is 2x65w light enough for a 75g? I'm not too experienced with the bigger tanks.
I think what you really want is some aquascaping help. First of all, plants popping out randomly in the foreground will never be ok . . . especially swords. To make the foreground strong, I would designate a triangular portion of it to be the foreground, and the big plants should be moved back out of it.
Well, you get the idea, this is crude but . . . you may see in my drawing that the right side is larger than the other-- well this is a way to use the
2/3 ration, the "golden ration" that is balanced to the human eye. There is a thread here with a really good deeper tutorial on that but . . . anyway, this is a basic easy lay out to follow. Basically, the foreground can be bare, possess small plants, or even some medium or fine-leafed larger ones when used tactfully. For sake of simplicity and ease, I would keep it bare but spread those microswords of yours out so they have a chance to fill in the foreground.
The mid ground sets the structure of the tank, and the rocks and wood used to build it should set up the structure of the tank. Anubias and javaferns are key players in a lot of tanks in the mid ground, because they are un-obtrusive for the most part (though keep an eye on those ferns) and they dress the mid ground plants which are also important for structure.
Background planting should be done with an eye to break up symmetry. Try to make the two sides of the background distinctly different. Trimming is vital to getting attractive bushy growth from stem plants.
Well these are some simple instructions, though if you follow this there isn't much room for creativity. However, from your post I'm getting that you just want help, and not irritating artistic theory support and me acting like an art teachers saying "Push yourself! Figure it out on your own!"
