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....

Arrived but can't use as it is not a UK plug, finally got a conversion plug, gutted in tank, was extremely noisy then stopped working, obviously faulty, very unhappy!!!

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

It was good but was quite loud and died quickly. I had 2 running and had to swap it out for another model.

Bought for a 300ltr fish tank, very good flow pump & also quiet.

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..

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.

I absolutely love this bubble ! We've been using this very same one for a little over a year and still works like new! We purchased another one recently just in case, cause you never know 😉 I have it in my cichlid 60 gallon tank. We place it in the middle of the tank so it distributes the waves evenly. I prefer this over the air stones and regualr bubbles because it mimics river waves.

Vale la pena el costo del producto, funciona excelentemente.

Elle vient renforcer le brassage de mon bac de 360 L Malawi. J'avais déjà une CP4 . Produit facile d'entretien et silencieux.

meine fische freuen sich und hab grad ne zweite bestellt :) bringt echt ne super Strömung aber war für mein 1000l Becken zu wenig

Built strong, no rattling Quiet and efficient. And also it’s amazing , in just one night all the fish poop on the sand was all gone by the morning was swept away by the current into the filter.
