Questions about starting a new larger tank

moving directly to the 46g and using safestart

What SG is the puffer at now?

You will need a HOB filter until the SG is up to 1.018 & then you can start to add LR, powerheads & a skimmer. I wouldn't remove the filter until you have at least 1lb/g of LR. Goal is 1.5-2lb/g. Don't worry, it's a slow change over & we'll talk ya through it! You also don't really have to use a sump.

This is exactly how I got hooked on SW!

He's in freshwater right now. I thought it would be easier on him to just stay FW since he was in that at the LFS. Anyhow I have a filter already so would you recommend just starting the 46 gal out as freshwater and then increasing salinity by 0.002 weekly or start out with salinity?

If you have the money for a suitable amount of live rock set it up as a marine tank and drip acclimate him straight up, it will save you tons of work long term
