Is the rock gonna hurt my tank?

[TangsRLife]

I have a 125 gal (around 140 gal in total water volume) and have around 50 lbs of live rock already in. I purchased 40lbs of some great looking live rock from ARC (Atlantic reef conservation) who aquaculture their rock for a few years and sells it. I've been curing it for a month and a half even though it passed the smell test but I was wondering if I can add it all at once and expect little to no impact on my tank. It's cycled already so I'm assuming it should cause anything harmful to my tank?

Test your water parameters to make sure they have stabilised. If they are still rising I would hold of but if they have leveled off or started coming down then you should be fine.

i cured 25pounds of dry rock and added it all at once in my system but i also added my tank water while i was curing to the bac would be the same
