Hey Arc members I'm running a fowlr tank and I'm lookin for ways to get good coralline algae to grow any tips or advice?

I've bought a few different pieces from premier and other petstores that's covered in it but it don't look like its spreading Im also using purple up
 
could possibly also be that some "strains" of coralline grow faster. I don't know what the deal is, but mine grows fast, too fast. It will cover all the glass in my 8g in a month if I let it.

Your have corals?
 
Well, I am reading that coralline algae actually prefers moderate light, over intense light, which may be the reason why it was going crazy in my 8g under power compacts. Now I have LEDS over the tank

Also FOWLR systems tend to be loaded with excess nutrients, which is another reason why it may be harder to grow coralline
 
You don't need purple up or purple tech , all you need is to check your water and keep your alk , kh, and magnesium in optimum ranges.
Buy some rock with coralline on it and once a week take a knife and scrape off some tiny shavings in to a cup of tank water then dump the shavings in to high flow , another way is to put heavily covered rubble in front of return and circulation pumps it will blow spores around thus spreading it faster.
Coralline although a macro algae isn't an algae how we think of one. It uses magnesium and calcium from the water just like coral so it makes since for us reef keepers that keep our water clean and in optimal range to see more coralline algae growth.
Purple up adds trace elements potassium iron and fertilizer designed to stimulate calceris algaes such as coralline and halimeda and by boosting calcium and magnesium.
That sounds probably just like what you want , but actually the magnesium is not as usable by coral and coralline because its a different type than what we dose , its different so it doesn't bond to calcium in its bottle .
Dosing it just causes un needed spikes in these elements that jack up every day when you dose then fall again.
It has no longevity like regular dosing cal and mag.
That's stressful on the system and you can't really adjust the dose because it just all comes out together , your mag may be 1100 and cal 500 the swings are harder on the system , stability in a proper range is better , it just takes time.

Since its a fowlr I suppose it wont really matter thought the swings , but will be far more effective if doen with test kits and regular water changes and the addition of needed cal and mag .
The dkh should be 9-11 cal 420-460 mag 1250-1300 and coralline prefers 500nm blue light .
When I first started I wanted the same thing and used purple tech that's why I'm saying this , I already asked these questions and did the research.
I don't advise dosing anything without proper test kits though , another good seeding tool is some turbos or margaritas snails with coralline covered shells they spread it around good.
If you do these things it will grow , one day you will be saying ... Man this purple **** sure grows fast , as your scraping it off the glass or snapping a plug off a rock where it glued itself with coralline.
Good luck getting it going , maybe someone has some on there back wall that could give you a few scrapping , crush it in to as fine of pieces as possible an pour it in .
Good luck getting purple rocks fried.
 
Purple Up and other like products are a waste of money. If you have calcium, magnesium, and alkalinity within the proper ranges and some coralline in the tank it will eventually spread.

So these three would help even if I don't have any corals?
 
Yes, all shelled inverts and calcareous algae need calcium and many need magnesium.
 
She's right regarding purple up. It's just another one of those snake-oil additives. (There are so so many....it's hard to figure out what is actually useful.)

Unfortunately, the only thing that'll get you to where you want to be is:
1) Introduction of coralline into the tank (check!)
2) Studious attention to calcium/alk/mag
3) Patience

Ever since I started getting my tank ready for hard corals and a clam, I've had Coraline pop up every where.

I had a few bad experiences with clams. Due completely to my lack of knowledge. Once I learned that clams require (and consume) loads of calcium, I started upping the calcium. Once the calcium was at a stable 420/440, I felt that it was ready for another clam. What I did not expect was the massive Coraline growth.

Now, it all makes sense.
Back then, it was just one of the many mysteries that occurred.

I was told that purple up has calcium in but I guess they was wrong my next trip to the lps ima grab a bottle of calcium

My understanding is that it does. You're just paying a boat load for it.

Get a test kit for calc as well.
You'll have no idea how much to dose unless you know what you already have.

True that!!:thumbs:
 
Regarding Purple Up- here is a quote from Randy Holmes-Farley who is a very respected chemist and hobbyist-

"I do not recommend it for most people.

It is not a useful calcium and alkalinity supplement. The main ingredient, the fine aragonite, cannot dissolve in seawater and is wasted, as I showed here:

Calcium Carbonate as a Supplement

thanks for the article Stacy, I just read the first bit on break
