Strong magnetic suction cup keeps the pump anchored to the wall. Head is adjustable to moderate and angle flow. It's easy to take apart and clean.The grates are small enough that they'll keep most fish out of the pump - avoiding the 'insta chum' affect. However, if you're breeding fish or have small aquatic life in your tank, you might want to add an additional layer of security and zip tie some plastic mesh around the grates - just in case. ### ⭐ Good product but this model is severely under powered!! *by on Reviewed in the United States September 29, 2018* Under powered power head not recommended for large tanks - also for some reason the hydros spread the flow out strangely and weaker than other power heads as presented in research videos online ... ## Frequently Bought Together - Hydor Koralia Evolution Circulation & Wave Pump , 550-600 GPH - 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.co.uk/products/8995770-hydor-koralia-evolution-550-aquarium-circulation-pump-550-gph](https://www.desertcart.co.uk/products/8995770-hydor-koralia-evolution-550-aquarium-circulation-pump-550-gph) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-01*
