Will the Red Sea 90 & 50 mount on standard rimed aquariums safely?
Question by: Marian on Jan 18, 2020, 5:29 AM
Hey there!

Unfortunately the Red Sea mounts are only compatible with rimless tanks. Their clamp does not open far enough to fit over the rim.

Take care

I’m looking at purchasing the ai prime hydra 64 and need a mount. The ai has poor reviews. I’ve read the Red Sea Mount is also comparable. I have an innovative marine sr60. 36x24 I was told one hydra 64. Would be good. What do you recommend for the mount ?

Hey there!

Unfortuatenly the Red Sea mount is specific to that light and will not work with a Hydra. Honestly we have no problem with the AI mounts here at BRS and we are using over a dozen of them.
