Hi all! I’ve had this spider plant for almost 10 years. I repotted a few months ago and it’s been doing fine but, then today I noticed this white stuff on top of the soil. I did a little research and it says it’s mold but harmless? Any thoughts would be helpful!

It’s harmless, but so annoying!!  
I try to keep my air circulating and give my plants as much natural sunlight as possible. I water with Arbors Fungicide and it kills mold immediately, but it inevitably grows back.

It’s mold but it’s harmless you can treat it though

the mold is harmless, but also a sign that your soil isn't drying out between waterings- that your soil is quite moist. you don't need to adjust the watering as long as the plant is still happy and healthy :)
