Could I get some feedback on the AI Hydra 52's vs the 52HD and the Radion 3rd gen vs the pro? I have researched for days and just dont know which to choose. Tank is 100g 4 feet wide 24 in deep. I apologize if this has been asked before, for some reason i am unable to search previous threads easily on my phone.

I currently run AI sols, AI no longer carries the conversion kit to Hydras, I have searched and cannot find where I can buy a conversion kit. If feedback provides that the regular hydras will do the trick vs the Radions, I'd rather just spend 600 bucks and upgrade!

Thanks for the feedback, much appreciated!
