ReefWave 45 Flow Pump by Red Sea

The ReefWave series of flow pumps are based on Gyre patented, cross-flow technology. They provide optimal water flow for corals, regardless of their position in your aquarium. The ReefWave is available in two models, the ReefWave 25 & the Reefwave 45, which can be used alone or in multiples to suit tanks from 2 feet up to 6 1/2 feet in length. Each pump includes its own controller to allow for both local and remote control via WiFi and the Reef Beat App. The user-friendly Reef Beat app also allows you to sync multiple pumps and create your own programs with custom wave types and intensities, which can be precisely scheduled-- along with defined "off" periods for feed mode-- for more advanced controllability. The ReefWave pumps have also been designed with ease of maintenance in mind-- they include color-coded parts which make assembly and disassembly a breeze. ReefWave flow pumps are nearly silent, smart, powerful, and easy to maintain; making them ideal in a wide range of reefscape aquariums.

Great Pump - Connectivity and Controller Issues

Pros: Quit and powerful

Cons: Fragile controller, wifi/app are difficult at best. Customer service is unbelieveably slow.

This is a nice pump. Its dead silent and provides tons of flow. I have it on a 4' tank running random at 30% and its great. Unfortunately, I can't get it to connect to WIFI, so using the app it not really an option. No problem, it has a controller. This controller is fragile. It was mounted under the stand and I can only guess it got splashed during my skimmer break in. The 4 other controllers under there are fine, but this one shorted out. It took 3 weeks of emails with RedSea to get a new one sent out, and they're charging me $75 for it, That is after doing me the 'favor' of reducing the $120 original price. All I can say is if you get one of these, be careful about where you mount your controller, as it doesn't seem very well sealed, which is odd considering it is intended to run in a high moisture environment. I'm going to get another pump to run on the opposite end of the tank, but I think I'll give one of the competitors a try, the experience couldn't possibly be any more frustrating than the one provided by RedSea

Awesome gyre

Pros: Even strong flow through entire aquarium

Cons: None!

Bought two of these for my new 525 XL. They have to be one of the best on the market. I run mine on random 30-40 percent and I got amazing Flow all around my tank and they are beyond silent.I highly recommended the reef wave to anybody that wants a good gyre pump.
