New to TRT setting up my 40g FOWLR

Hello all!! New here to TRT. I've made the plunge into the SW world. I currently have a 120g FW setup that's been running for a few years now and is doing great! I have always wanted salt but recently just started getting everything together.



What I have.

40gal breeder that was a FW setup years ago.

Sunsun 404B canister filter.

2 Marineland Maxi-Jet 600 power heads.

Instant Ocean mix for 50gal

40lbs Natures Ocean live sand

BRS 4 stage RO/DI filter

32 gal brute Rubbermaid trashcan



What I'll be getting in the next week or so

Refractometer

Lighting (not sure which yet)

Live rock

After tank cycles I'll be getting a HOB protein skimmer



As of right now for stocking I'm looking at:

O. Clown (2)

Green clown goby

And eventually a clean up crew



This will be a simple FOWLR tank until I can go bigger. My stocking may change but I think I'll be staying with the O. Clowns. and maybe some anonomies.



Now I have my RO/DI water in my brute trashcan, although I can't make enough at one time to fill my tank. (Until I get another can) Can I fill my tank with RO/DI water, get the canister filter going and then add the salt? Or would it be best to mix in the 30 gals in the trashcan and then add to my tank and then make another batch while I have the power heads circulate the water in the tank? Any other suggestions are appreciated as well. Thanks!!
