I failed Kobayashi Maru
What is the difference between Purple up and Kent Marine Liquid Calcium, and should I be using both? I know they're necessary for the lrs, but are they both the same thing?
Before you even think about adding calcium, what is the calcium level in your tank now?
PurpleUp is a total waste of money. It contains a weak solution of calcium chloride and ground up aragonite. The Kent Liquid is fine for raising your calcium level...if needed. An even cheaper alternative is Kent TurboCalcium. Mix 2 cups of Kent TurboCalcium in a gal of RO water and you have a gallon of Kent Liquid Calcium. :)
