I just ordered one for my hydra 32 from 3Dreefing for the heck of it and see what good it does. Is the prismatic diffuser sheet that comes with it as good as it gets? Is there better that I can replace it with?

I believe the radions use the frosted as well on their diffusers. Might have to get some and see if there’s a difference compared to what comes with the diffuser. I’ll have a par meter as well when I do all this.Not that I found. This guy built his own from P95 frosted acrylic.

AI Hydra HD diffuser - New design
Finally figured something out on how to make a diffuser for my AI Hydra 26 HD since there’s nothing on the market at the moment. The difference it makes is night and day, seriously. The shimmer is so calming and soft it’s insane, no more crazy colors on the sand which honestly takes a toll on you...www.nano-reef.com
Yes, the Radion diffuser is a polymer bracket with a thin frosted sheet that attaches via 4 magnets (the attachment method is a blessing when taking it off and a curse when you're cleaning and accidentally knock the diffuser into the tank). That thin sheet does cut PAR back by probably 10-15% and I don't get as much of the 'shimmering' effect).I believe the radions use the frosted as well on their diffusers.
