It delivers elevated, biologically balanced levels of the foundation elements (calcium, magnesium, bicarbonates) needed for sustainable, accelerated coral growth, plus the full complement of trace elements carried in salt harvested from Red Sea reef waters. Available in a 7 kg bucket (210 L \/ 55 gal) and a 22 kg bucket (660 L \/ 175 gal) — pick your size on this page.\u003c\/p\u003e\n\n\u003cdiv style=\"position:relative;padding-bottom:56.25%;height:0;overflow:hidden;max-width:100%;margin:20px 0;\"\u003e\n\u003ciframe src=\"https:\/\/www.youtube.com\/embed\/RAWwff287C0\" title=\"How to mix perfect seawater from Red Sea Coral Pro Salt - mixing guide\" loading=\"lazy\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen style=\"position:absolute;top:0;left:0;width:100%;height:100%;border:0;\"\u003e\u003c\/iframe\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eThe boosted salt for coral growth\u003c\/h2\u003e\n\u003cp\u003eRed Sea's research shows that the precise ratio between calcium, magnesium and carbonates is what lets corals efficiently take up these elements and build a robust aragonite skeleton. Coral Pro is formulated to those ideal ratios: combined with Red Sea's reef care recipes, it supports growth up to four times the natural rate. Its 12 dKH alkalinity makes it ideal for mixed reefs and SPS frag tanks, while keeping LPS and soft corals looking their best. The improved formula dissolves in about 20 minutes, from bucket to tank.\u003c\/p\u003e\n\n\u003ch2\u003eBatch-guaranteed parameters — MyBatch\u003c\/h2\u003e\n\u003cp\u003eRed Sea does not publish its calcium, magnesium and alkalinity ranges as text on its product page: the guaranteed values are printed on every bucket and verifiable batch by batch. Using your bucket's barcode, Red Sea's MyBatch service gives you the exact lab analysis of your own batch. If you see numbered ranges elsewhere on the web, they don't necessarily describe the batch you receive. Need help reading your analysis?

It's a boosted salt: every water change tops up calcium, magnesium and alkalinity a little, keeping parameters acceptable without a dosing program. It's not perfect stability — it can create small spikes — so for that profile we recommend one water change per week with freshly mixed Coral Pro. For maximum stability with separate dosing, go with the blue bucket.\u003c\/p\u003e\n\n\u003ch2\u003eWhy buy from ReefSolution\u003c\/h2\u003e\n\u003cp\u003eAuthorized Red Sea dealer in Canada, with French and English support and in-store pickup in Laval.

The 7 kg (210 L) is the size made for small volumes: with 10% weekly changes on a nano, it lasts months without the salt sitting open too long.\u003c\/p\u003e\n\n\u003ch3\u003eWhy does my Coral Pro mix turn cloudy?\u003c\/h3\u003e\n\u003cp\u003eA white haze is precipitated calcium carbonate, a natural and harmless phenomenon per Red Sea. To limit it: don't mix for more than 2 hours, don't bubble air, don't overheat the water, and use the mix within 12 hours.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's the difference between Coral Pro and the blue bucket?\u003c\/h3\u003e\n\u003cp\u003eCoral Pro runs 12 dKH with boosted levels that top up parameters at every water change; the blue bucket runs 8 dKH and aims for stability with separate dosing.
