Would highly reccommend ### ⭐⭐⭐⭐⭐ Looks great but pump doesn't work *by J***Y on 3 November 2025* The refugium is amazing it's the perfect size for my 40 gallon tank. I had problems with the motor at first but they said they would send me a new pump. I hate that I just now found out about this. I definitely have been missing out on a great thing for my tank. ### ⭐⭐⭐⭐⭐ Worth... The... Money! *by D***Y on 15 April 2024* This thing is totally worth the money, and very very quiet, I cant hear it over my fluval 407 on the other side of this 75 gallon tank. Be warned! The corner where the motor intake rests is vulnerable to break, BUT NOT IN THE WAY YOU THINK! The corner of mine unfortunately broke off but I glued it right back on! Do not force the mounts in any way, I made the error of making sure it was resting on the rim securely by adding some pressure downward and it broke, just nestle it into place. I have a rimmed tank, don't bother cutting the plastic rim to try to get it to rest flush, you run the risk of what I tried to do, the screws will actually clamp onto the rim and the pump is more than powerful enough to pull water even an additional half inch up, so no cutting is required. Really clean look and easy to customize as far as lights, it's built with two support braces to keep the center from bowing out and seconds as a light rest for any light bars you might get, what I have is temporary until I get one myself! Fits really flush against the tank despite the rim so I'm impressed there! I have gar so still water is needed, the sponge/flow breaker for the outlet is really nice, keeps the top water nice and still, or just remove the sponge if you want it to stir up the surface! Really awesome design in all honesty, they thought of everything you might want out of this thing, just don't force the mounts! Will be getting another for my 55 as well, very satisfied and worth the money! ## Frequently Bought Together - AquaReady HOB-R Hang On Back Refugium - Natural Macro Algae Filtration for Freshwater and Saltwater Aquariums, Increase Beneficial Marine Tank Bacteria and Micro-Fauna - Innovative Marine ChaetoMax Refugium LED Light (9 Watt) --- ## 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.es/products/622514415-hob-r-hang-on-back-refugium-natural-macro-algae-filtration](https://www.desertcart.es/products/622514415-hob-r-hang-on-back-refugium-natural-macro-algae-filtration) --- *Product available on Desertcart Spain* *Store origin: ES* *Last updated: 2026-05-28*
