I'd agree with this, anything you use on your reef tank is like a drug and you have to slowly wean it off it otherwise it'll have withdrawals. Any change good or bad can have negative results and while RO water is better than tap it may not produce instant results, likely it will make things worse before it gets better. Stick with it though as the end result will be better.
