From now until 11:59 p.m. on memorial day we will have a 30% discount on all of our marine aquarium products. To take advantage of the discount, simply use the code "memorialday", during checkout. If you placed an order already this week, you can add to your order by choosing the free shipping option "group buy" during checkout, and by leaving us a note about your previous order. We apologize in advance for all of you who made purchases before the sale, but we cannot apply it retroactively. This offer cannot be combined with any other discounts.
