thats what i thought. I have 5 emp. 400's running right now and I keep half of the baskets full of cereamic or biomax cylinders.. the others I keep ready for emergency media like phosphate removers and stuff.. thanks for the speedy reply
 
i have a penguin 350 on my 100g also with a mag 350 and I dont like the penguin.... I would go with a AC110 instead
