circulation Pump with Controller and Strong Magnetic Suction Base Submersible Power Head for Fresh and Salty Water

I bought 2 of these for may 200gal Saltwater Tank 3-4 years ago. I have never cleaned them and they are still going strong. They are powerful so choose wisely. Good product!!

I’ve had this running for 3-4 years non stop first in a 125 mixed reef and then in a 210. Crazy powerful. Never cleaned or maintained it, about to buy a replacement just because this has lived a good life and by now it’s gotta be leeching something into the tank. I use the wave mode constantly, even when lights are off fish don’t seem to mind they find a rock to sleep in. Great buy and value.

Used in a 125g with some sand. Pushed so much water it dug up my substrate! Has a controller with a few presets so that’s cool. Definitely too big for my tank. Easy instructions for instillation and built strong with thick cabling. No added noise besides the water flowing sounds.

The media could not be loaded. It's just day one after installing the W-40, but I'm super impressed to this point. I've got a 180 gallon, six foot tank, and running it on 40% power, it's more than enough movement for what I'm looking for. It's kicken up the detritus and moving it to my two FX6 intakes. Anxious to see how much cleaner the water looks after it runs a few days. It's whisper quiet too.Also, I did notice that if it's to close to the surface, it will cyclone the surface and you can actually hear it sucking. This happened at 40% and I had to drop it a few more inches from the surface to get that suction noise to stop.I researched and studied for a few weeks before I made this purchase. I'll bet I looked at roughly 50 or more wavemakers and am glad I got this one! The price was also a huge bonus in my mind! Can't go wrong with this one imho.I am beyond happy at this point and will update this review after it's had a chance to run a few weeks.

For the price this is a great item. Initial impressions were build seems sturdy and easy setup. Very nice magnet attachment. This unit does not add any noise to my tank and the adjustable fan speed and wave option is a nice feature. Oh, and it moves alot of water, too much for my 45 gallon tank.

Liked: powerful on max setting! Control center is well made and works - many features. I also liked the feed mode and the nighttime reducing flow option.Disliked: none

The media could not be loaded. Stopped working after 3 months of use. No way to contact support.

I would rate higher if not for too strong of a flow in the lowest setting. If you are looking for serious water movement as others have stated this moves some serious water. Wave function found to be the best setting as the other settings were difficult to gauge any changes (both active reef and "non active"). Pointing pump just abut 80 Degree from bottom of tank w/ lowest setting seems to create a nice flow for our setup (75 gal). When compared to MP40 Vortec. It flows more but as noted not the same level of tuning, nor as refined, but also no where near the $$$. Quiet, moves water, may take a few tries / placement, and angles for optimal flow but seems good. As others have noted picking up sleeve/guard as did have an encounter with newly picked up anenome that had not fully attached.
