Review: Excellent Design & Functionality. One of the Best Skimmers!! - This is actually one of the best surface skimmers I've owned and to be fair to other manufactures has a lot to do with design improvements over the years. Some others I've used in small tanks are: Eheim Skim350 (excellent skimmer but not for small fish unless install custom netting over the inlet); AquaNeat (budget price, decent but not best); ADA Vuppa II (quality built, pricey, skims well, motor mechanism prone to failure). What I like about the Oase 350: excellent skimming, inlet/outlet designs, pricing, functionality.
Review: It does work, but you need to work too. - It is not something you plug in and solved everything. You need to 1. Adjust the placement with the water level and when it is right, you will see the oily film running toward it. 2. Clean the filter regularly to continue working. 3. It can also be used to remove the duck weeds and surface trash. 4. For a 75 gallon, only one side will be able to cover, so you need to move to another side to clean the other side. It will not work for lazy people.

## Features

- QUICKLY CLEARS SURFACE DEBRIS – Removes biofilm, floating plant matter, and dust from the water’s surface to improve water clarity and support healthy oxygen exchange. Designed for use in both freshwater and marine aquariums.
- IMPROVES WATER CIRCULATION – In addition to surface skimming, the built-in bottom outlet creates gentle flow in low-circulation zones where debris tends to collect. This helps reduce dead spots and supports overall tank health.
- ADJUSTABLE FLOW & FLOATING RING – Customize skimming performance with an individually adjustable flow rate. The floating ring automatically adapts to changes in water level, maintaining consistent surface cleaning even when the unit isn’t perfectly level.
- SAFE FOR SHRIMP & SMALL FISH – A removable collection basket with fine intake slots protects delicate livestock while capturing the smallest particles that nets can’t remove. Ideal for planted tanks and aquascapes with shrimp or nano fish.
- RELIABLE QUALITY & BACKED BY WARRANTY – For aquariums up to 92 gallons (350 L). Italian-made, German-engineered, UL-certified, energy-efficient, and backed by a 3-year warranty.

### ⭐⭐⭐⭐ Great product overall but buy your own sponge to replace the one it came with
*by C***N on September 30, 2025*

Great skimmer. Perfect size for 20 gallon high but needs to be at lowest power if you also have a wake maker. The little thing can create a CRAP ton of micro bubbles at full power. The only complaint I have is that the sponge filter has too large of pores for my needs of filtering out silt. While it still filtered out some silt, I have purchased a sheet of aquarium sponge to custom cut to the size. Honestly, if you spend a couple bucks on a better quality sponge, this skimmer is worth the price! It is very small but powerful and doesn't any noise if installed correctly. The skimmer is the only filtration I have in my tank and it is working great!
