Filter for Small Fish Tank ReviewsWhen you get yourself a small fish tank, one thing you got to do is also get an effective filter for the tank.

There are many myths related to water filtration in the fish tank and giving them a look could help you better understand why you need one today.

Salt keeps your fish healthy

This is one thing that is entirely strange. Fresh water has to stay fresh, so adding salt to it totally doesn’t make any sense at all.

The myth is probably caused by the fact that some diseases may be treated by raising the salinity of the water. However, it’s also false for the fresh water fish.

Air pump is fundamental

Some installed filters and noted that maybe adding an air pump is going to improve the filtration altogether. Most fish tanks don’t have any aeration and it’s a misconception to believe aren’t going to have enough oxygen if no air pump is installed.

Any fish tank needs carbon

Not only carbon isn’t essential in aquarium filtration, but there are also situations when carbon could actually lead to serious problems.

You should always remove carbon from the tank before adding medication or liquid plant foods in the tank. Carbon from a filter should also be changed from time to time.

All fish tank need algae eaters

One may think that there is a miracle for keeping the tank clean all the time. Adding some “scavenger” fish is a solution, according to some, but, truth be told, it has nothing to do with the real life.

Constant cleaning and a good filter is going to get you there instead.

A small tank is great for beginners

As a matter of fact, small fish tanks are high maintenance and prone to various problems. They are, in fact, a better choice for the more experienced aquarium keepers that know a lot about taking care of a tank.

If you’re a beginner, a 15-30 gallons’ tank is always the better choice.

A high Ammonia level to cycle is also important

Ammonia is displacing dissolved oxygen from the water, so the higher its level, the more difficult for the biological filter to cycle.

What you should be doing instead is to have small water changes as your tank is cycling.

Conclusion

There are many myths related to water filtration for your fish tank and, no matter what you hear, having a good filter and cleaning it from time to time is the most important thing to do for keeping your fish happy and healthy.
