Is there any way to stop substrate going mouldy?

[HotdogKnight]

I'm using coco coir and it's very moist (I hate that word). I'm just wondering if there is any way to stop it growing mould - the white fluffy candy floss looking stuff. It hasn't yet, however pots that I water on my window sill get it sometimes around the edge. I'm hoping that maybe if my tort is active enough and moves the substrate it shouldn't let anything settle?

I rarely see any mold on my coco coir. My green house stuff was getting mold, so i run a fan on low to move the air a bit, and that has fixed it.

What I use is orchid bark with a layer of potting soil on top of it. I pour a little water into the corners and the orchid bark absorbs it but doesn't get moldy. Also the top layer of soil stays dry...So high humidity and dry substrate. Both on the plus sides!

That is fungus you are talking about, not mold. It will not grow on the coco coir alone. It needs a "food" source. Keep your coir free of leftover food and poop and there should be no fungus or mold issues.
