View Full Version : Best salt mix for storing saltwater?

09/08/2017, 07:01 AM
Does Genesis have any recommendations in regards to which salt mix to use for use with the Genesis AWC? I am planning on doing small water changes daily and wanted to know which salt mix would be best when the saltwater is being stored for 2-3 weeks at a time. At the moment I was planning on using Red Sea Coral Pro salt but Red Sea states it should not be stored long term. Thanks!

Hi Tikosyn,

I think if you use a circulation pump in your mixing bin and have the bin open so that there is plenty of surface area exposed to air for adequate gas exchange, the 2-3 weeks' worth of supply of replacement water will be fine. I probably wouldn't let it sit without circulation for too long to prevent it from going stagnant, though.

I haven't heard that about Red Sea Coral Pro salt before. I'm going to go read up!

Hi Tikosyn,

Well, scratch everything I said above. Red Sea Coral Pros salt mix does indeed recommend that it shouldn't be mixed with a circulation pump more than four hours. They must have a good reason for stating that. And I don't think I'd leave big batches of it sitting around for a long period of time without some form of circulation.

Perhaps contacting their customer support line would yield a better explanation. I apologize for the inaccurate recommendation above! You learn something new every day.

I use cheap instant ocean salt mix (non reef blend) for my reef. I have 100 gallon mixing bin and use 35 gallons a week. I top it off once a week. My mix pump is programmed to come on every 3 hours and it runs for 15 minutes at a time. When I mix up new salt water, I hit a button and the pump will run for 1 hour to mix the salt. My new salt water never stagnates or smells. I keep my mixing tank covered at all times. I will note that I do have a large system with about 700 gallons of total volume.

I've used Instant Ocean and Reef Crystals in the past. Reef Crystals leaves a brown residue in the mixing container and Instant Ocean does not. Regular Tropic Marin doesn't leave the residue either.
