HydorKoralia Evolution Circulation & Wave Pump, 750-850 GPH, 115 Volts, Black

Excellent item but returned to seller for refund as not suitable for size for my aquarium

The product came late , didn’t include an English plug and was so noisy it made me think something was missing. I did rate the magnet fitting, so salvaged that and used it on the next wavemaker I bought. Overall thoughts - rubbish

First time using a wave maker. I was initially turned off by the high price of the brand recommended by YouTubers. I found this one and figured I'd give it a shot. Initially, I had some problema as it kept turning off. I took it out and it ran fine in the sink for an hour so I figured it was something to do with the tank. I may have had too much particulate matter in my tank since it was a new setup.I let the filter run for a few days and reinstalled it today. It's running great now. I'm amazed that it runs silently! It creates plenty of water movement for my 75 gallon tank, and I'm happy to not need bubblers. I'm trying for a quiet tank this time around!

I bought the 1400gph wave maker for my 90gallon 4ft tank and I must say this unit is very good, the build quality is great and best thing is that it is very SILENT! Have to bring my ear close to the wave maker to hear it. Initially I had some minor rattling from the plastic cage at times, but simple solution was to put a black snugly around the front and back part of the cage and that solved it. I tried several other lower cost Wavemakers of this size but ended up returning them all due to noise issues.

Not fancy, just works.Too bad this company went under, good product.
