You should be fine with those plants. If your not seeing the growth you want DO NOT use max, you WILL grow algae unless you use pressurized co2 or DIY co2. Instead I'd recommend using whites on 50-70%, reds on 50-60%, greens on 40-60%, and blues on 20-30%. For the higher end of all these levels you would do this by pressing the "w" button, then white down arrow 3 times, then red arrow up 7 times, then green arrow up 6 times, and blue arrow up 3 times. After hitting the "w" button DO NOT hit any of the other max color buttons. Press on one of the "M" buttons to save the progeam. This is similar to how I run the 24/7 in my high tech 29 gallon, in a taller 55 gallon you should be fine with the %s I gave you.
