So I'm just getting started with my tank. Still cycling but getting my additive supply stocked up. I plan on keeping SPS & LPS. I want stunning corals (who doesn't) but I really want to focus on dosing some chemails I have not used in the past to help achieve optimal results. I have a 15 gallon column tank. My light sourse is an AI Prime 16HD. I'll start with what I already have. B-ionic; Alkalinity, Calcium & Magnesium. I have Red Sea's AB+ and Ferrion by Brightwell (to help my Cheato stay healthy and a Manvrove.) I have the Red Sea Foundation test kit for the Major elements. I am going to buy an iron test kit as well but wondering if I should just buy the Red Sea Coral colors test kit (iodine, potassium & iron). I was looking into a few additional additives from Brightwell. Strontion/Strontium (I will buy a test kit) BoroChrom (is there an at home test kit for Boron?) Potassion/Potassium and lastly Koral Color (seems that will be a good addition with the Red Sea AB+). I wish I could just contact Brightwell directly, I love their products but is anyone out there familiar with any of these products? Are any of them unnecessary because one of the other products already has it? I don't want to over dose! Randy I would love to hear your expertise.
