Cyano or coraline?

[boboyo]

2 month old tank with very very stable parameters. I spent 10h a week on maintenance in the beginning and already have 12 very happy fish.

I see some tiny tiny coraline spots on my LR but there’s this big one who I’m not sure if it’s coraline or cyano since it’s trapping air bubbles (or creating the bubbles?)
my hob filter is right on top of it as you can see in one of the pics so it could be air bubbles being trapped from the waterfall. It’s spreading very slowly but steadily.
not sure if the flow from the waterfall is considered high flow in the area but it doesn’t seem stagnant. I can’t find much info on coraline making air bubbles so I’m slightly worried it could be cyano.
Any insight on this is appreciated.

Hard to take good pics but the white spots on the purple are air bubbles

Then that won’t be coralline. Prob dinos. Siphon it out.

It is cyano or another velvet type algae. Remove it by sucking it up with turkey baster.

Wouldn’t cyano need nitrates? I’ve kept it stable under 6ppm for a month now.

 

[1guydude]

6ppm stable for a month isnt nitrate?

 

[1guydude]

>6ppm

I doubt it’s dinos since I have tons of pods. My hob filter is basically a refugium and I also have a production of pods which I add to the tank every week to make sure my mandarin is nice and fat.

You are right my friend. I was able to break the layer with the turkey baster. I’ll try to take off the sheet. Any way to eradicate it rather than managing it? Without chemicals preferably

Hit it with a turkey baster and if it blows off its cyano. Also if it grew quickly its cyano or algae. Coraline grows slowly so unless the tank has been running for a while its most likely not Coraline. I would just blow off all the rocks and forget about it.

Did u suck it up or blow it off. Just suck it up and remove fron the tank. Watch that area and try and keep it blown off around their.
You got this. Just a small patch.

You could try vibrant or microbacter clean. I am currently running clean and haven’t ran into any bacterial blooms at all....not a “chemical”, but I know there is stigma to the snake oil lol.

Carbon or charcol. Hths

First off I’d like to say thanks and I really love this forum

2- I sucked it out carefully with a turkey baster. Took a while and lots of water but I had water ready to refill it.

3- I have a charcoal bag under my cheato in the hob filter. I change it every 3 weeks but BRS says it’s pretty useless after 3 days.

4- I’m filling up my 125g gallon upgrade as we speak (today was leak test). Should I put the rocks with cyano aside before putting them in the new tank or will there be traces or spores of cyano pretty much everywhere?
