do you need internal or external ? i just got a vertex in 180 and it looks like a monster and is built very well, the etts sump buddy 40 is nice as well and the 60 would be a monster with a small foot print
My preference is Internal but want the option of external due to possible space constraints and sump water level height issues. I want to get a recirculating skimmer. I do not think Vertex In 180 is a recirculating though.
Thanks.
