Forum » Hydor Color 4

Hi there I am having a problem with a blue Hydor Color 4 unit - this is the second unit I have got and had fail on me within a year. It stops working completely - no aeration or light. Is this normal? I don't want to go spending money on another unit just to have it fail on me again. Can you advise if there is anything that can be done regarding this.

Dear Customer, thank you for your contact. It is very strange that Ario Color 4 stops working completely. In this case, you can clean it and control if every single part of the unit is undamaged. In particular, we suggest you check if the Ario is correctly connected to the electric supply, or if the air pump is damaged or positioned at the correct depth. You can also check if the air control is blocked or partially closed, and if the unit is correctly positioned (some gravel can accidentally block the pre-filter). Hope this helps!
