What is Seachem Reef Carbonate?

Seachem Reef Carbonate is a concentrated (4,000 meq/L) blend of carbonate and bicarbonate salts designed to restore and maintain alkalinity in saltwater aquariums. There are few factors more important for a growing reef than levels of carbonate and calcium. If either levels drop, coral growth will cease, followed by a rapid decline in health and, eventually, death. To prevent this, carbonates (in the form of Seachem Reef Carbonate) and calcium (in the form of Seachem Reef Advantage Calcium) need to be dosed reguarly.

What sets Seachem Reef Carbonate apart from alternatives?

Unlike other competing carbonate products that are predominantly made up of sodium bicarbonate, Seachem Reef Carbonate is made with an optimised blend of carbonate and bicarbonate salts. These salts raise alkalinity to a pH of 9.0 in saltwater - a higher pH than competing carbonate products. Seachem Reef Carbonate also helps to stabilise pH and stop it dropping below 8.4-8.3.

If used as directed, Seachem Reef Carbonate will not deplete calcium, magnesium, or strontium. These elements typically precipitate with increasing alkalinity, but not when Seachem Reef Carbonate is used. Alkalinity in saltwater awuarums should be maintained at 3-6 meq/L (8-17 dKH) and not be allowed to fall below 2 meq/L.

How do I use Seachem Reef Carbonate?

Simply add one capful (5ml) of Seachem Reef Carbonate for every 80L of water, twice a week. It's recommended that you add the dose to a cup of freshwater, diluting it, before adding it to your aquarium. You should also check your alkalinity every two weeks and adjust the amount and frequency of your doses accordingly. Each 5ml dose will raise alkalinity by ~0.25 meq/L. Do not dose more than 20ml per 80L of water per day.
