FilterAir60 Breeder Sponge upgrade

bought an Aqua One sponger filter. it made huge bubbles at the very top of the tank and my poor shrimp were very sad and hugging the filter because it just recirculates water from the top to the sponge. print the sponge holder drop an air stone in it. make sure the barb faces the right end. glue the ring in the top. plug it into the base. if your printer makes a sponge holder that isnt snug enough to sit in the weighted base, just flair the end of the print slightly with some pliers for a snug fit.
