Which is better?

[tashi]

Can anyone tell me which is better for soft corals- strontium or iodine? Or do they play individual roles for the corals?

Is there any in the market that has 2-in one (Iodine and strontium) liquid?

If I want to get only one, which is the essential one I shd get?

Thanks in advance!

Iodine is for coloration. Strontium is for growth.

Need both. 1 bottle of each can last u few mths.....
