For years, I have had charcoal in my aquarium filters – whether information technology was a freshwater or a saltwater tank. I have been trying to abound alive plants in a 10-gallon freshwater tank lately and decided to take the charcoal out and so as not to impede the plants growth and to see what would happen.

Activated charcoal is not required in an aquarium filter. Charcoal in an aquarium filter can help to remove chlorine and chloramine also as other molecules constitute in tap h2o, so it is benign for some things. If y'all are medicating an aquarium, the charcoal should be taken out of the filter as it volition absorb the medication – thus minimizing its full potential to heal the sick fish.

There are pros and cons to using charcoal in an aquarium. Do you need to have charcoal in an aquarium filter to have a successful tank? No, you sure don't. In that location are times you might want to include it in the filter and and then other times when it'south okay not to accept whatsoever.

In this article, I will do my all-time to clear up why yous might want to use it and what not. I will also use activated carbon and charcoal interchangeably as they are the same thing. Let'south get started.

What Does Charcoal Do in an Aquarium Filter?

As mentioned above briefly, activated charcoal does have some benefits. Only putting it in the filter though without agreement this is potentially a waste of time and money and might have negative effects on your fish tank.

First, what is charcoal/activated carbon? It is made from carbon rich materials that are heated to very hot temperatures. Information technology is later formed equally you lot see it when purchased. In the aquarium world, activated carbon can be used in either pellet or powder form.

Using charcoal is an excellent fashion of removing undesired molecules and metals in tap water that might be fine for you to swallow however, letting a fish live in it might be detrimental to their wellness.

These elements include (but aren't limited to) are chlorine, chloramine, heavy metals, and organic materials.

Activated charcoal tin be used to both clean-upward a stinky fish tank and make the water clearer than if you weren't using it.

On the other manus, using charcoal doesn't help to rid the aquarium water of other elements such equally phosphates, ammonia, nitrite and nitrate. If charcoal did remove these things, then at that place'd be no existent reason not to utilise it in the filter.

Tin You Use Activated Carbon in a Planted Tank?

Technically, you tin go ahead and put charcoal in your planted tank. I say technically because yes, you tin can and with some live plants, they might exist fine, but others might non be.

The problem, yet, is that activated carbon will clear so much out of the h2o that it'due south really stripping some of the skilful bacteria that plants need to survive. This is what you want when using charcoal although, if you're growing plants, then yous should reconsider using it.

Plants thrive on CO2 and nitrate in the water. They absorb the CO2 and nitrate, which improves the quality of the h2o and makes the environs safe for fish.

It'due south my understanding that charcoal will scrub the h2o and remove some of the CO2. If this is true, then the charcoal is actually removing some of what plants need to live. Therefore, using charcoal in a tank with plants isn't a adept thought.

In add-on, if you are using any type of aquarium alive constitute fertilizer, you'll exist wasting your money if you leave the charcoal in the filter. Charcoal volition absorb the institute's food, rendering it useless in the tank.

Charcoal does the same with medications so it should only make sense that it will absorb plant fertilizers.

How Often Should I Modify the Charcoal in My Fish Tank?

Charcoal can be left in the aquarium filter for 6 to 8 weeks. The packaging will tell you to modify it out every 30 days or and then but that's just a company trying to sell a production.

If you take put charcoal in the filter for a specific task such as cleaning medication out of the water, then irresolute it every, one to two weeks is fine for a month or so.

If you cull to have charcoal in your filtration all the time, so get with the half dozen to 8-week fourth dimension frame. I accept left mine in for a few months at a time with no issues arising.

Tin can Activated Carbon Kill Fish?

I have never heard of anyone having an issue with using too much carbon. This doesn't mean you lot should become ahead and jam the filter up with it! Always use the recommended amounts in your tank, even if y'all probably can't put besides much carbon in a fish tank.

Usually filters take a spot to identify these types of mediums so you can only put and so much in, regardless.

Technically, if you use a powdered carbon in place of pellets, you can pack more of information technology in the same amount of space. All this volition practice though, is jam up the water flow in your filter, which in turn could cause health problems for your fish.

Then, but put in the recommended amount for your filter size. My rule-of-thumb is the corporeality of charcoal should non exceed the size of the filter sponge. They both should be about the same size.

Does Activated Carbon Remove Ammonia?

Unfortunately, activated carbon doesn't remove ammonia. If you are having problems with besides much ammonia in your tank, endeavour these things to troubleshoot the issue.

Let your fish tank's water bicycle properly when information technology is outset set upward. This is called the Nitrogen Wheel and until your water parameters are in check, you lot should not be calculation fish to the tank.
You can buy filter medium that is fabricated solely for the purpose of stripping ammonia from the h2o. Here'southward an Ammonia remover production you can purchase on Amazon.
Make certain you are treating all tap water y'all put in your tanks. You tin can let tap water sit out for 24 hours and that will clear-upwards most of the chemicals in the water, all the same nothing works better than using a water conditioner.
I would recommend frequent water changes. If you are non changing the water at least every two weeks, then you better start doing so. I do water changes once a week on my freshwater tanks.
Lastly, don't overfeed your fish. I would estimate that more than 75% of all fish owners overfeed. Your fish tin can survive on a lot less than yous're probably giving them and feeding them only what they need is healthier for them in the long run. Overfeeding affects not simply ammonia levels merely besides increased dangerous nitrate, which will kill fish if the levels are left unchecked in your tank.

Determination

Using activated carbon in a fish tank when its only getting started is a proficient thought. The charcoal helps to articulate out harmful elements of the water, making it safe for you to add fish once the tank has cycled.

That said, if your tank has been up and running for 6 months or more successfully with fish and no credible issues with the h2o, I would try taking the charcoal out. Monitor how the fish are doing and replace if they seem to start acting differently.

I expect everything should be fine. You can e'er add together charcoal quickly if afterwards a while you feel you need to and the charcoal volition become to work immediately.

So, the final verdict is in and no you practice non need to have charcoal in your aquarium filter, unless you are specifically trying to clean out the water. If you have recently used medication or are finding the water isn't every bit articulate as you lot call up information technology should be, then try charcoal.

Hopefully, this article has been of assist to you. Cheers for reading and good luck with your aquarium hobby.
