Well the "sponges" in my Two little fishies GFO reactors need ot be changed.
Now i know i can go on and get them for a couple bucks but does anyone have a alternative that they can purchase in a normal store? The material almost seems like it would be common.
Yeah I have seen that material at petco/petsmart even its pretty basic stuff... just might have to cut a fancy hole in it/ trim it to the size you need which shouldnt be that hard, even for you
if you weren't trying to get my a potters wrasse i'd strangle you.
