On my 75, I got the aqueon modular LED
48". It comes with one white bank, and built in 6 blue LED
moon. At the same time I picked up a red bank. I have been very pleased with it and is lasting very good. I do have one issue that is not their fault. It is a simple rocker switch for light or moon (nicely rubber coated though). If you use a timer you can see the predicament. The timer won't reach up and flick the switch to moon. and vice versa. LOL.
I have an Aquatic life Edge on a 55, program does it all including sunrise sunset. You can get quite involved with $$ without realizing it, as I did with the Aqueon. $119 for the light but then I added $38 for the red bank. For another $60 I could have had another Edge!!
On a side note, don't ever buy an Aqueon LED
bubble wand. In another 55 I have straight LED
white but wanted moon, so I grabbed one of these. Dual bubble/blue LED
moon about a foot long. Great. Until lately THREE of the LEDs have laid to rest out of 8. I'm pissed!
