I've been using reef crystal now for about 8 years and been dosing 2 part. Do I really need the RC if dosing 2 part ???. In the near future I'm going to need larger tanks, in turn larger water changes. I'm trying to save money every where I can. If I would of used Instant Ocean in the last 8 year I might of saved around 400 dollars. What's your thoughts on this???. Theres a lot of us out here on a budget.
