If you haven't gotten any snails yet, get some now. (That's assuming your tank has cycled. I don't see any info on when you set up the tank, or ammonia/nitrite/nitrate levels.) A week after I got a handful of trochus snails, my diatoms were gone.

And no... it won't turn red, unfortunately.

I'm not sure what you were told to expect, but after only a week and a half (of doing anything) you're not going to see any difference in coralline growth.
The only thing that grows that quickly is stuff you DON'T want in your tank. LOL
When it comes to a successful SW experience, patience is definitely a requirement.

As for Purple-up, aquarists either love it or hate it.

Personally it's worked well for me.
I used Purple-up in 1 of the 4 SW tanks I have in the living room.
After 3 months that one tank had purple, pink, and green coralline completely covering the glass.

The other 3 tanks that didn't get dosed are only showing a few small spots of coralline on the glass.

As someone mentioned above, there really isn't anything in Purple-up that you can't get elsewhere.
Purple-up is just a combination of several things that you can get from PWC, and that aquarists commonly dose such as, calcium, strontium, iodine, etc.
Of course, even tho I'm terrible about taking my own advice, if you're going to dose anything you should have a test kit for it to make sure you don't overdose.

Two other things to consider...

The color and growth of coralline also seems to be proportionate to lighting.
The stronger the light the better.

Also, the more coralline you start with in your tank to "seed" it the better.
Purple-up doesn't have any coralline in it to get you started.
Did you start with cured LR that already had some nice colonies of coralline growing on it?
If not, go to you LFS and buy a few small pieces of rubble that have some nice, mature growth of red and purple on them already.

BTW, coralline does not start off brown. That sounds like a diatom bloom which is normal for a new tank.
With coralline, you'll notice tiny spots of dark green, pink, red, or purple on your glass (where it doesn't get regularly scraped clean) that will slowly get bigger and spread over time.

I thought my tank was the only one looking like that LR. Mine looks like that and from only PWC`s and no calcium or buffering supplements

If you're going to continue with the PurpleUp, even with the comments folks have made here, please at least go out and get a Calcium and Alkalininty test kit, and use them. If you get your tank chemistry out of whack, you'll be cussing yourself later on.

As Melosu58 noted, you *may* be able to get the calcium levels you need with just your normal water changes. Personally, I can't because my fresh salt water only mixes normally to about 360ppm Ca. BUT... the point is, I *know* what my Ca levels are in my tank and in my new fresh water I'm putting in. Without knowing that information, you can't really make a decision on what you need to do. Your new salt water may have 400ppm Ca in it to start with... in which case you don't need to add anything to get coralline algae to flourish.

Take a read of this...

http://www.advancedaquarist.com/issues/nov2002/chem.htm

It's my favorite article on the whole Ca/Alk issue. You should see how the two are interdependent and messing up one can mess up the other. Messing with Alk can have bad effects on pH. And after your pH starts swinging all over, you're going to see problems elsewhere.

I think one of the best pieces of advice I've gotten off this board so far is that if you're going to add supplements to your tank, then you should at least test for whatever it is you're adding. If you're not testing, you don't even know if you need the supplement to start with. Just because your LFS sells it, doesn't mean you need it!

Manny09 don't forget coralline needs light along w/ proper Ca and Alk levels to flourish. What type/wattage lights are you using and what size is your tank?

Should be more than enough. What K lighting is it? IME coralline grows best w/ actinics or higher K (10k-14k)lamps. It seems to favor a more blue light.
