Can I remove the front display panel on my Aquaero 5 Pro to make a Aquaero 5 LT ?
Yes, you can remove the display module from the aquaero 5, and using standoffs mount the unit against any bulkhead.
If you wanted to get a newer controller, I would suggest the OCTO (Unless the fans are power modulated, or you are using some of the more esoteric features of an aquaero).
