Canister Filter

Come on below to read all the crucial features of the polar aurora canister filter.

Four Media Tray

For exclusive filtration, the Polar Aurora 4 stage Canister filter features 4 different media tray. These trays are capable of holding different media according to your choice.

It means you can get mechanical, chemical, and biological filtration at the same time by adding some media to the trays like bio-balls, ceramic rings, or activated carbon.

The 4 stage media tray ensures that the water goes through a lot of phases of filtration and your fish can get the clean water.

Adjustable Spray Bar

The adjustable spray bar is included so that you can adjust the water flow. This is a helpful feature when you want to adjust the output flow from the filter.

Sometimes you might just want to keep your tank noise-free or you’re getting your fish out of the tank, you’ll need to decrease the water flow rate. This feature will help a lot then.

9 Watt UV Sterilizer

The Polar Aurora 525 GPH external filter contains a 9 watt UV bulb to protect your tank from algae problems. It also prevents any kind of bacteria from growing up in your tank.

With this UV Sterilizer, your fish will be safe and out of any harm. Besides, the water will be as clean as possible. Your fish will like this very much.

The bulb will provide a bit of illumination too! This will help you to watch over your fish when the surround is dark.

The O-ring

This feature seems to be the simplest but trusts me, this feature made it one of the best canister filters because it gives you the assurance that your filter is not leaking. The O ring has located the opening of the Filter body.

When you attach the filter cap, the O ring helps it to stay tighten. You’ll get a leak-proof seal and you won’t have to worry about it for several months.

The Self Priming Pump

The filter also contains a self-priming pump. It means you don’t have to worry about manual siphoning. The filter itself can manage to do it perfectly. What you have to do is set up the filter correctly and that’s all.
