So I mixed a brute trash can of saltwater with a power head from my tank thats 36 out of 42 days fallow (was a 2 am tank maintenance brain fart) luckily I did not use the salt water at all and it’s still all in the can. Can I use the salt in 6 days when the display tank is 42 days fallow or does it need to sit for another 42 days now?
