Hydor Koralia 3G flow issue
 

I am interested in purchasing a couple of Hydor Koralia 3G power heads but have been put off by a number of poor reviews on amazon 25% of ratings were just 1 star. Most cited a problem with dimiinishing flow over a short time period that would be reset by cycling power.

Can anyone provide an explanation ? Has this problem been addressed in the current inventory?

Where is the customer service from Hydor?

I just purchased one of these with the intent of adding another and a controller, if this is a long term issue I boulder if a controller would take care of the power cycle as it operates. I believe the g3 were designed to be ran with a controller.

Wow, over a month from the op Question and still no response from the OEM,

Exactly!!! Please learn from me!! Unless you like to learn the hard way!!! Hydor does NOT help. They do NOT offer support and they do NOT back up their products. All my hydor products failed within the year and they did NOT refund me. Spent several hundreds bucks on their garbage products and not a single of them is in service right now!!!

I have not had any issues with these.
