Red Sea Blue Bucket - measurement by volume (cups per gallon)?

[samnaz]

Does anyone use this salt and know the exact amount of cups per gallon?

I don't have a scale, and pounds per gallon is the only amount listed on the bucket. (I've also read that measuring by volume is more accurate than measuring weight, because weight changes when salt absorbs moisture, or something along those lines...)

I know 1/2 cup per gallon is the amount recommended for some other brands, but I thought I'd ask here first before mixing and testing salinity a bunch of times to get it right.

I have the RSCP salt and I go with the 1/2 cup per gallon suggestion and get 1.025 every time

I'm fairly confident that meant "+1" (thumbs up) to the previous post and agreeing with 1/2 cup per gallon.

I used to use Red Sea (regular) and always also just did 1/2 cup per gallon (before checking salinity).
*same with other salts I've used

What salt are you using now? Any special reason for switching?

Red Sea is fairly expensive for me while Fritz RPM has similar parameters and is relatively cheap.
...beyond that, if you're new and trying to decide which salt to use,,, that's a very subjective topic and you could easily find MANY threads discussing that on this site.

1/2 a cup per gallon, like others have said. You get 1.025 salinity.

Thanks, guys. I kept reefs in the late 80’s and 90’s. A lot has changed since then
