Live Sand Changing Color?

Greetings all,
New to the hobby!
75 Gallon tank
Halide Lighting
Heater
Cascade 1200 Filter
About 30 lbs live Rock
About 10 lbs White base rock and coral
About 20 lbs live Rock uncurred Rock (added about same time)
Substrate (Live Sand)
Five Snails
Five Hermit Crabs
PH 80-82
Salinity between 1.024 and 1.025
Amonia 0 ppm
Nitrate 0 ppm
I'm on my 21st day in cycle and the Live sand which was originally white is now slowly turning brown in addition to the white base rock.
Is this natural?

Yes, It is fine. the brown is diatoms...every new tank goes through it. It will go away on its own.
 
happened to me like he said it happens to everyone! it took mine about 2 weeks to clear up... but in my dads tank it took about 11 weeks...

You can also get a phosphate remover. Diatoms feed off silica. This will speed up the process. Did you use tap water to fill your tank? What are your phosphates at?

Agreed with above.
Make sure your flow is adequate as well.
Those things come and go. Instead of Physoban you could try using mangroves and algea. I actually saw somebody who aquascapes with the green algea. Looked pretty good too.

This is all normal....
you will go through a diatom stage...(brown stuff)
a hair algae stage.....
a cynobacteria stage
and probably a few other things that are annoying but all are normal and everyone goes through them

Yeah, usually bad diatom blooms occur when you initially fill with tap water. Water Companies add silica to the water to help coat the pipes, so you get bad diatoms with plenty of nutrients to encourage their growth. You may want to consider removing phosphates/silica. Theres like 3 major brands that make it, one is called Phosban, one is Phosguard and the other Phosphate Sponge. It's just a fine crushed media that you pour into a separate mesh filter bag and drop in your filter for <2 days. Then you dump it out refill it and leave it in for about a week. (For Phosphate Sponge anyway). The first charge removes phosphates, the second removes silica. Your diatoms may hang around for a while so this will really speed things up. You can siphon some out if you can but they'll keep coming back for a while.

Going to add a few more to the CUC team tommorrow...I thought about that.
==>Beefing up your CUC is always good but they DONT eat diatoms, so they wont help that at all. And with the diatoms using up nutrients there probably isn't any other algae growing etc.. Make sure your CUC have stuff to eat in there. If its a new tank it may not have much of anything in there but diatoms. You may want to wait a few more weeks. FYI.

This is very true, mine went through all 3 stages, Ditoms- real bad, Hair Algae- not bad at all, then Cyano (Red Slime)- Moderate.
After that you'll just have your basic algae here and there but will be good. Don't freak out at what your tank looks like right now (trust me we all have), it'll get way better. Just do your routine cleaning & WC's still and you'll be good.

Greetings again! Thanks for all of the information. Yesterday I added 6 Turbo snails and 10 hermit crabs. The snails went right to work...amazing! This morning there is a big difference in the appearance of Ditoms.
