salty water used for two part?

[kinerson]

My RODI setup is done in such a way that the fresh RODI water goes directly into a large rubbermaid container that I use to mix up my salt water with. After I do a water change and drain 95% of the container it then fills back up with RODI. There is a slight amount of salt in this water before I mix in my salt mix for my next water change. My question is this...

Can I use this slightly salty water for the two part recipe? Or do I need to create another holding container so that I have 100% fresh water?

Space will be an issue if I have to add another container otherwise I would of done it already.

Thanks,
Greg

A bit of salt water will cause some precipitation in each part, so isn't optimal, but is not likely to be a big problem unless it is more than a few percent of the total water used.

O.K. good to know. Thanks very much Randy.

You're welcome.

Happy Reefing.
