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. ## 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.pt/products/239080469-koralia-evolution-circulation-and-wave-pump-750-850-gph-115](https://www.desertcart.pt/products/239080469-koralia-evolution-circulation-and-wave-pump-750-850-gph-115) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-06-07*
