Hello,
No I am using Oceanic sea salt. I use to use the
IO kind though. I am planning on keeping the easiest corals out there as I am limited on just a coralife
T5 lighting source. Now are you saying when I do a water change and my replacement calcium is 350
ppm that I should be adding calcium into my bucket to catch it up to lets says 450
ppm thats already in the tank? should I do this before adding it back into the tank. what about top off water? can you get liquid magnesium? thanks........Shaun
