Hi,I am thinking of going with a 5"-6" dsb in my new 125g reef but a lot of people over here in the UK are telling me that it is not always the best way to go as debris can collect under the LR and can not always be siphoned out when doing water change if it is in difficult to reach areas as you do not want to stir up the sand.How do you guys using dsb`s avoid this problem.My guess is i could hide some powerheads behind LR and attatch spray bars to ensure debris does not get stuck but i would like to hear your more knowledgeable suggestions. THANKS
