I used a Skilter 250 supreme on my first saltwater tank back in like 1991 LOL
even back then it wasnt very good. I dont recall it ever skimmed and the motor in it would always need slapped after turning on and off to get it running again. but hey I was 12 when I had that tank
I almost forgot that part. Slapping the hell out of that thing, thinking I was gonna break the glass on my tank.
