I have a WB Frag 105.4 I am currently running a BM curve 5 elite skimmer. when it works it works but its not consistent. The recommended water height in the sump is much higher than what I have going on. I bought it because of the small foot print, recommended water height is 9.5'' to 11''. The water level height in my sump is 8'' exactly and looking for something with a small foot print. Any recommendations is appreciated.
