Review: I have a 60 gallon breeder, which is 4ft long, and am running co2. I have 2 Aquaclear 70's on the back, so don't have an outflow that a canister filter provides, and obviously not able to use an inline diffuser, so needed something to disperse the co2 throughout the water column. I first bought a power head that was just way too strong, so took that out within a few minutes and started searching again. Found this and it's perfect. Pushing the co2 to the other side of my tank, but not flattening or ripping out my plants in the flow. Using it with an atomizer, which is able to be tucked right beside the outflow on this. It's also very quiet, which makes it even better. Review: Lo uso en paralelo con un filtro de cascada para un acuario de 28 litros aproximadamente. Me ayuda mucho a mantener el flujo del co2 en todo el acuario ## Features - Three stage filtration of biological, mechanical, and chemical filtration are integrated in this compact design - Compact, yet powerful Filter operates quietly to circulate and filter your aquarium or paludarium's water - Adjustable flow control is built into the filter - All necessary fittings are included - Lightweight Filter with suction feet allows for simple and discreet attachment for horizontal or Vertical installation ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07H6TSJJ4 | | Best Sellers Rank | #86,126 in Pet Supplies ( See Top 100 in Pet Supplies ) #5,803 in Aquarium Accessories | | Brand Name | Oase | | Capacity | 25 Liters | | Customer Reviews | 4.0 4.0 out of 5 stars (57) | | Global Trade Identification Number | 00706759551410 | | Included Components | Aquarium Filter with suction cups, fittings, and power cable | | Installation Type | Freestanding | | Item Dimensions L x W x H | 5.1L x 5.1W x 5.1H centimeters | | Item Type Name | Filter | | Item Weight | 0.22 Kilograms | | Manufacturer | OASE | | Material Type | Activated Carbon | | Model Name | 55141 | | Model Number | 55141 | | Other Special Features of the Product | Activated Carbon Filter | | Part Number | 55141 | | Power Source | Corded Electric | | Purification Method | Activated Carbon | | Smart Home Compatibility | Not Smart Home Compatible | | UPC | 706759551410 | | Unit Count | 1 Count | ## Product Details - **Brand:** Oase - **Capacity:** 25 Liters - **Material:** Activated Carbon - **Product dimensions:** 5.1L x 5.1W x 5.1H centimeters - **Special features:** Activated Carbon Filter ## Images ![Oase Biocompact 25 - Image 1](https://m.media-amazon.com/images/I/51HcLG8wqqL.jpg) ## Available Options This product comes in different **Item Package Quantity** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by D***. on 9 March 2025* I have a 60 gallon breeder, which is 4ft long, and am running co2.

Me ayuda mucho a mantener el flujo del co2 en todo el acuario ### ⭐⭐⭐⭐⭐ Review *by E***A on 19 February 2025* I wanted a low flow filter for my fish tank which is a cubic 30x30x30 (cm). With this filter you can adjust the flow which is perfect for small fish and ideal for my betta fish. You can direct the flow in different directions with the added attachment and the filtration has been perfect for my tank, keeps it nice and clean in between water changes and when re-arranging my live plants. This filter is also very quiet which is perfect as the tank is situated in a bedroom. I would be careful when the handling of the filter, but it’s fine for me i just delicately wash the parts. Overall, impressed with this little filter. ## Frequently Bought Together - OASE Indoor Aquatics Biocompact 25,Black - Fluval 12694 Plant and Shrimp Stratum for Freshwater Fish Tanks, 8.8 lbs. – Aquarium Substrate for Strong Plant Growth, Supports Neutral to Slightly Acidic pH - API FRESHWATER MASTER TEST KIT 800-Test Freshwater Aquarium Water Master Test Kit, White, Single, Multi-colored --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/254365743-oase-biocompact-25](https://www.desertcart.gr/products/254365743-oase-biocompact-25) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-04-25*
