hey guys. so im looking to go mostly SPS with a few LPS. on my RSM 130D 34gallon, i used to use ME CORAL cal, alk, and magnesium. I have the eshopps 2 part doser, and dosed cal and alk throughout the day. i maniually added magnesium. i havent started dosing yet since i started the new 50g. i was thinking of going back to the 'OG' ESV 2 part for dosing cal and alk. is this the 'gold standard' for dosers still? its a lot cheaper to use ESV, but if theres other brands that you guys recommend, fee free to chime in.
