Aquarium LED lighting is a hot topic right now. A lot of people are using led lighting simply to enhance the color of the tank for a better visual display. However, others are starting to understand that high quality aquarium lighting has an effect on the growth of plants, the health of fish, and the strength of corals. This is really important. Choosing lighting for your own reasons is a personal choice, there’s no ideal option for your to use.

When you’re thinking about choosing the best led aquarium light. There are a lot of factors to consider when choosing the best led aquarium light for plants, let’s take a look at some of those important deciding factors that might affect your decision.


What advantages of aquarium led lighting are there?

One factor that many overlook about this type of lighting is the fact that the led aquarium lighting is more cheaper to run that regular fluorescent tubing. Using less power of a 24 hour basis is better for the planet and for your wallet.

The other, more traditional aquarium lighting can become really expensive to run throughout the day, because of the amount of power that these lighting is using. This is why it’s recommended that you consider buying the best led aquarium lighting and not the tradional lighting that you still get in many fish tanks.

Using a top LED makes your tank plants grow to their best and that makes your filter cleaner too!

Good preparation

When selecting the ideal lighting for your aquarium, you need to known the main reasons for what you want from it. The best fish tank lighting will fit all your needs.

Are you using it to grow live rock, or to simulate more natural light for your fish? Perhaps you are using the led to help grow coral. Do research into the best led lights for aquariums and you’ll be able to select the best one for your needs.

Not all led lights are created equal so don’t spend money until your know what your needs are. The size of your aquarium also presents a practical issue too. High concentrations of coral might require extra lights, or even coral might require just one large light across the whole tank.

LED color 

Led lighting now has multiple options for colors. They even simulate natural light cycles. A lot of people prefer colored lights, but some people like just have a white spectrum light.

Personally, I prefer a blue LED light, as this gives the tank a natural ocean colour. But if you have a tropical tank, maybe a green of white from bring out the best in that environment.

I advise that you go with the best led aquarium lighting that can recreate the most natural effect, both for plants fish and coral.

How many lights should you have

The best led aquarium lights are ones that cover the whole of the aquarium. But now you can have spot light leds that concentrate alight in one area of the tank. Some choices are more common than others. It really is a choice of personal taste.  For me the best results is with layered LED lights, one at the back and one at the front. This way you can control depth.

Of course, if you have a smaller tank then you can do fine with just one light, a bigger tank is going to need more or bigger lights to have the same effect on the aquarium or tank aura.

Avoid cheap branded LED lights

Good LED lights are expensive. Cheap LED lights are all around and are being mass produced for the aquarium market, don’t always buy the cheapest, you’re likely to have a short lifespan and lights that aren’t waterproof or designed for fish tanks. Think of the lights as an investment, after all they save you money in the long run. If you have to keep replacing your lights every year then there is no point in having LED lights in the first place.

The best led aquarium lights for your aquarium is a debate that isn’t settled. There’s no correct answer and each specialist will have his or her own opinion. Keep in mind the above as you make your decision for the best led aquarium light.

How often should you clean a cannister filter?

Even when you have a top cannister filter, it will require regular cleaning. These are essential actions to ensuring longevity of the filter and the fish. You need to know how and when to clean the filter though!

Cleaning your canister filter:

This youtube tutorial is a great start for your cleaning:

Filters should be cleaned out about every 2 – 3 months and a water change should be done every month. I prefer to clean them both out at the same time as it makes it a lot easier. Some people don’t clean the whole filter out at once though.

Important note on cleaning and the nitrogen cycle:

The filter works because of something called the nitrogen cycle, and that uses good bacteria inside the filter to turn waste products into nitrogen, release as gas through the surface of the water. So when you clean your filter out, you must make sure that you use treated water and not water from the tap!

The mechanical canister filter cleaning

You should focus on cleaning only the sponge pad or the fine filter pads. We call that the mechanical filtration. Remember again to only use the water from the tank or treated water to clean it. Most canister filters follow the same format of a 3 stage filtration process like so:


These mechanical filters and simply crude filters designed to pick out particles of dirt from the water, they can harvest a lot of bacteria, but that gets washed away when you clean them. That’s why the biological filters are so important. These very rarely need replacing because they are just a sponge basically.

Also note the biological filtration methods. This keeps good bacteria in the filter to clean and aid the nitrogen cycle.

Chemical cleaners

Chemical filters are filters like carbon filters. They are not intended to clean out bits of dirt from the tank, but improve odor of water color and stuff like that. It cleans a lot better than mechanical filters in this respect. You should change this type on a regular basis to keep fish happy.

A dirty carbon filter can leach out chemicals back out into the tank. 

The best way to know when to replace this filter is when the water begins to get a little cloud or a brown color. This means the carbon filter isn’t working anymore and you will need to replace it quickly. It is better to remove it than to wait until you have a new one as leaving it in the filter will mean that the dirt goes back into the water again and it could look worse than before the carbon filter was put in.
