ReefCleaners.org is having a Black Friday sale today, it is 15% off the entire store, with the exception of our rock. Rock is sale priced today though. Sale ends tonight at 11:59pm PST. To take advantage of the sale, use the discount code "blackfriday" during checkout. Unfortunately this discount cannot be retroactively applied to an order, you can add to a previously made order by checking the group buy option during checkout and leaving the note "combine with previous order" in the comments field found immediately before the confirm order button. Thanks again! Hope everyone had a safe and happy Thanksgiving! Keep an eye out for the Ugly Tank Contest that resumes later this week. (Just a quick note, our Monday shipment will book pretty early this week because of a holiday related backlog. I apologize for that).
