Mold or fungus?

[Irishman]

Tank has been up and running for about 3-4 months and I’m noticing some growth outside of the water/tank. Looks fuzzy and white, so I think it’s mold. First time setting up the tank, 180 gal, since I moved to a different state. The tank I had set up in CO, 120 gal, didn’t have this issue. I don’t have much surface agitation and my wave makers aren’t pointing up. I live in OK and it’s definitely more humid here, could that be the problem?

I am following along. I have the same stuff growing around my tank.

First, mold is a type of fungus so they are the same thing basically. Having said that, I am pretty sure it is a mold that grows in the high humidity surrounding the tank. I have tried several things to get rid of it such as a fan, dehumidifier, and constantly wiping the tank down. No matter what I do it always comes back somewhere.

I also was thinking it had to do something with the screen too

That is weird.I have not seen mold growing so close to the aquarium before. I've seen it on the Dry wall behind the aquarium.Not right on the rim though like that.

Renewing this thread because I'm seeing similar growth around my sump.

Any info on this?

Looks like salt creep?

It's fuzzy and soft. Not salt creep. Definitely a mold.
