What's the Diameter for the Red Sea Max Nano return nozzle?

[Goodersgold]

I'm looking to plug a return nozzle splitter on my Max Nano return pump outlet nozzle, to spread flow around the tank but I can't (unless I poke about in the tank) find the diameter of the nozzle anywhere. Can you help please. Thank you

Why exactly would you want to block the only return for the return pump?

They are all metric, I know on my RSR170 it’s 25mm so it might be the same?

Not plug as in close off lol, maybe the word connect would have been more appropriate!

Ah. As those are for your return pumps, I would probably lean towards adding a wavemaker to augment your flow instead. Something like a Nero 3.

I actually think its 16mm, 5/8" ,,,if you dont get a definitive answer by tomorrow i will go and measure it for you

Indeed, good advice. I already have a Nero 3 in place, but I would like to increase the agitation at the surface to improve the gas exchange, my Ph is hovering around 7.8/.9 and would like this a little higher.
