Many other cheaper filters I’ve tried are generally rubbish but this one was a good find so I’ll give myself a pat on the back for that. I’m lazy so don’t clean it as often as I should but even so it doesn’t stutter on keeping the tank nice and clear and runs 100%. I did find the nozzle with the holes that give the waterfall effect is easily clogged with food debris and can be difficult to clean. I’ve had no issue with the straight nozzle however. Cable is a good length and the power in the water flow is great. It’s easy to put together and generally easy to clean as well as great value for money. Highly recommend. ### ⭐⭐⭐⭐⭐ Great filter for a small tank *by on Reviewed in the United Kingdom 10 April 2026* Fantastic filter, I needed a new one as the one that came with the tank I bought the filter was extremely noisy so I ordered this one. It's fantastic, quiet, easy to install and offers good filtration. ### ⭐⭐⭐⭐ Good affordable option *by on Reviewed in the United Kingdom 11 August 2025* Filter works well in itself, a little bit louder than I would have liked when it’s not in the water. Clarity of water is ‘ok’. Size is good, did have to give it a clean sooner than I would have liked. ## Frequently Bought Together - NICREW Fish Tank Filter, Internal Aquarium Filter for Small Tank, Coldwater or Tropical Aquariums, Up to 20L Black - AQUARIAN TAP WATER SAFE, Aquarium Water Conditioner, 118 ml Bottle,White - NICREW Replace Cartridge for Fish Tank Filter 150L/H & 200L/H, Aquarium Filter Foam and Active Carbon --- ## 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.gr/products/388858322-fish-tank-filter-internal-aquarium-filter-for-small-tank-coldwater](https://www.desertcart.gr/products/388858322-fish-tank-filter-internal-aquarium-filter-for-small-tank-coldwater) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-07-07*
