Some people just have to buy the "status quo" to feel good about themselves
a bit out of line don't you think? Sorry i want my system to look good and not be cluttered with powerheads that are 10" long?
If you want a powerhead that pushes water, then by all means, they are fine. I ran my tank with moded maxi-jets for a while which are very similar to koralias, and one of my good buddies had two big koralias in his tank and it worked well.
All i'm saying is that the OP was asking for opinions, i gave him mine. No, i have never owned a koralia simply because i didn't want a jet engine in my tank, which is the same reason i went vortech over tunze. It's nothing personal, just not what i found impressive or the quality i wanted in my system... and i think the original poster thought the same thing?
Like i always say in this hobby, you get what you pay for.. there's a reason why they are cheaper, and it's not because they aren't "brand name" because the name "koralia" is probably known by more hobbyist than tunze or vortech, simply because it's at a much more attractive price point to incoming hobbyists.
If you don't want to shell out cash on quality equipment, then that's fine.. this hobby is all about enjoyment, but don't bash the people that do, and don't think they are boosting their ego when they are backing their product because they feel it is the best on the market.
