Frequently Asked Questions

Amoskeag-Fishways-FAQs

How powerful should my fish tank filter be?

Filters for aquarium filtration are categorized by their flow rate. In other words, their power output is demonstrated by their provided GPH (gallons per hour) measurement. A suitable filter for an aquarium will have a GPH rating of at least four times its tank’s capacity.

For instance, a person with a 100-litre aquarium (about 26 gallons) should choose a filter with 104 GPH or higher. Since you won’t find an exact 102 GPH filter, a 105 GPH or 110 GPH would be perfectly fine.

Can you have too powerful a filter on a fish tank?

Filters can be too powerful and cause severe problems for the fish inside your tank. For instance, they can give aquatic creatures trouble swimming through the strong current.

Therefore, buyers must avoid using filters designed for large tanks as small aquarium filter devices. Instead, you should stick with the recommendations in each filter’s product description. Or follow the rule that a filter’s GPH flow rate must equal four times your tank’s capacity.

Are canister filters better than power filters?

Both canister and power filters have situations where they’d be a better choice. For instance, a canister model offers more effective filtration, but it also comes at a higher price.

It’s why people usually only use canisters for larger tanks with a lot of fish. They are an excellent choice for working as a 55-gallon freshwater aquarium filter.

But a power filter aquarium device, also known as a hang-on-the-back filter, will be affordable while being a bit more convenient with its installation and setup. It makes them an ideal choice for a small tank or anyone new to being an aquarium enthusiast.

How long do fish tank power filters last?

A power filter can last a couple of years without needing a replacement. But it’ll require a thorough cleaning more frequently than other types. This issue stems from it being an internal fish tank filter, which picks up worse wear and tear. So buyers must clean the filter every week or two weeks to promote its longevity and performance.

What are the most trusted aquarium power filter brands?

You are probably well-aware that there are so many power filter brands available today. And, to help you ease the confusion of which one to get for your tank, the top-tier and most trusted brands are the following:

  • Aqua-Tech
  • Tetra
  • MarineLand
  • Aqueon
  • Marina

How to install and use?

Installation generally differs hinging on the brand and model you purchased. Hence, it is sensible to carefully read the manual for more specific and exhaustive installation directions.

Meanwhile, here are the general or basic instructions when setting up a power filter for your tank:

  • Once unboxed, inspect the filter carefully. Check if there are damages or defects.
  • If the device is in good condition, wash it off thoroughly. Keep in mind that this is particularly essential for any carbon filters since it maneuvers the carbon around, tidies any loose bits and guarantees efficient contact with the water after setting it up.
  • Set up the intake tube. Note that this must lie toward the underneath section of the tank. This should be roughly an inch or so above the gravel. Generally, you could consider cutting the tubing to enable it to lie at a suitable height.
