Comments: Excellent build quality, only gripe is a knock as one of the K4's turns on, but thats all...oh and the brightness of the LED's on the display are phenomenal... No guessing games with this unit as its straight forth and easy to use...

Comments: There's not too much to say. Hydor makes awesome water movement devices. I trust Hydor 100% and only use Hydor for water movement in my tanks. The ONLY drawback to the "Nano" version is that even at full power, the Nano powerheads are weak. For a 10 gallon or less, they're perfect. I actually had to step up to the Koralia 1 powerheads. Now the water movement is GREAT! If you have anything above 10 gallons, get the #1 powerheads.

Comments: I really like the Hydor. Its easy to use very quiet,and moves the water well. I have one at each end of my 180 gal. saltwater tank. I would recomend this product to a friend.

Comments: Very nice wavemaker. You can adjust the max and the min of both pumps. It has night mode as well.
<br />Now it can even handle big pumps, if you want.
<br />For even greater flexability and more water movement, people might want to consider spending a little more and gettig the 4 way wavemaker. It not only does 4 Koralias, but the computer software and ability to program it are much more sophisticated. The display is nicer too. Costs more, but as most of us have seen, it is better to get the good stuff from the outset. It would not be worth getting the 4 way for a small tank, I would say for tanks a least 100 gallons or more.

Comments: Not what I expected, was expecting more of a wave effect. Wish the minimum setting was almost an off position. With one side still blowing at a min and the other side full max the wave effect is not as great.
<br />
<br />Plug and play operation from the box, easy to get going
<br />
<br />Fish love the flow this gives rather then a constant flow from my previous Koralia's. The light sensor is a must.. along with the feeding mode is great
<br />
<br />Overall a great built product, I do like it better then two standard Koralia 4 pump.

Comments: This system is an improvement over the stand-along Koralia pumps because this system cycles the pumps silently. The stand alone pumps would make a hideous clanking noise when starting up. Also, you can adjust the minimum and maximum power levels of the pumps. However, the pumps do not cycle on and off; just high and low. The range of adjustability of the minimum setting should extend down to 0.
<br />
<br />This also makes the feeding feature useless. The pumps are still blowing water around (the feeding mode turns both pumps to low), which scatters the food in all directions. You have to shut the machine off, which is just about as easy as hitting the feeding mode button (with the exeption of allowing for the possibility of forgetting to turn it back on).
<br />
<br />I also do not recommend Koralia 4's for a 48" tank. I think 3's would work better.

Comments: I just got my Hydor Wave Maker 2 with 2 K4's this week and I think it is really nice. It won't make a wave like the tunze wavebox but that is not what I bought it for anyway. It provides a nice wide flow and alternates from one side of the tank to the other. In my opinion the wave action that many waveboxes create is not enough water movement for a tank by them self, you still need to have laminar flow. The Hydor Wave Maker 2 simulates a reef crest which exactly what I was aiming for. It provides laminar flow from one side and then at a predefined increment (I have mine set at 13 seconds) it switches to the other side, then back again and so on and so forth. This is really a much more useful feature IMO than the function of a wavebox or similar device. With all of that said the Hydor Wave Maker 2 with 2 K4's is a very nice product provided you buy the appropriately sized pumps for your system. IMO the K4's at 1400 GHP are only sized for a 65 or 75 gallon tank. Anything much bigger than that and you will need to get the koralia magnum pumps. Remember when calculating your GPH requirements that only one of these pumps are going to be on at full power at a time.
<br />
<br />In conclusion the Hydor Wave Maker 2 is a great product (so far) just don't expect 2 K4's to be enough flow for a 120 gallon tank because it won't even be close. You will need to look at the Koralia 5-8 Controllable Pump/Powerheads.

Comments: Overall, I am very happy with the product. My only complaint with the wavemaker is the feeding mode. When the unit is in feeding mode it will still run the pumps at the minimum pump setting which in the case of the Koralia 3 is 370gph per pump. So in my case I need to turn the unit off for feeding. Everything else is great!

Comments: Great Product! Pulled the parts out of box, put together components, set dials, and was in business. Well built equipment. I have the light sensor which works great to drop to slow speeds in the evening (works great). I just shut it off to do feeding and it starts back up right where it left off on power up (it also has some button to push for feeding mode). It would be nice if the slow speed was able to go a little slower.

Comments: I was torn between the Hydor and the Vortech wavemakers for my new 70g reef show tank. After reading reviews on the noise issues with the VorTech and listening to a member in my reef club about his disappointment with the VorTech, the choice was easy. I am extremely happy with the Hydor. Setup is simple with really the only functions you will need. The low voltage pumps give off almost no heat and the cords are plenty long to remotely set up the controller. I purchased the optional "electric eye" to lower the flow at night and it worked perfect. I have the tank set up in my living room and did not want to noise issues with the VorTech. The Hydor pumps are silent. I highly recommend this product!

Comments: i love t and same with my corals that open more and seem to be doing better.I would tell anybody to bye one ther worth the money kevin

Comments: Wavemaker and Koralia are a gteat combination and were a cinch to set up. Pumps are very quiet and were up and running in a few minutes. The night mode sensor was a little touchy, but once I found the right spot, it worked perfectly.

Comments: I am only a beginner, would like to get a wavemaker have a beta tank 750 ltr very interested.Juct cannot afford it at the moment.

Comments: Having had Koralia pumps for a while, I needed a wavemaker but didn't want to have to give up on the great performance of the Koralias I have, So, decided to take the plunge and get the Koralia 2's with the wavemaker. They work great together! There is no noice at all from the pumps as they spin down and up and the controls of the wavemaker are simple and easy to remember. I like the flexibility that the controls give you to set the speed and frequency to whatever you desire. If I had to come up with one con for this unit it would be the blue led lights on the front of the wavemaker. They're very bright and distracting so you'll need to have the unit in a cabinet or at least facing the wall so you don't have to watch them. But overall a great product for great pumps.

Comments: With the photo cell this thing puts a vortech to shame. It has the same power as the vortech but doesnt need to be lined up all time.
<br />
<br />A+

Comments: the best wavemaker i have ever used corls growing a lot better
