its a hob
skimmer, dont have a sump really wish i did. problem with putting a pic on, my camera is crap.sorry. will have to get a new one. one problem i have is the return pipe from the chamber goes in to a bubble basket with foam in it but it does not sit very well so its not at the right water level and that causes alot of bubbles to over flow. think i will have to put up with the bubbles until i upgrade, which i will and get a drilled tank with sump.
