I've been noticing that the sphagnum moss for my four fly traps and nepenthes is turning green, like algae or mold is growing. I have a picture of what the media looks like. Is it normal for this to happen or would it harm my CPs? :?

It shouldn't be a problem but how are you growing the plant? Indoors or outdoors? What's the airflow like around the plant?

My plants r grown indoors. And the air flow should be fine since they r on my bay window facing east in my living room. The front door to my living room is regularly opened and the AC and ceiling fan is now often in use because the weather is getting hotter.

A dark green color usually means algae is growing.
It can overwhelm and smother small plants.
I deal with it by burying it under a thin layer of silica sand top-dressing.
A light green color with fluffy new growth points means that you have Sphagnum Moss coming to life from dormant spores.

Where do I get the silica sand top-dressing? And what brand do you recommend? My VFTs are small but have been growing great with no problems, I just hope I'm not too late saving them because Idk how much algae is growing under.

You can use Marble or Granite aquarium gravel from your local pet shop.
You can also use pool filter sand from your big box building supply store or pool/spa store.
Pool filter sand usually is sold in a 25 or 50 pound bag bag for $20 or less.
I usually rinse it first.
Then I sprinkle on a few drops of vinegar.
If the vinegar starts bubbling, rinse it again and try the vinegar test again.
