so because you disagree with my methods you wont answer my question? I really just want some help
I answer your question;
*That depends on is uptake and you should be using a test kit, which will show you its demands, so you know how much to dose.
*And the reason behind that is what may I ask ? Sr does about zippo for corals, if that is your reason.
Sr is not a require sup for corals, it is a substitute ion the just takes the place of C a++ because it is there. Naturally occurring aragonite precip' out of seawater will also pull in Sr, because it is there and fits into the lattice.
I asked you for your reason, a simple question, so it is you not answering questions.
Quite being so snippy with your replies ! People are just trying to help and are not mid readers.
