I am setting up a 125g reef at my office. I have found with the dollar being what it is that alot of money can be saved going cross border.
Which online Aquatic stores do you use.
I have been using www.customaquatics.com
I have found them top notch. great service and great prices. They however, don't carry some of the items I am looking for. So hence this post.
