coralline algae

pham411 is an unknown quantity at this point
coralline usually grows fast in an established tank. you just need something to jumpstart it. liverock, purple up works well. and keep you calc and alk up

Test both alk and calcium NOW. One does not work without the other.

You have to find out your parameter first. You can't fix it until you know what is broken.

I agree with testing Ca and alk. I also think that coralline takes time to develop and you should see it spread as your tank matures. I've heard (but not tried) that scraping some existing coralline off into the water column is a way to jump start it spreading. So if you have even a little bit of it you could give that a try.

i know that coralline algae turns white when it dies and i have large white patches on my rock could that have been dead algae?

Yes I think the white patches are probably dead coralline. If your alk is low your Ca may be high because they are inversely proportional. What kind of salt did you use?

to be perfectly honest with you D, coraline should be the furthest thing from your mind at this point in your set-up, maintaining a stable environment should be your ownly priority for awhile! learn about yes, id suggest not fixating and searching for ways to introduce it! besides chances are your going to have a carpeted mess on your hands with other forms before your coraline takes hold, even with manual means to introduce it!

I couldn't agree more with veriann and the statements in bold above. There's a lot of talk in the literature and on the forums about coraline algae and it's importance in a reef tank. So much so that people begin to put more importance on it than it's worth. Coraline algae is naturally found on LR and, even though it has died back on new LR, it will grow out again given time and correct conditions. YOU DON'T NEED PURPLE-UP to get it to grow. Save your money and buy the test kits you need. They are, Ph, Ammonia, Nitrite, Nitrate, Calcium, Alkalinity and Magnesium at the very least. These are the basic set and every reefer whether they have a ten gallon Nano or a gazillion gallon mega reef ought to own them (and use them). Get your water parameters correct, your cycle complete and let Mother Nature do her work. Coraline algae will come on it's own. The only benefit coraline has is it indicates healthy conditions and it's colorful in it's various color forms. That's it! Nothing more, nada!!!

Coraline algae needs Calcium present in the water at the proper level just like corals do. So if you are low on Calcium you are not providing ideal conditions. Can't test for Calcium? Can't provide ideal conditions! Alkalinity to high? Then two factors are possibly fighting each other. Testing for Magnesium, you might find your level well below natural sea water's 1250 ppm. This will force Calcium to precipitate out of solution lowering it and raising Alk levels. That's why you have to test for Magnesium. The three play off each other. My system is seven months old. I test weekly and maintain the following levels, Magnesium = 1400ppm, Calcium = 450 to 500ppm, Alkalinity = 4 to 5 meg/L. These are a good target to aim for. My coraline algae is beautiful, my corals are growing great.

If you want coraline algae to grow test properly or all the Purple-up in the world added to your tank will only give you purple water. When proper conditions are provided coraline algae will grow on it's own as dreams has stated.

Once again I have to state - The only thing that happens fast in a reef tank is disaster. Relax, test for the important things, let your system mature and one day you will notice purple coraline algae forming. Then when your system matures a bit more you will begin to see red coraline algae and other colors, too. Relax, enjoy the journey.

I believe that Reef Crystals has extra Ca. So if the Ca is high when you test your water you might want to use plain IO until it gets where it should be. Right now I don't recall you having anything that has a high Ca demand in your tank.
