Meet the new 4-part Complete Reef Care, providing hobbyists with more convenience at no extra cost, and ensuring optimal coral growth and vivid colours with only one test per week!

Our long-term research has revealed that in most reef systems without refugium, the Major, Minor, and Trace elements and even the Alkalinity components are used up in a relatively fixed ratio.

Since Calcium is the key indicator of coral growth, the 4-part program revolves around a single weekly measurement of Calcium, which determines the dosages of all 4 parts.

The new Complete Reef Care is available in 3 sizes, to fit all system sizes. It is formulated so all 4 parts are used up at the same time, and if supplemented via Red Sea’s ReefDose, the hobbyist needs only to set their Calcium dose and ReefDose does the rest, which is super convenient.

The new Complete Reef Care is chemically identical to our original 7-part program and provides the same great results, however, systems with refugium should use Red Sea’s 7-part RCP to properly maintain all elements.

Very thin and comfortable. Wash well.
Very thin sock if that is what you are looking for. They stay up and wash well. There is a toe seam but you can position it out of the way

So comfy and just the right size
These are the cutest most versatile socks. The weave is just right, not too thick or thin. They don't fall or shift down your heel while walking in shoes. They launder exceptionally well. The height on the ankle is perfect for jeans, business casual pants or a quick change into gym clothes. I need more.

Cute and comfortable
This six-pack of ankle socks is a great value. All of the colors are useful to me and go well with a variety of clothes. The ruffle around the top and the nice detailed knit pattern make them very cute! The fabric is stretchy and comfortable. Mostly cotton, they did seem to shrink a little bit in the wash (I machine-washed in cold water and tumbled dry on low) but they are stretchy enough that they still fit my size 8 feet just fine. See photo, brown are new, blue have gone through the wash.
