Koralia Water Circulation Pumps?

[The Shrimp X]

Does anyone use these?
Or anyone have an experiences of info on them...
they seem pretty interesting (almost a cheeper substitute for a tunze type pump)

They arent expensive and wanted to get some info on them to see if their really worht it...


Do the ball joints loosen over time making it start to just hang?


(heres a link to them)

I just bought the Koralia 4 for my tank and it works really well...
You need to position it right or it causes a sand storm. It’s very efficient.
Bought mine off a guy on ebay....

They work great. The 2's and 3's were recalled some time ago, so be careful with those. They also work on the Seio controller. I havent had any troubles with the 4's I have. Very wide flow pattern.

I'm running 2 of the 4s on a AC Jr for a wave maker. So far, I'm very impressed, especially for the price

 

[steve the plumb]

I thought I have read a thread where they can't be used with a wave maker controller.If so will you burn them out from switching off and on

 

[sherm71tank]

The Seio controller does not turn them on and off. It goes from 50% to 100% on a timer.

 

[steve the plumb]

is the seio safe to use with these pumps?Can you use any other type of controller with them wave maker or somthing like the aqua controller junior or the profilix(noy sure of spelling)I would think as long as the units are not shut off totaly then it would be considered safe.Can you hook up more than 2 pumps to the seio (split them) or do you need more than 1 controller.I may need 6 hydor #4's

I read somewhere that switching them on and off every few minutes is bad, but that running them for a longer duration is OK. If I run into any problems switching them on and off at intervals over an hour, I'll surely post it. At least they are not that expensive if I do burn one or both up

I have been using the Seio controllers with the 4's without issue. I've also used them with the Maxi-mods no problems. Don't know about other controllers.
Seio says not to use more than two pumps on their controller. I've had as many as six pumps connected at once. I looked at it this way. The Seio 2600 uses 55 watts and you can use two of them safely according to Seio on their controller. So any combination of pumps up to 55 watts per outlet should be fine. I bet you could run even more than that but I don't know how much and don't want to fry a controller just to find out. This is purely speculation on my part you should always listen to the manufacturers recommendations.

well since these pump use 8.5 watts its safe to say you can use at least 6 to 8 pumps on one controller without having any problems.I was thinking of using a dart for a close loop but 6 to 8 of these pumps would move plenty of water without much power.The only thing is I would prefer not having any pumps in the tank simply estetics.I had planned either 2 darts on my 300 gal.With 6 to 8 #4's on an 8 ft tank I will get a good flow but powerheads every where doesn't look nice and how big are they?Cost wise its not bad either. 8 pumps will cost me $480 will use 72 watts of power and will move 9600 GPH of water.2 dart pumps $460 use 320 watts and move 5640 GPH of water.Whats a better choice?That or go with a stronger pump wich will still cost between $350-$400 and use a good 350 watts of power.Plus drilling tank and bulkheads,fittings,and flex pipe.

 

[sherm71tank]

The 4's are 12 watts.

 

[steve the plumb]

marine depot lists them at 8.5 but even at 12 watts you are looking at 96 watts to move 9600 GPH of water,not bad

 

[sherm71tank]

Agreed, I pulled my Seio Superflow pumps out and went with the 4's instead. If you are looking for a wide flow pattern they are very hard to beat. If you need more of a concentrated stream they are not what you are looking for.

 

[steve the plumb]

the seio's are large.I have 2 x 860 and 1x1100 plus 6 mj un modded.In my new tank I will more than likely use the 4's.For the money and low wattage its better to use these pumps VS a close loop.I still prefer the close loop for estetics but maybe it can figur out a way to make the pumps blend in better.Who knows.I am looking for flow in a reef tank prefer wider.I can hook up 4 pumps to one side for to the other or get 2 seio contrllers or get a controller like the aqua junior that does more than just pumps.

I would get 5 of the Koralia model 4's. Put one in each of the four corners of your tank and aim them at each other in an "X" pattern (i.e.-the right front corner aims at the left rear corner and vice versa) and I would put the last one right in the middle of your tank on the back side aimed straight ahead blasting the front of the tank so even if the flow from the corners didn't spread all the way across your tank from corner to corner the middle one would make up for that and you'd have flow evenly dispersed throughout your tank .
