My favorite pump for boosting circulation is the Koralia by Hydor of Italy. These are so popular they are hard to get and keep in stock. My supplier recently filled only half my order after waiting two months to get them. I have the following in stock now, subject to prior sale.

4 - #1 - 400 gph - $34
4 - #2 - 600 gph - $39
3 - #3 - 850 gph - $45
6 - #4 - 1200 gph - $54

Our price includes shipping in the continental US. Alaska and Hawaii please e-mail for additional shipping cost.

very cool.. these pretty darn good prices.. thanks for posting the details

Hey Dick great prices. I need to get a #4. Is that still in stock?

Dick, I am either going to carry those or Tunze in my store. Still trying to decide. With a typical retail markup, would these be competitively priced?

Russel ... you probably will have a hard time keeping these on the shelves !! these PH's rock !! i do not own a store, but i know how hard they are to get right now, and they have been for the last few months.

Hey Dick, do you carry the Koralia Nanos?

Normally I do but out of them and don't know when I'll be placing the next order. Sorry.

And, just to add another selling point, i disassembled all my modded Maxijets and replaced them with Koralia 3s. A modded MJ and a Koralia 3 are about the same price and the Koralias work waaaaay better. They are completely silent, whereas a modded MJ can rattle around, and the suction + magnetic attachment lets you place them anywhere without having to build clips or rely on suction cups. Lastly, they are easy to clean, not that i have to do that often, and move some serious water.

I already have all mine Dick, but if i ever upgrade my tank (fingers crossed) i will order a bunch more from you!

Thanks Samuel. I really like the Koralia pumps. I have two #3s in my 135 on a wave maker. They clatter once in awhile but not very often.

Anyone ordering a "bunch" of them (3 or more) from me ought to check with me for a better price. As you know, my price includes shipping in the lower 48 states. While there isn't a lot of room for me to move, combining multiple units helps me save on shipping.

Dick

I agree Samuel. I have a 4 in my 120 and need to get another. I was looking for an nano for, well, my nano, and didn't want to have to drop a bunch of cash on a Tunze.

They are the only pumps I will use in my tank. I only have 1 pet store out of the 6 not so local pet stores i go to. And he cannot keep them in stock either. Great product!

I tried using a wave maker with my 2 Koralia 3's and the rattle noise got to me. Is there a mode for these to keep them from rattling?

Hydor is suppose to be working out the kinks in THEIR wavemaker that is designed specificly for the Korallia pump. it is to hard on them to start and stop all of the time, so the wavemaker they are making is the type that lowers and raises the prop speed.

The only way to slow the prop down would be reduce the voltage to the motor. AC motors dont usually tolerate this well unless they are specifically designed for it, especially in rapid changes. Hopefully they planned well for this feature.

Found one at the LFS. Thanks for checking Dick. I need to order another #4 soon.

I thought the same thing about the voltage, I haven't seen a wave maker from hydor so I assume it hasnt happened yet. I wasn't sure if thier was a way to put some kind of spacer in the pump to keep it from slapping when it came on.

On another note i remember visiting hydors site about 4 months ago when i bought the pumps and it was in english. now i believe its in italian, did they get bought out recently or something?

Hey Dick! :love!:

Got some Qs for you. I have the 90g with the standard return from my tower. I have purchased a "T line" to disperse water towards both sides of the tank as the flow isn't what it's suppose to be. The LSF hasn't come out yet to take the single off and add the T. (They want to do it because they're afraid I'll mess the pipe to the bulk head up. And you know the story behind that nightmare.) I currently have a wavemaker on the other end. What size/how many of these pumps, would you recommend for my tank?

Good Morning Everyone,

They are the only pumps I will use in my tank. I only have 1 pet store out of the 6 not so local pet stores i go to. And he cannot keep them in stock either. Great product!
They are popular, no doubt about that. For the money, they can't be beat. We have them in stock at this time, with the exception of the Nano size.

I tried using a wave maker with my 2 Koralia 3's and the rattle noise got to me. Is there a mode for these to keep them from rattling?
I put up with the rattle for several months and realized one day they didn't rattle anymore. I noticed the impeller is covered with a thin coat of algae. I wonder if that is the difference? It may have slowed them down a bit. Not sure though because they still move a lot of water.

I heard this too but, haven't had any updates that I'm aware of.

I would think they are aware of this, if that's the case.

Glad you found the Nano. I've got a few of the other sizes. My supplier shorted me half the order on Koralias. I called them when they came in and he said they have to spread them around. :huh: Oh well.

I thought the same thing about the voltage, I haven't seen a wave maker from hydor so I assume it hasnt happened yet. I wasn't sure if thier was a way to put some kind of spacer in the pump to keep it from slapping when it came on.

The slapping is caused by the opposing forces of the magnetic coupler. We all have taken a magnet and reversed ends. The Koralia's magnetic coupling is one tube inside another. When the power is switched on, the magnet "jumps" and because of the resistance of the water on the impeller, it doesn't "catch" and that causes the motor to speed up and the magnet skips several more times before it "catches" the other magnet. Does that make any sense??? It does in my mind but, may not come across correctly. :cool:

Hydor has not been sold. At the very bottom of Hydor's page is a little box for language preference. You can change it to English. :up:

I currently have a wavemaker on the other end. What size/how many of these pumps, would you recommend for my tank?
The Koralias come in 5 sizes, the Nano, #1 at 400gph, #2 at 600gph, #3 at 850gph and the #4 at 1200gph. One of the features of the Koralia pumps is the outflow is spread out instead of like a power head. Power heads push their water through a 1/2" outlet, Koralia's outlets range from 1 3/4" to 2" for the biggest one. In your case I'd suggest a #2 or #3 depending on how much flow increase you want.

You other guys with Koralia experience, what do you think about Skurvey's question?

Here is the link to my Koralia page. There's more info about the Koralia pumps there. koralia Pumps (http://www.theculturedreef.com/koralia.htm) I have limited numbers, 4 #1s, 2 #2s, 3 #3s, and 6 #4s. Prices marked include shipping in the lower 48, Alaska and Hawaii would be more. We don't ship outside the USA.

Thanks for the discussion guys and girls. Hope this helps.

Somebody didn't waste any time. The 2 #2 Koralia pumps are gone.

The rest are available.

Thanks,

Dick

Nothing like pressure. :rolleyes: Since I didn't get any more suggestions, I went on and ordered a #3. I'm sure placement is the real key. :up: I'll let you know how she works out.

Subtle pressure. LOL :love!:

Got your order Skurvey. This will go out Monday.

Thank you.

Dick

I have 2 #2's in my 54 corner plus my return. The return and and one K2 are on the left and the other K2 is on the right. Each is at a different level in the tank.

Carmie, Do you think I need 1 more?

Dick,

Do you have any the #1 left? I was thinking of of those for my nano. :D

Lori,

Unless you want to keep things that are low flow I think a second one would be good. Maybe not strictly necessary but beneficial.

Yes Lori I have a couple of #1s left. I didn't want to be the only person "selling" you on 2 #2s because, well, I'm the guy selling them. I wanted you to have other input. I agree with Carmie, two would be better than one.

Dick

I did some reading on power head flow rates with various size tanks. I actually think Rob also did a podcast about power heads. I have a 75 gal and ended up figuring 2 #3's would meet my needs acourding to what I learned doing the research. After putting them in a few months ago I noticed my corals didn't seem to look as nice when the power heads were on. So I turned them off for a couple months. Maybe a bad choice, idk. But it didn't seem to harm them at all having the power head's off. Well when I was at the LFS last week I mentioned this to them and they told me how beneficial it was for the corals to have the flow from them. So I turned them back on. One other thing and not sure if this is a bad thing but the power heads come with this little round black diffuser thing (lack of a better word) that falls off them a lot. I just took them off. I supose I could have glue them on, but I also didn't want the flow so much directed in a specific point. I liked it being able to move around more from not using the little black diffuser thingy's on the tip of the power head.

Dick, what exactly do you have left now. I purchased one #3 because I thought you were out of the #2. :D I want to get one more of something. :unsure: What to get? I don't want too much and then I don't want not enough. Sort of like Goldielocks and the 3 bears

Oh and :thanks: Tdkarl.

Lori, I think you could use 2 3's in your 90. I have 2 2's in a 54.

:master: J/K CJo ;) You think this is bad, you ought to see me in action at the drive thru. They hate me. I can't make up my mind! Ok Dick. I got a nutter one. :up:

There is a definite school of thought that says flow is as important as light, perhaps more so. Advanced Aquarist's Online Magazine - Feature Article: Water flow is more important for corals than light. Part 1. Introduction to Gas Exchange (http://www.advancedaquarist.com/2006/6/aafeature2)

10/4 Lori, They'll both go out Monday.

Thanks.

Dick

Lori, I think you will like what you see with the 2 of them.
