You HAVE to buy the Hydor Wave Controler (and really need at least 2 pumps on either side of your tank), to create a wave effect. I just bought a 425 and it has ok flow across a 20 long tank ( but no waves). You can attach it to a regular timer if you just want to run it at certain times. That was no good for me so I ordered another higher rated pump AND the wave controller. I'll see how that works when I get it. I wanted a "shimmer" effect from my moonlights. To get this I needed to put it at the top of the tank to push the surface enough. Now I have a slight shimmer. **Q: I have a 25-30 gallon tank, which option is best?** A: I have a darter tank that has about 25 gallons of water in it. I just replaced a 500 GPH water pump with the 850 GPH circulation pump. The water pump really blasted quite a jet of water across my tank. The Hydor is much gentler, with a broader spread, but still seems to make for a nice stream simulation. While the 500 GPH was about the maximum my tank could handle, the 850 GPH circulation pump is just adequate for a stream simulation. My main reason for switching was the circulation pump only uses about 5 watts of electricity, while a 500 GPH water pump uses about 35. I'm hoping to see my water temperature drop. If you are simulating a swamp, however, I would not recommend this product at all. **Q: What voltage does it run on: 110v or 240v? Thanks** A: 110v in my house here in the US! **Q: What size and how many of these power heads should I get for 90 gallon reef** A: I had two 1400 on my 90 and it's too much, stirs the sand up. ## Customer Reviews ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Five Stars *by J***F on Reviewed in the United Kingdom on 20 June 2015* Excellent item but returned to seller for refund as not suitable for size for my aquarium ### ⭐ 1.0 out of 5 stars Great magnet *by C***F on Reviewed in the United Kingdom on 26 March 2021* 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 ### ⭐⭐⭐⭐⭐ So far, so good with this SILENT wave maker! *by K***L on Reviewed in the United States on 24 November 2024* 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! ## Frequently Bought Together - Hydor Koralia Evolution Circulation & Wave Pump , 750-850 GPH, 115 Volts, Black - PAIZOO Fish Tank Digital Thermometer Accurate LED Display to ±0.9°F Tank Thermometer Aquarium Temperature Measurement Suitable for Fish, Axolotl, Turtle or Aquatic - CaribSea Arag-Alive 20 lb Fiji Pink Sand --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/423428437-koralia-evolution-circulation-and-wave-pump-750-850-gph-115](https://www.desertcart.jp/products/423428437-koralia-evolution-circulation-and-wave-pump-750-850-gph-115) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-05-23*
