Question: 

 

What size aquarium will the AI Hydra Flex arm fit?

 

 

Answer: 

 

The 18" AI Flex arm will fit aquariums between 45cm and 60cm wide. This will allow for the light to be positioned half way and still be approximately 30cm above the aquarium.

These brackets will fit the Hydra HD 26/32 and 52/64.
