Hi Dear Professor, I will apologize first because translated by Google, you've got me for a long time I read most content, and the reason for keeping corals in my country is so expensive you have a great help to me, I have a plan I invented the screen with all the properties of light and water flow standard, I wanted to ask that this plan is right or not? I'm fine particles of silica stone to a page hugged، many thanks in advance for your answer
