What I've learned about this tank and future tanks (so far).
#1 -- I'm going to be getting a new sump. Maybe not soon, but eventually. The model I purchased (ESHOPPS R-300) has the return pump in the back. I have to get on my hands and knees and stick my head way in the back of the stand to check it out. You do this a couple times and you realize the mistake. I'm either going with a different model or am making my own -- will decide that in the future. For now it works.
#2 -- I am 5'5" tall. I cannot reach the bottom of the display tank -- even when I stand on a step stool. I have grabbers I use, but they do not pick up rocks well. Because I can't reach the bottom, I have to pull out the rocks to glue on the corals instead of placing them in the tank. There is no way I can reach down that far without a snorkel. If I did it again, I would have gone with a smaller tank height. Although I do love the size when I'm not submerged.
