heard that prizm is suppose to be good, but noisy;unless you request newer impeller
we use the seaclone for the 135 & works fine & is pretty quiet;however, make sure you receive one w/ the shorter inner tube; we got ours from petwarehouse.com for about $70 or so S&H at the time
well i guess you get what you pay for
if you are strapped for cash maybe you should
save up till you can get a better skimmer i will be worth waiting for.been there it dosen't work.
Prizm. I've had mine running about a year(replacing my visi-jet <img src="graemlins//bah.gif" border="0" alt="[bah]" /> ) HUGE difference in proformance! The crap it takes out is unbeleivable. If you have a 55g or smaller i would suggest getting one of these. Best bang for the buck. Not that noisy (just thought i'd chime in on the noise issue)
