Product Description KH BoosterA specially developed product to increase carbonate hardness for use in marine and freshwater aquariums. Contains a select blend of different carbonate hardness boosters for fast and safe use in aquariums to ensure optimal nitrification and healthy coral growth.

Dosage: One level dosing spoon increases the carbonate hardness at: 20 liters by about 11 dH°40 liters by about 5.5 dH°80 liters by about 2.7 dH°100 liters by about 2. 2 dH°. Directions 1. Measure the appropriate amount of KH Booster for your aquarium size. 2. Dissolve measured in water. 3. Distribute dissolved solution evenly throughout aquarium. 4. Monitor and adjust level as needed.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
