i upgraded my 75gal to a 90gal about a year and a half ago and am finally getting around to reefscaping it. The problem is i always sucked at reefscaping and would just stack the rocks any which way. This time though i wanted to make a solid nice reef. I had some liverock that i took out of the old aquarium 5 years ago and decided to use that since it is dried out now and it is easier to reefscape dry,cycle it, then added it to the tank. Anyway here is my progress for the left side by the over flow. The problem is i have alot of rubble that i bought and i keep adding to the structure and I don’t know when I should stop.
