I like Fritz RPM . Mix very fast like in 10 min and doing water change. The Parameter is good. It remind me of TRopic Marin Pro with fraction of the cost.
I honestly have no idea. My tank used to be a mixed reef and my few sps did well with the RCSP but was scared of the alk increasing without me testing.
So basically it's because I was lazy and cheap! Lol
True. Like with most things in this hobby whatever works for you is best. I've used TM, Red sea, kent marine, etc. and they all work. But since I've been following Sanjay since the days of Iwasaki 6700k bulbs and compact fluorescents I generally defer to his judgement. And someday soon I'll be buying a bunch of radions hahahaha.
