External Fish Filters: How do external fish filters work

external aquarium filter external filters

are at the high end of filtration – they draw the water out of the aquarium into an external box or canister, where the water is pushed (by a water pump) through a series of different filters, and then back into the tank.

Size External Filter: What size external filter do I need for my fish tank

A good rule of thumb is to select a filter with a flow rate at least six times the volume of the tank —so for a 30-gallon tank you want a flow rate of about 200 gph (gallons per hour).

External Filter: How often should I clean my external filter

Be sure to replace the

filter media

at least every three to four weeks and give the filter housing a quick rinse. If any algae or debris has accumulated in the intake tube, clean that as well.

Fish Tank: Is it OK to have 2 filters in a fish tank

Don’t Multiple Filters “Compete” on the Fish Tank? It is true that if you use more than one filter on your fish tank, neither of those filters will perform as efficiently as it would if it were the only filter on the aquarium This is expected, but is not a problem.

What are the 3 types of filtration?


The Aquarium uses three main types of filtration: mechanical, chemical, and biological Mechanical filtration is the removal or straining of solid particles from the water.

Internal Filter: Is internal filter is better

Internal filters are better for small to

medium sized tanks

with small to medium sized fish External filters may have higher running costs than other types of filter because when you change the media, you will have to buy more of it each time, but they will generally go for longer periods of time before clogging.

How many times per hour should I filter my aquarium?


We generally recommend that on average, you turn over your aquarium volume four times per hour This means that if you have a 30 gallon tank, you need a pump and filter with flow rates of around 120 gph.

Right Fish Tank Filter: How do I choose the right fish tank filter

Flow rate is measured in gallons per hour, or GPH, measured by the amount of water that will run through the filter in one hour. We recommend that the filter has a GPH at least 4-6 times the tank volume For example, a 20-gallon tank should have a filter with an 80-120 GPH.

Canister Filter: Do I need a canister filter

Canister filters provide superior mechanical, chemical, and biological filtration for larger aquariums or aquariums with a lot of fish The body or “canister” portion of the filter is significantly larger than most power filters – imagine how much media canister filters are able to hold!.

Fish Tank: How often should you change gravel in fish tank

If you have a healthy and well-balanced fish tank, you may be able to go for several months without cleaning the gravel. However, even with a highly efficient tank, it is a good idea to clean gravel at least once every two to three months.

Fish Tank Filter: Why does my fish tank filter get dirty so fast

If your tank is too small, the fish will be stressed and the tank will get dirty much faster Your tank should not be overly large, however, or the fish will be uncomfortable and it will be much more space to keep clean.

Tank Water: How often should fish tank water be changed

Change 10 to 15 percent of the water each week If your tank is heavily stocked, bump that up to 20 percent each week. A lightly stocked tank can get by for two weeks, but that should be the maximum length of time between water changes as you do not want to place any stress on your fish.
