I have to agree. I posted a while ago about a hard green algae on my rocks that wouldn't scrape or brush off and was told by quite a few people it may be the beginning of coralline. At least 50% of the green is gone now and some spots are turning purple. Here are a couple pics of where it's starting to turn.
This is a pic from last week as the majority of green is going away and some is turning purple.
This is when I had a lot of green and some of it first started turning
Yes!That's the same green I have, you're saying that went away and is now purple?
Well that’s great news, thanks
No guarantees though. You have to remember R2R is filled with antidotal with a sprinkle of scientific evidence.
Like Salty Reefer said there are many different variables but there's a good chance it is. I actually just noticed a dozen or so spots on my back glass that I think are coralline too [emoji16]. Now if I can just get my nem outta hiding [emoji53]
Looks nice! How old is your tank?Some spots at small marker with yellow arrows. You can also see some light pinks starting on the back overflow.
Tank is about 4 months old. I’ve had absolutely no coralline algae growth before adding the ARC.
Nice, looks good
Yes! Looks good. Can't wait to get mine started once I move my tank at the end of next month...I introduced on January 22nd. I was wondering about the green but it has some hair to it now so I don't think mine is from the bottle.
Just noticed some purple/pink developing today though. I ordered another bottle as a precaution and arrives today or tomorrow but it looks to be taking hold. Lots of diatoms too.
do you test your calcium and alk? Or do you just blindly add the purple up?
