San Pedro's Cactus fungus on sproutlings?

So I purchased 100 seeds from a vendor and planted them... Microwaved the soil... followed a video tutorial and I have some sprouting, however I just noticed that I see white fluffy fungus on the soil and some on the cactus. I put them into the contained on the 2nd of this month (4/2/15) so in about 2 more days they'll be a month old. I'm not sure what I can do to save these cactus as I want as many as possible to survive, I'll upload a picture in the morning. What do you think I should do?

Roots look a lot like mycelium for a few days after germination

I can't see the roots, also the soil color hasn't changed enough so I can notice.

Hopefully the other way around? 
It might be cobweb mold, or Botrytis (damping off). Pics would help. A simple remedy can often be to increase airflow, let the surface dry out more, spot application with a diluted h2o2.

Yes it was the other way around lol, it was late. So I guess start poking holes on the plastic so let the air vent? I'll take a picture once I find my camera.

Depending on what exactly is happening, a more urgent action might be needed. Damping off is terminal, and will potentially kill all in your pot. If it is a mould, the seedlings will suffer less than the mould if you fully remove any cover and let the surface dry out.

Looks to be cobweb mold. Give them more air, and optionally, spray down with diluted h2o2. Nothing too serious, the seedlings aren't in any great danger.

How do I give them more air? Just make holes on the plastic wrap that's on top? Or do I just open the seal a bit or how do I do this? Also H2o2 as in hydrogen peroxide? Also I'm really happy to hear it's not a great danger

Cobweb mold is best fought with hydrogen peroxide. Full strength. See how well it works.

Alright, I'll give it a go in a bit. How do I vent the air so it won't shock the cacti?

As in 100% h2o2, or as in 3% or 5% straight from the bottle?

Sorry, 3%. That's no dilution right out the bottle.

Do how much do I spray on them? Also do I just mist the whole container? Or should I only mist the spots that have the mold?

Just spray the whole container and as for how to spray it, just pour some in a spray bottle or I crew the spray top and put it the h202 bottle

You'll watch that shit melt before your eyes, repeat as necessary h202 turns into plain old water so don't be afraid to give it some

I would use a dropper then just drop some where the problems are.
