Fungus on Substrate
Since getting my new tank I decided to switch from gravel to a plantable substrate. Money being what I is I read up on the Walstadt method and decided to give it a try; substrate is John Innes compost with a fistful of bonemeal capped with JBL Sansibar. It's going well; the plants are flying, the fish seem to be doing well (pretty sure the Apistos have either eggs or fry (I saw fry last week, but haven't seen them since and the female is keeping herself hidden again).
The only problems I'm having are a white mould on one side of the substrate and bubbles from the substrate. The mould doesn't seem to bother the fish at all, they don't try to eat it or anything. I've tried breaking it up but it's back again just as much in a couple of hours. Trying to vacuum it off just took a load of Sansibar with it. The bubbles, again, don't bother the fish (I've seen one of my tetras catch a small bubble and spit it out again, the fish is fine) I'm wondering if this is dreaded anaerobic bacteria, or just CO2 from bacteria in the soil or something.
Here's a photo: it's covering more substrate now, but I think it might be breaking up

I'm not sure what it is but I have a new dirted tank as well and it went away after a month or so for me. As for the bubbles I've also seen them from my substrate but not sure what it is. Seems harmless so I haven't put much thought in it yet.20 gallon tall: empty

Well, it's good to know that other people are experiencing the same thing, that's calmed me down a bit. It became very noticeable about 2 weeks ago, so hopefully it'll burn itself out soon.

It could be.
Hmm... realizing this is not going to be a popular answer... have you considered a few malaysian trumpet snails? They'll aerate the bottom, get rid of the anaerobic builtup that's likely causing your bubbles and may well get rid of the fungus as well.
Downside. Once you get them they're there to stay.

Would they be likely to get out of hand if I have a pair of assassins in there?
I want to get some cories but I was worried about putting them in on the off chance that the mould is harmful.

it depends on what you mean by out of hand. if you are a light feeder then there wont be much food for them to eat, get rid of any algae too and they wont be very noticeable. on the other hand, if you get algae and over feed then they can have a big increase in population and be very noticeable. the assassins work but if i remember correctly they wont keep up with an out of had snail population growth.KING OF THE GOLD BARBS RAWR!!!!
I wonder if i plant one of my tiger barbs would the demon seed grow to a full tree?
gotta love them bunnies!
I.R.S.: We've got what it takes to take what you've got!

And the risk is always there. I'm a reasonably experienced fishkeeper, I know I feed a bit much because I want my bottom dwelling fish to get enough. So I got quite a few snails. Once you start with MTS you'll always have to keep them under control.
