sand before salt

you'll get salt sitting on the bottom that wont dissolve. I'd either mix the water first, or mist the salt in the water in another container.
 
well i suppose you could do that. You'll obviously end up w/a dust storm for a couple days, but should work.

Is it just plain dry sand (well now wet that its in your tank :) ) or was it live sand? If live sand, i dont recommend stirring it as you can kick up a spike of some sort....but then again, you're just starting the tank anyways, so i guess if it has to cycle its not gonna hurt much :)
 
it shouldn't matter at all since it's a new tank and has to cycle anyway. as long as you have a heater and circluation it should mix. as for the dust storm, that's probably going to happen no matter what on a new setup. just make sure the water temp is normal , (75-80ish) it will help dissolve the salt better than icey cold water.
 
I added silt (very fine, dust like sand), topped it with RO water and later added salt to the sump. The thing eventually dissolved. No ill effects as far as I can tell.
 
well when i set tanks up this is what i usually do.ill use i bag of live sand mix with reg arganite first add live rock,mix salt in five gal buckets with luke warm water.i then cup it in over the rocks till half the buckrt is in,then gently pour over rocks.i know little more time consuming but less cloud.(remember your dealing with saltwater,good thing happen for those who wait)
 
When I setup the new 180G with the 75G basement sump, I started with dry Aragonite, ran the RO/DI directly to the display and filled it up (3 days). I then turned on the return pump and added salt to the sump. It worked just fine.
 
I added ro/di water, filled tank and turned on the pumps. Brought water to temp and started adding salt. It mixed up in a day, checked levels. When I got my sand I added it, I set the bag on the bottom and kind of dumped it out not much of a sandstorm.

I may be wrong about this and I bet it matters how deep your sand bed is, but if you added say 4" of sand then filled with water, turned on pumps, do you think the water at the bottom of the sand is moving around? I would think that it would just sit there, but if my high school chemistry memory holds true isn't salt water heavier than pure water? So I guess it would displace in fresh water sitting in the sand not circulating.

get a rubbermaid Brute tub, wipe out, add ro/di water, add sand, add small maxijet pump, leave running for 12 hours, and you've got well-mixed water. Plus you have a tub you can use for ro/di storage. A Lowe's white polystyrene bucket from the paint department makes a good waterchange bucket for mixing small amounts of saltwater for your weekly change.
