Fluval Sea CP4 Flow Pump 5200L/h

I have an 800 litre tropical freshwater aquarium with an eheim pro 3 1200xl and a 1200 lph internal filter. With the decor in my tank and the relatively high stocking I needed something to complete the circulation. This is perfect. I've got it about halfway up my tank pointing upwards and it creates just the right amount of water movement to keep the water surface moving well and get any debris into my filter intakes. I considered cheaper options but am pleased I spent a bit more as this is silent, well built and works well.

OMG. Since I installed this unit and adjusted the angle of the stream every few days, my 300 ltr tank is staying cleaner for longer.Don’t buy to powerful unit for your tank and you will be well pleased with this unit.My only criticism is that when it starts up, it makes a loud clunky noise which disturbeds the fish and ME......Recommended keep your tank cleaner for longer....

When I installed this it worked fine. I've had it less than 18 months and it doesn't circulate any more............it sucks!There is clearly an issue which causes the impeller to draw the water in through the front and out the sides. Needless to say, it no longer circulates. I expect greater longevity from a name like fluval.

Does a good job good power and quite when put on right

It was dead quiet in the water on the first day.It is not so quiet any more after a few days - it gives off distinct buzzz, more notable than my old Fluval 406 canister filter.It has 2m cord with UK plug....longer than mentioned in some of the reviews.I was initially worried that the CP4 has too big flowrate for my 330L tank. It doesen't, the fish and the plants could actually tolerate even higher flowrate.

I am using this to provide more circulation in a heavily planted 630L freshwater tropical aquarium which only pumps from one side to the other using the standard sump pump.All in all I am very impressed with this product, it is extremely powerful and provides a playground for some of my faster fish. The pump is completely quiet and cannot even be heard with all of the other pumps turned off. I ran this out of the water and again it was almost silent. There are three strong suction pads on the back to hold it onto the glass that hold VERY hard so there is no worries about it disattaching itself and make it easy to move around to get into the desired position. This pump states it runs at only 7 watts which is lower than others I have used. I could not recommend this product anymore.

Brilliant piece of kit. Not a fault, brilliant power and comes with a 2 year warranty. You definitely get what you pay for with this thing.

This is an excellent product. Went for Fluval due to quality and not let down with this...Needed something with a strong flow to assist circulating/cleaning my plec tank and this is awesome. quite and easy to direct where you want it...It may be more expensive than a lot of others but theres a reason for that..

Just fired it up, aimed it at the halfway point of my 125G Peacock Cichlid aquarium and it has the perfect amount of power. I'm getting a very nice clockwise circulation, the debris is going towards my FX6 filter intake. The three suction cups hold it in position just fine. Motor is silent. Overall, I'm a happy customer!

Vale la pena el costo del producto, funciona excelentemente.

Definitely worth the money put it in my 55 gallon tank and it works wonders powerful and reliable
