Review: Excellent value. Easy to use and maintain. - Excellent value for money. The filter has separate baskets, so you can customise your media, although it does come with different grade sponge filters, from a porous sponge, down to a water polishing wool. The unit is compact, easy to put together, and the size of it looks smart on the side of my 125L tank, although it is rated for a higher volume tank. It comes with a spray bar, which I haven't used, so can't really comment, and a jet. The jet is pushed onto a rotating ball fitting, which is useful for getting the desired surface agitation, and you can adjust the water direction and pressure a good amount as both the inlet and outlet are also adjustable. The filter picks up a good amount of debris from the tank, and the multiple baskets are easily removed, cleaned out and replaced. Remember to prime the filter before turning on initially, and after maintenance as if you get an airlock it is noisy and splutters. Even with it filled, I've experienced this a couple of times, which is my only complaint, but I am also not using the factory filter media which may play a part. Once it has blown it through the system, which usually takes a few hours, it is so quiet that the only way I know it's working is because the vallisneria is dancing along the back of the tank in the flow. The performance is excellent for the price, and it works just as well, if not better than products more than double the price of this. I like the fact that you get the convenience of an external filter, the size of an internal filter, in a compact package that hangs on the back of the tank, allowing you to use the full footprint and volume of the tank for aquascaping and planting. There's bad reviews, but for a medium sized open top tank on top of a reinforced ikea kallax unit, it fits the bill perfectly, as I don't have to have it in a separate cabinet, or elsewhere. For a similar installation as my one, I would definitely recommend this filter. Review: Well worth the money - Set up in 120l cold water tanks . Working well after 2 weeks .

I have mine on my 30cm cube 27 litre Beta tank. It hangs on the back perfectly, I have corse, medium, fine sponges in the bottom tay. Then Seachem Matrix, Seachem Purigen 100g and lastly Filter wool. I use the spray bar attachment facing forwards at 45 degrees towards the water surface and the inlet open fully to draw water from the tank and the outlet at minimum to reduce the flow. My Betta makes use of the whole water column with ease. The water stays crystal clear and the parameters are all stable. I haven't suffered any spikes or crashes. **Q: What's the wattage please?** A: This pump is 6W. I bought one for my Axolotl tank and was so impressed I bought one for each of my other 3 tanks. **Q: How wide is this filter.** A: 200 mil / 8 inches ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent value.

Working well after 2 weeks . Easy to set up and clean out . Doesn’t make a lot of noise , the tank is in my bedroom . ### ⭐⭐⭐⭐ Surprisingly Decent, if a bit awkward to maintain. *by K***E on 28 January 2022* I've been running this filter for 3 months now on a 35ltr Betta Tank. I figured, hey, it's cheap enough, not the end of the world if it's rubbish. And colour me pleasantly surprised, it's good! It was initially quite noisy, I gave it some time, rocked it about to loosen trapped air, but it was definitely a mechanical noise. I opened the entire thing up, unscrewing the lid and everything. Greased the impeller and all, but still noisy. Figured my gamble hadn't paid off, unplugged it, plugged it back in for some reason and viola, quiet! No idea how and why that worked, but it's been quietly working away ever since. I was a bit scared to mess with it in case it became noisy again, but eventually I had to give the filter media a rinse. The noise came back on reassembly, but again, unplug, replug and all was quiet again. Make of that what you will. I have yet to have any leaking issues personally. It is admittedly an awkward filter to maintain if you don't have much room around whichever side of the tank you put it on. It's quite heavy due to it having such a large capacity canister, and the design requires you to lift the whole thing away from the tank to unclip the canister for maintenance. Definitely would place it somewhere easy reach and lift if you have weak wrists, arthritis etc. And it can be fiddly/frustrating getting the layers of baskets to stay clipped together when removing/replacing in order to maintain the correct water flow through the canister. I also don't believe the flow adjuster valves are entirely airtight, as it can be a bit of balancing act between the in and out flow valves to get it so it doesn't suck a tiny stream of air in through them. However, outside of the mentioned issues, when it's all set up and doing it's job, it's a great filter for a very reasonable price. It's very adjustable, feels well made, has lots and lots of room for stuffing with filter media and happily chugs along doing it's job! :) ## Frequently Bought Together - allpondsolutions HOB-500 Aquarium External Fish Tank Water Filter for Coldwater, Tropical or Marine Aquariums, for Tanks Up to 250 Litres – Includes Filter Foams, hose and Spray Bar - Full Kit. - AQUARIUM BIO FILTER MEDIA CERAMIC MINI BALLS FISH TANK REMOVE NH4, NO2, NO3 (1kg) - Pond Foam Filter Media Pack (Set of 3) 17" x 11" Coarse, Medium and Fine. --- ## 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.sg/products/102459792-allpondsolutions-hob-500-aquarium-external-fish-tank-water-filter-coldwater](https://www.desertcart.sg/products/102459792-allpondsolutions-hob-500-aquarium-external-fish-tank-water-filter-coldwater) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-09-21*
