Although there are some things to consider in this case. If activated carbon is exposed to a lot of aquarium trash, it will quickly lose its potency.

In this case, the carbon is already added to the filter. Thus, it is important to keep your aquarium clean and free of debris. And that is on a regular basis.

Also, the activated carbon absorbs a variety of fish sickness treatments. Therefore, all carbon in the filter needs to be eliminated before administering medication to ill fish. In this case, it’s advised to remove the filter while treating your fish.

The stabilizer was created especially for aquariums. It comprises a synergistic mixture of facultative, aerobic, and anaerobic bacteria. It helps break down waste organics, ammonia, nitrite, and nitrate. The bacteria used by the stabilizer don’t fix sulfur and do not release harmful hydrogen sulfide.

This implies the importance of the stabilizer. Thus, if you want these benefits, go for the Fluval 407.

Price

So, if you can afford the extra 20 bucks, then Fluval 407 is the right choice.
