Trying to get coraline algae

I've got them in my cannister filter, on powerheads etc. Their are so many it's unbelievable!! I never really knew what they were-thanks

 

Is this coraline algae?


BTW guys, how do you place your pics directly in this box verses the link attachments?

Thanks.

 

I wouldn't call it corraline. The purple stuff on your rock is, but not what is on your glass.
As far as images go. you have to upload the image to your photo gallery.
Down below the image is the hypertext or link to that picture. If you highlight that link then paste it into your text. It will appear in your message.

What would you call it then?

And, if they're both purple (rock & glass) why is it not coraline?

Just curious, tks.

ps: Thanks for the pic tips.

 

Started with some nice LR. Use Marc Weiss Reef Vital DNA 1 Capful per Day. Results are fantastic!

 

Here's an easy way to tell. Use a magnet cleaner (or a clean rag), and wipe the microalgaes from the glass. If the purple stuff comes off too, it was cyanobacteria. If it stays and can only be scraped off with your fingernail, it is coralline.

 

Very good answer. That is what I should have said
It looks like the stuff on your glass is easily wiped off. With Corraline you could wipe the algae cleaner over it many times with no results.

O boy...coraline is not easy to get off the glass...especially after you are out of town for a week and its everywhere..XD

 

Patience my friend, patience. I am barely getting the dang thing after 8 months.

 

Every LR I put in, coroline algae grow on it within 2 days. That's how good purple-up are...or I am doing something else right (which idk what ).
