[Hustler]

Well here they are...
I dont know how long it taked for a skimmer like this to "break in" but it hasnt yet.
Also i dont know if I have enough to even make any waste in my tank?
If i do.... and it did.... Then Ive got to cut the plumbing again and buy 2 big bugger sub pumps
Its getting about 2000gph now...
