i'm currently using seachem reef advantace calcium, in the powder form. I was wondering if I could mix the 500 gram bottle into a jug of ro/di water and dose it like a two part? versus mixing in water a little at a time. will it loose it's strength being mixed up and sitting in a jug?

also, is it safe to use at the same time with my alk supplement. i'm currently using the alkalinity part of randy's two part.( I live deep in the south. so I have never been able to find a suitable de-icer to make the calcium part) the instructions on the bottle say not to use it the same day as any alk suppements. what adverse affect would this have? sorry if i'm rambling.
