salt mixing

[Reefie]

I don't think 7.5 lbs of salt will be thoroughly mixed with only 5 gallons of water. You would have quite a bit of undissolved salt sitting at the bottom of the bucket. And then comes the challenge of adding the right amount of RO/DI water to achieve the salinty. Might just be easier to have multiple 5 gallon buckets mixing your saltwater instead.

I once tried to make a brine with less water and the salt never cleared up. I wouldn't do it again.

Thank you so much! Now have to find rooms for my 32 gallons drum.

What do mean by this? ( it doesn't mix too well.)
How long do you let it mix before your water change? What salt are you using?

I use a 37gal. rectangular tank for mixing and let it sit over night with a powerhead and heater. Alway mix up clear.
I use reef crystal salt.

I see people mixing salt for only 10 minutes. Which powerhead are you using?

I use a AquaClear which I had from my freshwater days.
Last year I brought a bucket of redsea pro salt from a member which was rock hard and it mix up cloudy. I use a quick filter also from my freshwater days for the aquaclear powerhead and it clear up within about 15-20 min.

I could be wrong, but I think when you use salt that has hardened, some of the sodium bicarbonate turns into calcium carbonate, and that makes for the cloudy water, it will no longer dissolve. Check the KH of your new salt water.
Hopefully some of the keener chemists can elaborate
