Confused with making 500mL bottles of CSM+B using Wet's Calculator
I have a 60p tank and I want to use my old ADA 500mL bottles to make solutions of CSM+B. I am using Wet's Calculator but the English is confusing.
I input the following into the calculator:
I received the following output:
To reach your target of 0.5 Fe you will need to add 52.173 grams Plantex CSM+B to your 18gal aquarium to yield:
Dose these levels 2-4 times a week for EI. Classic EI depends on good CO2, good circulation, and regular water changes. Light past moderation is not so important.
Is that correct? 52 grams seems like a lot of powder to dissolve into a 500mL bottle. EI states that I need 0.5ppm of Fe but the calculator says I need to dose 5mL of this solution 3-4 a times a week? Thats 3-4 times what is recommended. Am I using this calculator correct?
