Delta Rock

Introducing Delta Rock, Engineered Reef Rock for your reef aquariums, manufactured and supplied by Delta Aquatics International. It is reef safe, Eco-friendly and extremely porous, this allows for the optimal growth of beneficial bacteria ensuring a superior biological filter. Due to its porosity it is extremely light, which means you get more rock per kg shipped. It contains natural calcium carbonate that promotes skeletal growth in corals ensuring any tank that contains Delta Rock thrives!

Recommended ROCK to WATER ratio for acceptable water parameters is 1kg:10litres

For optimal growth and water parameters we recommend an Alkalinity level of between                     8 – 10dkh to be always maintained.

PLEASE HANDLE WITH CARE-once submersed the rock will harden and strengthen overtime

Made in South Africa.
