It delivers advanced 3-stage filtration using mechanical, biological, and chemical media housed in magnetic, easily removable modules for hassle-free maintenance. Featuring an adjustable diffuser for optimal water flow and aeration, it also supports integration with the HeatUp heater to reduce in-tank equipment. Italian-made, German-engineered, UL certified, and backed by a 3-year warranty, it ensures reliable, discreet, and efficient aquarium water care. ## Description The Oase BioPlus is a corner-mounted internal filter that keeps your aquarium water healthy and clear without stealing the spotlight. It delivers multi-stage filtration through mechanical, biological, and chemical media, including 20 ppi filter foams and 30 ppi carbon filter foam, to keep water clear and your aquatic environment healthy. An integrated diffuser with adjustable flow promotes uniform surface movement, prevents the formation of biofilm, and provides additional aeration, giving you precise control over current to suit your livestock and planted scape. When it is time for maintenance, EasyClean magnetic catches let you remove individual filter modules quickly and without disturbing the pump, so upkeep can be done without disturbing your setup. The BioPlus is also designed to accept the Oase HeatUp heater, integrating heating directly into the filter to minimize in-tank equipment and shield inhabitants from direct contact with the heater. The BioPlus 50 is suitable for freshwater aquariums up to 15 gallons. Italian-made, German-engineered, UL certified, and backed by a 3-year warranty. Review: Great filter - Saw this at my newest aquarium store. Liked the way it sprays. Name speaks for itself. They use this in their tank for Mudskippers. I have 4 myself and will be building them a new enclosure. Review: Update on ease of cleaning 2023 - Read below to see my original experience which I now realize was more a result of incomplete instructions rather than insufficient design. I did not realize that the entire filter assembly is held to the motor unit by magnets and that if you grasp it by the slots on the side of just the filter housing it pops off easily and is thus easily disassembled and cleaned. I do not think this is clear in the instructions but it is in fact how it works. Thus I take back my negative comments and whole heartedly endorse this filter. PS: I substituted the larger foam filter with a filter bag of charcoal which seems to work better. Sorry about the confusion... This filter is a pain to clean! 20 gallon tank w/ three small gold fish. Expect to clean filter on water change, about every two weeks, but don't expect it to be easy. You must first pry the filter away from the glass with a tool (butter knife) otherwise the suction cups holding it in place pop off then good luck getting it apart to wash the filters. I am a strong man with woodcutter's hands and I had to curse up a storm to get the cover to release. Dirty water, filter crud and mess got all over the counter. It's just a poorly designed latch system that definitely cannot be operated the way it is shown in the elementary brochure. The filter has good flow options but don't try to clean it in polite company! ## Features - DISCREET CORNER INTERNAL FILTER – Provides effective 3-stage filtration using mechanical, biological, & chemical media, including 20 ppi filter foams and 30 ppi carbon filter foam, for improved water clarity. - ADD A HEATER - Easily integrate our HeatUp heater into the filter.

Filter foams are housed in individual modules, each easily removable for quick maintenance. - INTEGRATED DIFFUSER WITH ADJUSTABLE FLOW – Diffuser allows for uniform surface movement, prevents the formation of biofilm, and provides additional aeration. Adjust the flow based on your aquarium’s needs. - RELIABLE & BACKED BY WARRANTY – Ideal for freshwater aquariums up to 15 gallons (50L). Italian-made, German-engineered, UL certified, and includes a 3-year warranty. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07DFPQQ61 | | Best Sellers Rank | #93,950 in Pet Supplies ( See Top 100 in Pet Supplies ) #440 in Aquarium Filters | | Brand | OASE | | Brand Name | OASE | | Customer Reviews | 4.4 out of 5 stars 27 Reviews | | EU Spare Part Availability Duration | 1 Years | | Global Trade Identification Number | 00706759551526 | | Included Components | Aquarium Filter with suction cups, diffuser, fittings, and power cable | | Item Dimensions L x W x H | 4.7"L x 4.3"W x 4.7"H | | Item Type Name | Filter | | Item Weight | 1.3 Pounds | | Manufacturer | OASE | | Material | Plastic | | Material Type | Plastic | | Model Name | BioPlus | | Model Number | 55152 | | Other Special Features of the Product | Filtration media is individually housed in separate modules for simple cleaning and maintenance that can be removed while the filter bracket remains in place, Fresh water compatible, Made in Italy, backed by German engineering | | Part Number | 55152 | | Product Dimensions | 4.7"L x 4.3"W x 4.7"H | | Special Feature | Filtration media is individually housed in separate modules for simple cleaning and maintenance that can be removed while the filter bracket remains in place, Fresh water compatible, Made in Italy, backed by German engineering Special Feature Filtration media is individually housed in separate modules for simple cleaning and maintenance that can be removed while the filter bracket remains in place, Fresh water compatible, Made in Italy, backed by German engineering See more | | UPC | 706759551526 | | Warranty Description | 3 year limited + 1 year warranty extension with online registration | ## Product Details - **Brand:** OASE - **Color:** Black - **Item Weight:** 1.3 Pounds - **Material:** Plastic - **Product Dimensions:** 4.7"L x 4.3"W x 4.7"H - **Shape:** Rectangular - **Specific Uses For Product:** Indoor - **Style:** Bioplus 50 - **Tank Volume:** 15 Gallons ## Images ![BioPlus 50 Compact Internal Filter for Clean & Clear Aquarium Water – Easy Maintenance, Discreet Corner Mount, for Freshwater Tanks up to 15 Gallons - Image 1](https://m.media-amazon.com/images/I/81IVAyOlGVL.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: Will this product work well with a 55 gallon fish tank.** A: This filter is way too small for a 55G. I use mine on a 15G tank that is very lightly stocked. **Q: Made in the USA?** A: The OASE BioPlus filter is German engineered and made in Italy. We hope this helps! Best Regards, Your OASE Indoor Aquatic Specialist, Jennifer. **Q: 230 volt?** A: Hello. The Bioplus 200 has 120V/60HZ. We hope this helps! **Q: Can this be used in a 20 or 40 gallon turtle tank?** A: The Bioplus 100 is recommended for up to 30 gallon tanks by the manufacturer. Turtles being dirtier than fish i would want to make sure i had plenty of filtration so i would not use the Bioplus 100 on a 40 gallon tank but would move to the Bioplus 200 for that size tank. You also may want to add a heatup heater to the filter.

Name speaks for itself. They use this in their tank for Mudskippers.

When cleaning there is a good amount of bio product that escapes back into the water when the filter is pulled from the housing but, gets sucked back up soon enough with the replaced/cleaned filter. ## Frequently Bought Together - OASE Indoor Aquatics Bioplus 50 - OASE Indoor Aquatics HeatUp 50 Watt Aquarium Heater --- ## 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/95000261-bioplus-50-compact-internal-filter-for-clean-and-clear-aquarium](https://www.desertcart.gr/products/95000261-bioplus-50-compact-internal-filter-for-clean-and-clear-aquarium) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-06-28*
