hydro koralia question

[1628mna]

i was just on the marine depot web site. i had seen the hydro koralia powerhead and i was wondering how they run? are they noisey? and is there anywhere else better/cheaper to get them?



thanx in advance

They are not noisy when they are running. You cannot hear them while running. They do chatter for a few seconds during start.

In looking around I came to believe that these were the best for the money. I was originally going to buy Tunze 6055 nanostreams and controller but gave up after waiting a year for them.
I'm hoping someone comes out with a variable speed controller for the Koralias

My #4 chatters during start up but my #2 doesnt. I also have them on a RS wavemaker. I think I figured out a way to stop the chatter. If it works I will post again.

Mine used to chatter after a cleaning once. I found out one of the little washers under the prop fell out. Replaced it with a teflon washer and it was quiet again.

Good pumps. They make good water movement and are noise free.

Mine didnt have washers, but thats what I was going to do.

im also ordering a gate valve from marine depot. im sold on the hydros though the gate vales(1 inch slip $33.00) seems a little expensive! no/yes?

[usmc121581]

Yes I get all my plumbing from HD or lowes.

[1628mna]

the hd by me doesnt carry gate valves, plus the guy that works in plumbing is a real idiot. does lowes carry them?

You can get 1"gate valves here:

I added a #3 Christmas Day and I love it.

they chatter when they start up because when they get electricity to the magnets they tend to not only spin the propeller but to push it outward on their support shaft, it could be fixed if you put a piece of 1/8" tubing, taking the space between the front of propeller and top of cage housing of powerhead, havent tried it yet, but will post results later.

I own two #3s and LIKE THEM ALOT! No noise when running. Very easy to direct flow.
