NEW Red Sea 4-Part Complete Reef Care

Red Sea 4 Part Complete Reef Care

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

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.

NEW Red Sea ReefCans

Volume 18L, H x W x D 55 x 9 x 44cm

Volume 40L, H x W x D 55 x 17 x 50cm

Are you struggling to find a good spot for your top-off reservoir?

No worries, Red Sea’s new ReefCans contain more RO water while taking up less valuable floor space, and are designed with ReefATO+ users in mind.

The ReefCans 18 & 40 can supply a 200-liter & 500-liter tank with enough RO water for about a week. They have a transparent plastic body with an embedded water scale, can fit in the sump cabinet or behind the tank, and have a separate back opening designated for the ReefATO+ pump, tubing, and power cable, with a cap designed to hold the ReefATO+ siphon breaker.
