In this article, we will be taking a look at how to prevent fish from getting stuck to filter to help protect the fish in your aquarium. Although rare, we have noticed a number of aquarium enthusiasts reaching out for assistance on protecting their smaller fish from getting sucked into their aquarium filters.
We have researched the various method out there and decided to publish this article to help any of our readers who find their self in this same situation. Although we will be covering a number of different methods, you should be able to protect your fish by only implementing one or two of them rather than all of them.
Use A Foam Pre-Filter
They are quick and easy to use and have a minimal effect on your water flow as the holes in the foam still allows a large amount of water to freely flow through them and get to your filter or pump. As they have been specifically designed for this purpose and use in an aquarium, there is no possible contaminants on them or impurities that may cause problems with your tank. When aquarium enthusiasts approach us looking at how to keep fish out of a filter we always recommend these.
Hide Your Intake With Decorations
Although some decorations may still allow your fish to get close to your filters intake you can use additional decorations or plants to make it harder and help keep your fish safe. The more creative you get the better, we have seen some excellent ideas where the intake of the filter has been extended with additional tubing that is hidden under substrate to get the intake to a specific decoration.
Again, as aquarium decorations are specifically designed to be used in a tank with fish, plants, and other animals there is no risk of contamination when using this method.
Use Tights To Protect Your Fish From The Filter
The main problem with using women’s tights is that some of them have chemical coatings on them that can potentially cause problems with your water. Even if you were them multiple times before adding them to your tank, there is still a small risk so we always recommend a high-quality foam prefilter than only costs a few dollars more that is totally safe.
Make Sure That Your Fish Are Healthy
Although this one may seem like common sense, it is often overlooked by many aquarium enthusiasts. Even very small fish should not have any problems out swimming a correctly set filter if they are healthy. When we mention healthy many people think of obvious problems in the fish but things such as the nitrate levels in your water can have an effect on some fish so remember to take things like this into account too.
Check The Input Flow On Your Filter Is Set Correctly
The final mistake that we see people make, especially new aquarium enthusiasts make is that they will set their input flow too high on their filter. This will increase the suction power and end up either sucking fish in or getting fish stuck on the filter.
Double check the instructions that came with your filter or check out the manufactueres website as it will explain the recomended settings for various sized fishes. It is usually a quick and easy but high effective method that you can take advantage of to help keep your pet fish safe.
