Coral Box QP16 Help Required
 

Hi, I’m seeking some advice on setting these things up.

I am upgrading my tank to a 52” x 28” x 16”. Owing to Covid supply issues it was built with 3/4” thick sides. Magnet strength and thickness of glass pushed me from the QP 9s I have in the 75 gallon to the QP 16.

I’m having problems dialling back the flow - on reef mode it is like a maelstrom in there. There are flow and frequency adjustments, the flow seems to make sense, but the frequency isn’t so obvious..

I can dial it down to 1 for flow and do whatever I like with the frequency, and it seems to make no difference to the flow.

Any wisdom from out there would be much appreciated..

Thanks,
Rob.
