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.

No parts got lost. Everything fits together like clockwork. Review: Great filter - Saw this at my newest aquarium store. Liked the way it sprays. Name speaks for itself.

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.

I had to clean it out quite a few times and I had no problems with it nothing broke, cracked or chipped. No parts got lost. Everything fits together like clockwork. ### ⭐⭐⭐⭐⭐ Great filter *by F***D on May 30, 2026* 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. ### ⭐⭐⭐⭐ Nice water flow *by A***R on February 8, 2024* Great for water flow and agitating the surface of the water with the adjustable dial at the top. 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.hr/products/95000261-oase-bioplus-50-compact-internal-filter-for-clean-and-clear](https://www.desertcart.hr/products/95000261-oase-bioplus-50-compact-internal-filter-for-clean-and-clear) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-09-30*
