Uncured saltwater

[reefgirl189]

We know that to add SW to your existing tank you must first cure it for a minimum of two days before the addititon (not talking about adding due to evaporation here) or water change.

What happens to those people who add live rock and then fill up the tank with freshly mixed SW? Will the LR essentially die?

Sorry guys just can't seem to find info on the repercussions of adding uncured SW. I can only find info on the fact that it should not be done.

Some people add it right after it's mixed or after only an hour or so. This water I find is fully mixed (visually speaking) but is not the same. I recently had to bring my salinity up after removing some sold rock (had simply added some topoff water to the tank to compensate for the volume of the rock as I had no sw on hand).

I noticed the foam fall flat in my skimmer once the newly mixed (for about an hour) sw mixed with the tank. Not sure what that means tho.

Interesting. I have never really heard of this or thought about it. I have used new water when setting up a Seahorse tank and used cured rock as well.

So what you're saying is your fish didn't sprout horns and/or wings and start flying away shooting lasers from their eyes, spearing innocent children and eating puppies?? Is the whole curing SW just a precaution for those with sensitive corals or fish?

Lol! Did nothing like that to the Seahorses...also set up a 25gal which is actually only a 20 if you get technical. I put 2 Bangaiis, a Clown and a Tailspot in and no problem, also a piece of liverock.

*snicker* hehe...

Well the reason I ask is because we are FINALLY getting our tank this weekend and it's a larger volumed one. We have 90 gal pre mixed saltwater just waiting but what if I need more? Am I going to kill anything or do any irrepairable damage if I put in some just-mixed SW into the tank while it's cycling?

I don't want to make any mistakes but I don't want to go buy three more of those rubbermaids brutes just for the sake of having the SW pre mixed. I don't have the room and I won't need that many after the tank is set up.

What did you get for a tank? Saw that you had been looking, must have missed the buy...

Everyone seems to love build threads and lots of pics! Get some up, let's see the beast....or did I miss it???.ugh...

I meant newly mixed sw seems to be different but I'm not sure how. Besides my skimmer I never noticed anything else.

If you're bringing rock home don't you have the water mixing and ready for it? If that water is just recently mixed I wouldn't worry about it if it's fully dosolved.

Should mention that I prefer to mix my water in advance. I find the salinity tends to change after it sits awhile, but could maybe just be me.
