The design of the Fluval ramp timer is garbage, but I'm using one with my Aquasky lights anyway. My menu button and down button work (the up button 'worked' for about two presses
), so if you don't mind scrolling forever it's not terribly difficult to set and works very well afterwards.
The Current USA ramp timers should work with them as well, and they seem to get much better reviews! I would have gone with one originally, but I wanted to get a timer set up before leaving on a vacation and the LFS
only stocks the Fluval ramp timer and basic on-or-off models.
