how long do you mix fresh sw?

[benny z]

when doing a water change, how long do you let your fresh saltwater mix?

 

[jski711]

I mix a few hours and sometimes overnight.

 

[m and m]

I use to do it for roughly a hour, A few weeks ago i read it was best to do it for at least 24 hours to let all the chems truly de solve and deoxidize i believe they called it.

 

[benny z]

salt manufacturers almost always recommend mixing until the water reaches oxygen/carbon dioxide equilibrium.

since we have no way of measuring this, at least no easily available hobbyist measurement device, is it just a guess?

so, i'm just curious how long the average reefer premixes...

I use Brightwell salt and let mix at least 4 hours.

I start the day before the water change.
Fill the container with RO/DI water and heat it up to 75 degrees. Then I add salt and use a power head to aerate the whole batch and let it mix overnight.

The minimum for me is 4 hr. I normally let it mix for at least 12 hr. I use 5-gal buckets for my water changes. If I was mixing larger quantities in carboy or tub, 24 hr. would be my minimum. I'm also a firm believer in filing the container with RO/DI water and getting it circulating before adding the salt. I think it mixes better and faster if the water is moving at a good speed when the salt is added. And never add water to salt, always salt to water.

That's what I do. It looks like a whirlpool when I put the salt in and mixes much better imo.

I mix for 24 hours minimum and have a powerhead and heater in my SW vat running 24/7.

 

[btkrausen]

I mix for at least 6+ hours, and then heat up to temp before actually doing the water change. Never had a problem.

In an emergency as quick as you can get it mixed. Non-emergency at least 24hrs.

 

[ahvrivera]

24hrs min with a power head and heater.

 

[benny z]

i use a mag drive as a heater. dual purpose...mix + heat. haha!

i usually actually have to let it cool back down some before i use it after mixing w/ that thing.

 

[mizzoumed02]

Usually 8hrs with a heater. I've found thats what it normally takes till everything is completely dissolved and mixed up.

 

[FishLipz]

24 hrs with a powerhead, heater, and air stone.
