In the two videos shown below the king of DIY shows you how to create a DIY aquarium filter out of a large drum and a few other items from his local Walmart. I’ve always wanted to create a fish filter like this. I just never knew where to start or how to do it properly. You might learn some things from these videos on how to create a DIY aquarium filter. If you have created a custom filter in the past before let me know in the comments below.
