i just bought the jebo 180 skimmer, I KNOW that these skimmmers are crap but i needed something to hold me over for a couple months till i can get the skimmer i want. what i want to know is if someone had some sort of sucess with this thing and if they did how did they do it. did you change the pump, did you use it hang on back style, did you do the in sump set up? i have haad it for about a week and has pulled out absolutley nothing!! its like the bubbles do wanna reach the top of the colleection tub to fall into the cup. right now i changed it from hob to in suump to see if it works better. so if anyone has used these and gotten some sort of use let me know, like i said, all i need it for is like 2 or 3 months.
