Chemiclean vs Red Slime Remover: Detailed Comparison

Comparison between Chemiclean and Red Slime Remover

Now it’s time for you to know the differences in detail. Here I have explained all of the differences in detail and their importance too. It’s time to make a start!


Price is a very important feature in order to buy anything.

The prices of Chemiclean depend on its amount. If you buy a Chemiclean for your 300-gallon aquarium water, then it can cost you around $17. The more you want, the more it will cost you.

Red Slime Remover is also a pricey product. If you want it buy a Red slime remover, perfect for your 300-gallon aquarium water. Then it can cost you up to $28. 


Red slime with remover is costlier than Chemiclean according to their use for the same quantity.

Killing Procedure

The killing procedure of both of them is effective but still, there are some differences between them. Let’s know them.

Chemiclean kills the red slime through oxidation. In this process, they limit the photosynthesis process. For this, the level of dissolved oxygen increases in the water. It also makes the aerobic bacteria stronger.

Because of low photosynthesis and their strong enemy, aerobic bacteria, the red slime eventually dies. It can take up to 48 hours for the best results.

And for best results, you can also keep an air stone in the aquarium before the procedure. There are no harmful things in the Chemiclean ingredients.

Red Slime Remover works through a unique process. The name of this process is antimicrobial activity. Red Slime Remover is actually nothing but an antibiotic.

It works in two steps. First, it blocks the nutrients from going to the bacteria. Because it helps in their vital processes and their living. Second, it prevents the growth or multiplication of those bacteria.

As a result, they can’t grow and because of fewer nutrients, they die too. It can also take up to 48 hours for the best results.


Both of the processes are effective but they adopt the opposite steps for killing them.

Water Change

After using Chemiclean and when the full treatment is complete, you should always change the aquarium water.

You should at least change 20% of the aquarium water. Chemiclean water change is a must step for everyone.

There are not any kind of instructions in the manual of the products to do any kind of water change after or before the procedure.


Water change is a must step for the Chemiclean, not for the Red Slime Remover.

Removal of Chemi-pure or Carbon Filtration

There are some machines in the aquarium. If you tend to follow any kind of treatment, then for some treatments you may need to remove or turn off them.

As Chemiclean works through oxidation, that’s why it’s very important to remove the carbon filtration and the chemi-pure.

You should do it before starting the treatment. You should keep them away from the aquarium for at least 24 hours.

Whereas, for red slime, you don’t need to remove carbon filtration or chemi pure to follow this treatment. There is no necessity for this part.


Removal of Carbon filtration or Chemi-pure is necessary for Chemiclean, not for Red Slime Remover.

Clarification of water

Chemiclean doesn’t only kill the red slime or cyanobacteria but also can clean the water. For this, the water becomes very crystal clear. It’s like a part of the regular maintenance of the aquarium.

As a result, you can get two benefits with a single one, killing red slime and clarification of water.

There is not any specific or clear information about the clarification of aquarium water by Red Slime Remover. So, it can be said that it can’t do this.


Chemiclean can do clarification of water but Red Slime Remover can’t.

Types of Killed Bacteria

Chemiclean only concentrates on killing red slime. They don’t clean the other bacteria. They even promote the growth of aerobic bacteria.

Red Slime Remover is an antibiotic. That’s why it kills all kinds of bacteria. It doesn’t care which kinds of bacteria they are.

They just target and kill them. There is no mention of this in the instructions.


Red Slime Remover kills all kinds of bacteria but Chemiclean only kills the harmful ones.

So, Which One Is Better?

Both of them can provide you with the best results.

But as you can see, if you buy a Red Slime Remover, you don’t need to remove or turn off any things or machines. As these are a great hassle before any treatment. And it also kills other harmful bacteria.

And if you buy Chemiclean, there are also some benefits of it. First of all, it is less expensive. It doesn’t kill the necessary bacteria. And it also helps you in the regular maintenance of water.

Hoping that you can choose according to the criteria you need. 

Red slime can also put some stains in the aquarium. So, to help you, here are some red slime stain removers for you. Hope this will be helpful for you.

Can Vibrant Kill Red Slime?
