Well since IE search turns up squat I will try to answer this without seeing the actual product.
Weekly additions to my new water ( 6gal week water change ) include 150ml of magnesium (with this batch of salt). I'm getting to the answer. I also dose trace elements. 5ml of kent marine essential elements and 5ml of kent marine coral-vite. I add all of this before salt as it can and does change salinity.
Coral vite's ingredients consist of the following.
Calcium
Iodine
Iron
Magnesium
Potassium
Strontium
Vitamin A
Ascorbic Acid
Thiamine (vitamin B-1)
pyridoxine (vitamin B-6)
Vitamin B-12
Essential elements ingredients consist of
Calcium
Iodine
Iron
Magnesium
Manganese
Molybdenum
Potassium
If coralvite had manganese and molybdenum I'd just dose that, I'm quite sure kent knows that also....thus the 2 products.
My main reason for coralvite is to replace strontium in very small amounts. I test it monthly to make sure i do not exceed 15ppm as its hazardous.
Now onto results. Since my camera sux you will have to take other peoples word for it that I have Incredible Polyp Extension and get Amazing Colors out of my corals. Is this the reason why? I doubt it solely lies on vitamins....... It could attribute to it. I feed my corals regularly and also blast them with light. My growth is Decent considering I use 14k bulbs but not out of this world.
