This my large format fry filter. I use this on 24 inch fry bowls. Makes changing water on a couple thousand fry easy. Works much quicker than an #airstonefryfilter but works on a similar principle of having large surface area. It’s made of a prefilter core of a Pentek pd 5-20 particle filter, fits right into 1” pvc adapted to tubing. The filter cot is covered with a 1/32” aquaculture grade polyester mesh sewn with 62 bonded polyester racing sail thread. #aquaculture #goldfishbreeder #goldfishgarageprotip #goldfishunion
