Okay.. so I read some treads where people had successfully used topsoil as a substrate for planted tanks and the have done really good. So I went to homedepot today and picked up some Poting soil not even thinking about the difference. I got home, put the soil into my 10g and pored water onto a plate as not to disturb the soil.... Well, after I took the plate out and stepped back to look at what had happened, I noticed all the soil floating on top of the water. I could see light through the water under the floating island of soil.. I had to leave it to go eat at a friends house so maybe some of it will be sunk when i get back, but im thinking im going to have to wash the tank and get some new "TOPSOIL".

Has anyone here used topsoil or even poting soil?
 
The only problem I have read about using topsoil as a substrate is occasional ammonia spikes due to ferts in the soil and organic material breaking down. I imagine this might not cause as much as a problem for certain inverts, but Im planning on putting some female bettas in here.
 
So im no substrate expert, but i think somthings wrong here... :flamed:

Like I said you need to put gravel or sand over it.

Inverts are way more sensitive to ammonia than fish and I never had any issues with mine. I would keep an eye on the parameters at first but it really should not be an issue.

levitating soil!!! lol.

like Ashley said, you need to cap the soil with some other substrate - sand or gravel. i personally would go with sand.

Well... it is "top soil" right?? :D

but yea i will deff get some sand tomorow. was hoping I could just use the soil for a more natural look, but guess thats not gonna happen!
 
Simple fix. Put the light on the bottom and plants upside down in the substrate. You could have an upside down tank.
