I was just at the LFS
yesterday and was thinking of Mike when I saw a WON 125g skimmer that claims it can be mounted on the back of a tank or in sump. Price was only $99. Anyone have any thoughts on these. I love the won heaters, but first time I have seem a Won skimmer.
If anyone has positive feedback for this unit it might be the way to go since you are thinking about a sump down the road.
