using small amount of IO. RC that has been left in bucket for 2 weeks?

[Devaji]

long story short, I had about 2 gallons of left over instant ocean RC from my last WC.
new tank so i was not running the skimmer, now I want to start it again.

I left the RC in a bucket with out flow or heat in the basement about 50F temp.
think I could use one gallon just to make sure I have enough volume when I turn on the skimmer?

tang is 80 gallon RS 300XL
only life is gorgs & macors a few snails.

I know the general rule with IO RC is use it up not to store it but thinking that a small amount might be OK?

its takes a long time to mix RC so making fresh it doable but not ideal for a small batch.

thoughts.

I wouldn't hesitate to use it. Especially such a small amount comparative to the total water volume.

that was my thoughts too. just want to get other reefers feedback.

I leave a brute full of mixed IO/RC for a week - 10 days every time I mix a batch in my basement. I just circulate it for a few minutes before I use it. Never been a problem.

I have 30 gallons of pre mixed salt water I keep in my basement for weeks sometimes. I heat it before doing a water change, never been a problem

with instant ocean reef crystals?
different salt mixes and stores differently.

No just Instant Ocean, but I don't see why it would matter.

 

[exnisstech]

To clarify I'm use a 50/50 mix of IO & RC

No just Instant Ocean, but I don't see why it would matter.

I believe RC has more organics that could mess with the chemistry, at least that is what I remember .
with such a small amount it prob. would not matter. but it might,

I routinely have a 32 gallon brute trash can full of rc! I just check salinity before i use but i also leave a small powerhead in the can along woth a heater. The longest i used it was over the course of 2 months and didnt have any issues. Granted that was doing 2 gallon water changes though

lol I make saltwater and store it for months with no issues.

for sure but some store better than others. some need flow and heat others do not.
so hence the question.

I remember BRS doing a vid.. on it. I guess I should re- watch it.

It’s kind of a given that at a minimum you should have a heater in it. Flow just allows it to heat more efficiently.

I use RC. I mix 50g per time heater and flow, so that's different. I check sg before I use it. It lasts me about 2 months. No issues.
