Caribsea Super natural

[Bronxreef]

I am about to start a new 40g nano reef, I purchased 2 bags of 10lb Caribsea Super Natural sand to mix with 30lb of live sand but I just noticed it says neutral PH will this be a problem if I mix both? I was trying to save a few bucks lol

Idk that particular brand, but a lot of sands make claims about buffering ph. It's a thing that aragonite sands do, that quartzy/silicate sand don't. So play sand from Home Depot won't buffer ph, or like sand from your backyard.
Without getting into the chemistry, it's not going to hurt anything.
