Hey guys I'm currently creating my Aro DI water I was wondering I have a 33 gallon brute can and I have a 75 gallon display tank with a 30 gallon sump I'm going to have to fill my 33 gallon brute up about three times so how much salt should I mix in with each 33 gallon brute ?
Salt mix! Urgent !

The directions on a bucket of Instant Ocean says (1/2 cup of salt for each gallon of water)
Instant Ocean Sea Salt Mixing Instructions:
NEVER mix salt in an aquarium containing animals. In new aquariums, transfer animals to the aquariumonly after salt is completely mixed, the solution aerated, and specific gravity adjusted correctly. Water Changes:
We recommend monitoring your water parameters (nitrates, phosphates, alkalinity, and pH) and performing 25% water changes as necessary. To prepare small quantities of Instant Ocean salt for use in your water changes, use 1/2 cup of Instant Ocean salt for each U.S. gallon of water. Mix as directed above.
Instant Ocean Sea Salt Mixing Instructions:
- Mix Instant Ocean salt with reverse osmosis or distilled water for optimal results. Tap water can be used, but it must be treated with dechlorinator prior to use.
- Stir vigorously to thoroughly mix salt and water. Although the solution can be used immediately, we suggest that you aerate the water with an air pump to adequately oxygenate the water prior to use.
- Adjust salinity with an accurate hydrometer such as the SeaTest® Hydrometer full range specific gravity meter. Recommended specific gravity range: 1.020 to 1.023 at 75°F. If specific gravity is too low, add more Instant Ocean salt. If too high, add more dechlorinated water.
- Tightly reseal bag to keep moisture out. Be sure to store remaining Instant Ocean salt in a cool, dry place.

I don't use measured volumes of salt mix.
I highly recommend adding salt in portions and letting it dissolve before adding more using a calibrated refractometer to check the salinity as you go.
The high concentration of dissolving salt in the bottom of the mixing container could result in precipitation of minerals like Calcium Carbonate.
Suggest you heat the water to near tank temperature as you get close to the desired salinity as cold water could affect the refractometer readings slightly.

1) make sure to calibrate the refractometer
2) drop in heaters and powerheads
3) add salt per manufacturer instructions
4) test salinity and adjust accordingly
5) add to tank when completely dissolved, and clear

The cups for gallon is just a starting point, you should never go by that alone and always use a refractometer to make the final adjustments. If anything add slightlly less to start with and add the remaining once it has been mixing for a few minutes to an hour and has stabilized.
Add the salt slowly, don't just dump it in or you run the risk of the salt flashing and causing cloudiness and precipitate.
