hagen aquaclear quick filter without the filter cartridge on all of my hagen powerheads . you can also put rain gutter guard plastic mesh in it for extra screening but it's not really needed . i run a seio m620 as is , so far so good but would not rec. doing so with bta's because of how small they or their clones can be when they divide .
