If you need an outside perspective to help with improving your aquascape, just post here a few shots of your tank, and will try my best shot at providing specific advise according to your goals for the tank. Sometimes I can just answer here, show the alterations using photoshop or make a video. Just post here front shots with your cellphone/camera positioned at 3 different heights (sand level, centre and water level) and also a couple of angled photos, so that I can have a better understanding of your tank's layout. This is a subject that is surprisingly not researched by most reefers and I have given some thought and some time ago I did a similar exercise in another forum. It's also a great way for everyone to learn from each other and see a few freshwater techniques that we can apply and also many others that are specific for reef tanks. In the meantime, if you want some inspiration here are a few videos I made with suggestions for different tank shapes.
