ro/di

[bigfoot]

if you start a tank on 100% ro/di what do you use to get the parmeters right is a calcium reactor good enough or is there some other chemical that you got to put in it beside salt cal strotium magnesium

If you start with a good quality salt mix like the Crystal Sea BioAssay formula and ro/di your parameters should be acceptable but any tank needs time to break in and cycle.
