Help with rocks

[Devildoc]

This is a 240 gallon system with 75 gallon sump. I'm not for sure if I have enough rock or not in my system. I have took 3 pictures of my rock work for you.. Height of the tank is 27inches and 24inches wide. Everything is growing OK,but not how they should be. To get a good par on the ends I have to drop my two 120 razors almost 4 inches off the top of my water. Any suggestions would be great thanks. Oh and forgive the brown sand rodi filter went out so had bad batchs of water for the last month.

Rock looks a little light. I've got a 225 with about 200lbs in it.

Thats what I thought as well it should fill in higher and all the way across shouldn't it? While still providing hiding places

I'm sure you can have less rock, but I like as much rock in my tank as possible.
Tank looks great by the way!
