Not impressed with Koralias

[Blueflu1]

Hmm. I have 3 Koralias in my tank and all three have been bulletproof. Maybe I got lucky.

Gee, just bought one and was hoping for more circulation that was I am seeing.

I will have to keep an eye out on the shock issue.

Have a K4 for almost 2 yrs, no issues. Have only taken it out once to clean.

After I cleaned one of my K2's it now trips the breaker everytime I plug it in.

I have Koralias in all three tanks, a 1, 3, and(4) 4's. Never had a problem with any of them so far(1-3yrs).

Do they make alot of noise when they come on? I gave up and put mine on 24/7 the noise on startup was driving me nuts. I mangeged to quiet it down significantly by putting a small piece of silicone tubing on the impeller shaft to keep the impeller bounce down.
