Aquarium filter

Designed to fit power nozzle pumps upto 100-150L pending the size. I'm using a 100L/H Aquaone but anything will do.

Per the image with numbered boxes:

1 & 2) Medium filter sponge
3) Carbon filter sponge
Below the pump goes biological media balls

Water must pass all 3 chambers in order to be pumped out. I used > PURE < CA glue to bond as thats fine, marine silicone will also work. There is a cap for the filter bottom and another cap to go in the front exit, this may need tweaking pending the pump you have.
