Cycling Question

[DaReefer16]

I have a 90 gallon tank that I'm setting up. My question is
can I add RO water to tank and then add salt to mix?
my water is in 4 different trash cans and I don't want to mix them Individually

No, you need to mix it in buckets/trash cans then add to the tank

That's what I done to all my tank. I never seem any ill effect from doing that

And you should see his tank....... AMAZING!!!

if you are starting with dry rock and... yea, that’s fine.

If there is no livestock, which it sounds like this is the case, I definitely don’t see any apparent negative effect. Dont recommend it when the tank is up and running with other livestock, such a rapid salinity change can create problems.

I ran my RO directly into my tank for 3 days and then added salt.

 

[DaReefer16]

So the tank has dry rocks and dry sand in it no livestock.
should I add the salt to the sump return area or should I mix a 5-gallon buck of high salinity? and add it to the return area of the sump, let the return pump it to the DT?

I would pre soak those dry rocks in rodi water. Most likely there is die off. You’ll see the water get a yellow hue after a few days. Better than your display tank water turning yellow.

Agree. I’ve seen this happen in a friends tank.
