Great info guys, thanks
Last question from my side. I have (if I remember correctly) 8 supplement:
* Calcium
* Magnesium
* Strontium
* Trace
* Iodine
* kH
* Liquid Phosphate Remover
* Kalk
My problem is that for my small system (planning on stocking corals heavily soon), I want to add (for example) 0.5ml of say iodine daily. But I find it difficult and a hassle to measure 0.5ml and easy to make a mistake. Now the question is, can I mix the above supplements with RO/DI water and store? The reason is simple; it is easier for me to measure out 1 tot glass of a solution than 0.5ml. So I could rather mix 10ml of Iodine with 630ml of RO/DI. Then adding 1 tot glass of the solution will effectively add 0.5ml of iodine. (Only using Iodine as an example.) This way my daily dosing is literally as easy as: "Add 1 tot glass of each of the bottles on that shelf, every day."
Can I do this with all the above supplements and if no, which ones?
