My 36 gallon is dirted with a thicker cap of Eco complete and plain gravel. I consider it to be mature since it has been established for over a year. It has only been fully filled for a couple months however. I had it in dry start for quite some time but the substrate was saturated. Plants have been doing fine an I've experienced minor hair algae. Lights put out low medium par after photo period is taken into account(short). Furthermore I haven't had inhabitants for more than a few weeks. I introduced an oto cleaning squad in hopes that it would be diatoms however they seem less than interested. What is causing these particles to settle on top of my substrate? I will note that the substate seems to be rich with microorganisms.

That is a lot of 'stuff'.

Are you dosing iron and phosphate fertilizers together? (I thought that was a white precipitate, though)

Fungus growth?

Can you vacuum it out? Or is it stuck to the substrate too well?

What kind of dirt did you use? I see a buildup of the same stuff in one of my nano dirted tanks.

Vacuuming is effective. It is a lighter material however it is embedded heavily in the cap layer of the substrate so a full removal would disrupt the aquarium too much.

I used mgocpm. I left it intact in the sense that I did no sifting.

Oh and no, I'm not dosing. The tank is extremely low tech. I've got a 2217 running on it so it has very good flow. I only do top offs when necessary

I do have a large rock in the tank but I can't imagine that if would be causing the issue

Could be the decomposition of the poultry litter or one of the other ingredients in mgocpm. If it's an eyesore, use a turkey baster to gently squirt it towards your filter intake.

Not a bad idea! You don't think it would affect inhabitants negatively do you?

They would have been affected already if there was a problem with the stuff since it's all over your substrate.

are there any areas sheltered by hardscape or a large-leafed plant in your tank? Just so you can try and determine whether it's something precipitating out of the water column, or if it's being produced by the substrate.

I have a current tank with MGOCPM, and a flourite sand cap, and I haven't seen anything like that, also had one for about a year with MGOCPM and black flourite cap, and didn't notice anything similar to what you have.

Any other noticeable traits? powdery, fibrous, goopy or anything?

I just reread your post, and noticed you said it's only been filled for a couple months. I wonder if it could be related to the extended dry-start, and only being recently filled?

There are very shaded areas of the tank however the mulm covers the entirety of the substrate. It can be seen within the cap layer. The tank has been fully filled for a couple months. When agitated with a jet water it forms orange clouds and briefly turns water orange until the 2217 clears it up again.

I might think it is one of the million different things which we never see until the conditions are just right. Fungus, bacteria, diatom or some other name?
A small patch of sand spread over a couple inches of the floor might give you a way to see if it is growing on the substrate of falling. I suspect it is something that will grow until whatever substance it uses is gone or changed in some way.
Like fairy rings in the yard, there are lots of these little things that come and we see them and then they are suddenly gone. I'm thinking it is something like what happens on driftwood so often.
