bottled came cracked and was leaking in the box. Calcium all over the bottle. I hate complaining because it's probably a small business but I lost half the bottle.

I just started my first reef aquarium a few months ago and noticed the other day that the calcium level in the water had dropped to 350 ppm. I measured the necessary amount of supplement according to the directions on the bottle and added it to the tank. Easy. I did another calcium tests a few minutes ago and the levels rose from 350 to 440 which is exactly what I wanted. Now that my calcium level is where I need it, I can just use this product to dose every week to keep the levels up. Highly recommend.
