50gallon Reef Crystals in 50gallon RODI

[animalkingdom]

I'm going to start mixing saltwater in bulk to aid in consistency from batch to batch. I am wondering if I mix a 50 gallon bag of reef crystals salt with 50 gallon rodi will it be at a good specific gravity? (1.025-1.026) I think it would mix up a bit low. Does anyone know the right amount of rodi for a 50 gallon bag of reef crystals? The plan is to mark that level in a 55 gallon trash can and just fill to that level, dump a bag of salt and mix.
Thanks

I would start with less water first . . put the entire bag and test. If its higher than your target add more water until you reach the specific gravity you are targeting.

Hope that helps.

I believe it would mix up to about 1.022-1.023 going by the mix amount on the bag. I would just start with 45 gallons or something, then add a little more water to dilute if needed. It will probably take a few tries to find the perfect amount of water to use.

I've been doing some searching and noticed Copps in his tank of the month article mentioned using 50gal with 50gal bag spot on. Found that interesting.

I know its not 50 gal to one bag. I have a 60 gal mixing cube (with a 100 gal rodi cube above it with a gravity drain) as my mixing station. I've a line drawn on my mixing cube showing how far I have to draw it down to sot that when re-filled with RO/DI and 1 50 gal bag of reef crystals it mixes to exactly 35ppt. That line is not at the 10 gal line.. its higher.

So experiment and draw yourself a line :)

sound advice there thanks!

45 g might be a reasonable guess. I agree that some experimentation should help.
