My Tank Thread
Thank youI've read a couple things about rscp that says it doesn't store well, but yours is the first I've read about rc, so that's good info to have. I was worried I was going to have to use regular io to be able to store it, and then dose for the differences.
There are some issues storing reef crystals. It has to do with the vitamins in it. They will likely degrade once dissolved in the water, and could be food to drive bacterial growth as well.
So if you think them useful, you probably should use the water shortly after making it.
I'd also recommend keeping RC aerated to prevent stagnation from potential bacteria, while ordinary IO (like I use) has no problem being stored for long periods unstirred.
FWIW, I don't see any benefit to RC over IO except a small amount of extra calcium, which, if needed, can simply be added to it or to the tank. In my case, I prefer the lower calcium since I use limewater (kalkwasser) which tends to increase calcium over time.
