Salt Water Mixing Stations Let's See Them

digitalchrisg said:
Just remember to take the temperature into account when you are mixing the salt. I do the samething with not heating the water and doing a slow drip in with the changes, but have already calibrated the amount of salt to put in to water and just repeat.

Is there a formula or table that shows the relationship between temperature and salinity?

I grabbed this from some other forum, so I have no idea if it is accurate or not. I am sure you can search around though for it.

It is probably more important to figure out what the right amount is for your containers and then just be consistant with it. I rarely check the change tank because I know how much should be in there per the qty of water. I check the main tank afterwards to make sure nothing got screwed up, but so far it has been working great.
 
Is there a downfall to using tanks to hold and mix water? Thats how I do it, but it seems like this is taboo at least in this thread?

Tanks are great. But Brute cans are cheaper per gallon and have a smaller footprint. Plus, the tanks can be used for more important stuff, like frag tanks, grow out systems, sumps, etc.

OK, probably a really stupid question, but aren't most refractometers supposed to take the water temperature into consideration? If so wouldn't that mean that you would just mix to whatever salinity you are wanting rather than trying to mix to a different salinity based upon the water temperature?
 
I would keep your mixing station covered to minimize salinity changes. Right now I'm still making NSW in a bucket, and if I leave it uncovered while circulating and heating it for more than a day or so, there's a significant amount of evaporation. The fact that the water is heated, it's winter, and it's in my basement probably doesn't help any. :)
 
I am fixing to make a new system, but I never hard plumbed my barrels together because of the slime buildup and would take them out so I could clean them. Anybody else seeing this or you don't worry about it?
 
I plan to have a 2 Brute setup with a pump used to transfer water and mix the SW similar to a few of the posts. My question is how to plumb the SW pipes to get a good mixing inside the SW container. For the pipe that goes in near the top of the can, how should it be plumbed on the inside of the can? A pipe down to near the bottom? Just a 45 on the inside pointed at the side a little?

I don't get slime with RO/DI water. But I also don't plumb them together and do take them out for routine cleaning.

Yes that was my concern was that if I plumb them together that it would make it hard to clean, but it actual the saltwater mix that gets a little ugly looking and not the RO water barrel. Anybody else seeing this?

Instant Ocean Reef Crystals leaves a brown residue in the Brute can, this does need to be cleaned. It doesn't seem "slimy" to me though.
