Even better is the fact that it should not negatively impact the water chemistry of your fish tank.

It should also be 100% totally safe for your fish, which is quite impressive seeing as it should be able to solve this problem within about 48 hours. What does however need to be said is that this treatment may be toxic to invertebrates, so any shrimp, snails, corals, and live rocks need to be removed from the water. Furthermore, this treatment is not safe to use in water that contains loaches.

Ich Treatment for Aquariums Buyers Guide: What to Look Out For

Before you go out and buy any old ich treatment for your aquarium fish, there are a few important considerations to pay attention to.

Type of Fish

When choosing any such treatment for an aquarium, always keep the type of fish in mind. Although most of the treatments that we’ve talked about today are fine for all fish, there are some that are not.

For instance, some treatments might not be fine for scaleless fish, and others might not be okay for invertebrates. Always make sure that the product in question is ideal for the fish that you have.

Type of Water

You then also need to consider the type of water that you have. Just like these treatments are not suitable for all types of fish, so are they not suitable for all types of water. 

Yes, there are some that are suitable for both freshwater and saltwater environments, but this is not always the case. Always make sure that the treatment within question is ideal for the type of aquarium that you have.

Amount Needed

You then need to take into account the amount of the product that you will need for your aquarium, which in other words means that you need to compare the size of your aquarium to the directions as included on the product in question. 

Always make sure that you purchase enough to treat your whole tank, and then some. If you don’t purchase enough, you might not be able to totally get rid of the issue, in which case it might come back stronger than ever.

Treatment Time

Different products may require different amounts of time to fully treat an aquarium of ich. Therefore, always pay attention to how long it says it takes to work. Some of the products we’ve talked about today take as little as 48 hours.

Cost

Finally, you should also consider the cost of the product in question. Although we certainly don’t recommend going with the cheapest products, if there are two products that both do the same thing, you don’t need to always buy the more expensive one. The most important thing here is for you to pay attention to the ingredients.
