The listing, make your own fish filters, save big $$ has ended.
I learned how to make my own own fish filters, (works for turtles to) it's simple and easy, I found everything I needed to make them at walmart (works best if you have old fish frames but I can tell you what to use if you don't) it costed me about $14 total and I can make a lot! I mean a lot!! and I can make different sizes for all my tanks, ( I have 2- 10 gallon tanks and one 30 gallon tank with 2 filters on it) so you know how many filters I go threw!!!! I will message threw listia only!
