Anyone have issues with these things? Ive had one for less than a year and its dead as a doornail. Not only that but I suspect it was the source of stray voltage in my tank... Its a 4, and in my opinion, a piece of junk! Has anyone had luck trying to get one replaced by the manufacturer? I hate spending good money on something so hyped up only to find that its nothing but s-crap...

I haven't heard anything good about those. I have a Tunze and haven't had any problems. I'd definitely recommend one.

I got rid of mine I didnt like them at all, and I think it was leaking voltage also. They are loud and get stuck all the time.

Be careful Koralia users!..

I have had 3 of them in 2 tanks, and they work great. i have had them leak voltage in the tank, but it doesn't seem to hurt anything. 1 i bought new and is now a year and a half old. it is not leaking current and works. 2 k4 I bought used and they leak a small amount of current. If you are comparing them to tunze anything you are living on a different planet. K4's new are about 50-60 bucks, and you won't find an off the shelf powerhead that will move water like that w/o mod's, and for that price. Tunze powerheads that move that kind of water(1200gph) will cost you about 4 times the price. I personally would rather buy a brand new k4 ever year for 4 years. It gives me another reason to go to the fish store!

Best econo powerhead out there!!! I know I am cheeeeeaaaaap! hahaha!

I have a question for everyone; Is everyone using these or other submersible pumps on GFCI receptacles? If not please do so, not just to protect your fish but yourself also.

No more Koralias for me... I really like the Maxi mods though, for the money they cant be beat...

i just bought a used setup last night came with 2 k1's how do i check if they leak current,

Volt meter, One lead in the water, the other to a ground point, A/C voltage... If theres voltage present, youll know it when you stick your fingers in the tank, specially if youre bare foot..
