My Iphone takes pretty terrible pictures. I know the corals look kind of bleached in some of the photos but its just the camera not being able to cope with the amount of light. I wish I could take pictures with just the blues on so you could see the colors. I need to invest in a camera. Hanvdo.... You can't drill the sides. Those are tempered. I called the manufacturer and the bottom can be drilled. Just make sure you do it slowly. Space is def. an issue. If i could do it again, I would have tried to remove the glass that seperrates the return space from the overflow. I almost had to scrap the whole project, but thankfully was able to fit enough reducers in to get it to fit the stock return ends. I've been debating adding a pump to increase flow. I feel like there is a big dead spot underneath the arch, but its always a work in progress.
