Pressure at 75PSI is good! — you can go as high as 85PSI (let me know if you’d like to know how to adjust that), but anything over 65-70PSI is going to make those RO membranes a lot happier!
If you used chlorinated water I would rinse with dechlorinated water, unless its "live" sand, you can actually spread it out on something clean and let it dry
Live sand quickly becomes unalived when we rinse in chlorinated water. I wouldn't put it in buckets outside, I'd put it in buckets inside with salt water just above the top of the sand in the bucket. It'll start to repopulate the sand with some bacteria. You can even drop a couple of drips of that ammonia you bought in the bucket to help bump up the bacteria count even more quicklier.
if its live you need to keep it wet, don't let it sit in sunlight and get overheated
You don't have to. Drain off as much as you can and then add fresh saltwater (or aged from your tank). The bacteria can and will live in lower salinity.
What Tim said, and if you are worried about any residuals, treat the tank with a conditioner like Prime by Seachem. It doesn't have to be that particular one, it's just the one that popped into my nugget first. It'll knock out any chloramine / chlorine from the tap. In such small amounts, I wouldn't be concerned about heavy metal / copper contamination, and any additional silicates will only aid your cycle by feeding diatoms. Just my 2¢
Much better answer than mine. I was going to say to use tweezers to get each grain and dry it off with a towel then blow dry it with a hair dryer or heat gun. Gets your sand nice and dry but it takes a long time
Nah, not th sand. Keep in mind, in your tank it just sits still.
