Refugiums are extremely popular among reef hobbyists and rightfully so, as they are a great method for nutrient export. CaribSea has introduce a refugium kit named A.R.K. that contains everything you need to start your very own refugium. The kit comes bundled together is a plastic tub and inside you’ll find sand, miracle mud, calcium carbonate rubble, Purple Up, and Aquabiotic products. The interesting part of all of this is that Caribsea is bundling rubble, which is a product they do not offer separately through their distribution channels. Retail pricing is expected to come in around $90 for the complete kit and you’ll be able to find it at saltwater aquarium stores that carry CaribSea products. We have additional immergy below the break of the inside of the bucket.
