undissolved salt??

so i just mixed some water for a water change and i noticed small white specks floating at the top. i'm thinking it's undissolved salt but this has never happened before. could this mean the salt mix has gone bad? can i just scoop out the particles and still use the water? throw out the water? any experience with this?

 

How long have you been mixing it?

 

i mixed it about 4 hrs ago. the stuff is still there

 

What is the SG if the new water you made up? And what brand of salt did you use?

 

'' When mixing saltwater, the rule is to add the salt to the full volume of water. If you pour water onto a pile of salt, the water turns milky white and never clears. This is because a lot of salt and a little water create hyper-salinity. The water is much too salty, which often results in precipitation. The alkalinity and calcium levels are much too high, and this causes flakes or snow that won't dissolve. So remember, water first, then salt. Use a powerhead or large pump to mix the water and salt.

How to Change Water in Your Reef Aquarium by Marc Levenson - Reefkeeping.com

 

i did that. i added 2 cups of instant 2.5 cups of instant ocean to a 5 gallons of water. the sg is 1.024.
when i checked this morning there were less flakes. should i throw out this water or is it usable?

 

I have the same problem with instant ocean.
I did it twice and still the same problem

 

yeah i think i'm going to go with a diff brand next time.

 

do you think I can still use it???

if I change brands is it ok to add it to the established tank??

 

well the stuff floated to the top i scooped it out and used the rest. i didn't get any problems then. i'm having some problems now( about 3 days now) but they are due to a 7 hr power outage. it's been about about about 3 wks since i used the salt though.
i'm really new to this, but i don't think switching salt brands would be a problem.
many people might not respond to this thread b/c it's old, u cud start a new one and get some input from more experienced members.
