Review on 🔬 Kent Marine 00003 Kalkwasser Mix: The Ultimate Solution for Water Chemistry - 15.9-Ounce Jar by Tina Cruz

This product is excellent when used properly. However, you must read the instructions very carefully and DO NOT deviate from them. If you are new to reef aquariums, do a lot of research. It's not something you just throw in the aquarium and help the coral grow. This has very specific uses for certain species of coral, mollusc, and algae. I would also recommend Zoo Med's "small dropper". They cost $10-15 depending on the size. The small dripper is a plastic bucket with an adjustable drip valve. This is very important as the instructions state to add it to the aquarium at a rate of XX drops per minute or second. If you add it too quickly you will have clouds of calcium which can and will damage everything in your tank.
