The tropical theme sounds very relaxing and quite fabulous! The
LR resting on the
DT glass bottom will give it support and help keep it from shifting as it would if it were just resting on sand. The reason why some prefer to use the
PVC support method is to raise the
LR above the sand bed giving water ciculation to all of the
LR surface areas which helps remove an accumulation of possible detrious build-up. If you choose to place the
LR on the glass bottom, you just need to provide water circulation to the base of the exposed rock to keep detrious from getting caught between the sand and rock as heavier particles in the water collumn will settle and become lodged there. It really depends on how much maintenance or time one is willing to spend in maintaining their system.
IMHO of course. To my knowledge, persons putting the
PVC method into practice have been well pleased with the outcome and I have not heard of any negative comments as of yet.
