Is it possible to have the dimensioning for these pomps ? Thanks in advantage

Hello, K Evo can be used with any timer and we suggest intervals of minimum 5 second. The lifetime of the pump will not decrease even if used at such short interval because it is provided with a specially designed rubber bomber to absorb vibrations.

Hello, it sounds as if you have a faulty pressure reducer. Please return it with the warranty to the shop where you purchased it and have it exchanged with a new one.

Hello, the Ario should work, but it might not deliver the same amount of air as it would if positioned at the correct depth (the venturi principal that creates the depression that sucks in the air is influenced when depth is increased)

Hello, In ref to the Wavemaker, please make sure that the product is positioned so that there is enough air exchange and the temperature is not to high, this will prevent the fan from going on too often. Aslo, make sure that the fan is clean and free of dust. In ref to the Koralia 3 making a humming noise, please make sure that the two bushings are positioned correctly, one should be on the rotor (white one) and one should be at the bottom of the rotor chamber (black one).

Hello, our 12Volt pumps are designed to work only connected to one of our Wavemakers (the connectors are not universal). If you want a Nano at constant flow rate you should buy a 220V model.

Qualcuno può darmi dei consigli sul settaggio ottimale di questo apparecchio ? Ho un acquario marino di bariera con 3 pompe....2 koralia 4 e una koralia 5. Grazie

Hi Hydor, I've bought a pump nano0 12 Volt. I'd like to use that pumps without wave marker. How can I do that? Have I to buy a transformer 220->12 Volt AC? Thanks. Regards.

Hi I have 1 set including 4 pumps running and the two small model 3 make a lot of humming noise when at full speed. Fan i wavemaker also has lot of noise. System must be shut off when we sleep in house even though aquarium is 20meters and two doors away! Can wavemaker fan be changed to better an are pumps this noisy???

I have purchased an Ario 4 for a new tank I am setting up. Unfortunately, I didn't realise there was a restriction on the depth of water in to which it can go and my new tank is quite tall!! Can you explain why there is a restriction? And what would be the problems if I was just to run it at about 60cm depth? Thank you, Gary.
