5" of soil would be off the hook!
3/4" to 1" of soil is more than enough for an 18 month go at it!
With @ least a 1.25" of cap.
I recommend a tight cap like a sand of some sort.
What do you mean 18month go of it, I am curious? I do not plan on changing out the dirt after 18mo?
Edit after re-reading thread.
OP: What are you using for filters and/or powerheads?
I have a 210gph powerhead on a dual sponge filter, a 250gph powerhead on one end and a wave pump I put in there to disturb the surface. I have also added and subtracted bubblers to see if it makes a difference * it doesn't except it cleared up the cloudyness (bacterial bloom) i had or it was just a coincidence that it was at the end of the cycle im not for sure.
Add Malaysian trumpet snails.
I added some, but maybe not enough. I was hoping to add a seed amount of MTS and they would expand and strike a balance in population.
Given how he types it's pretty clear it's 1.5 inches of soil and 1.1 inch of cap. A total of 2.6 inches of substrate and perfectly within bounds of reasonable. 5 inches of dirt is just silly. No one does that.
Dirt Tank turned anaerobic:
1.1in Blasting sand
1.5 = 1 + one half of an inch or 3.81 cm of soil
1.1 = 1 + one Tenth of an inch or 2.74 cm of Blasting sand
So I was guessing alittle more than an inch of blasting sand.
this is a 20 gallon long aquarium with standard dimensions being 30.5 inches long by 12.5 inches wide by 12.5 inches tall.
I have no CO2, I have a fluval 3.0 plant with custom curve.
All dirt tanks will have anerobic conditions in areas with no plants. It's pretty normal. It's why it is suggested only to put soil where you are going to plant.
What plants are you having trouble with and how long did you leave them undisturbed?
I planted spike dwarf hair grass, elodea 2 types, jungle vallisteria, Myriophyllum, Bacopa Caroliniana, and Potamogeton sp. Only the Val has really rooted and expanded all others either rot and float or just stay the same or get slightly smaller.
The Bacopa rotted after 2 weeks, planted little after 1 mo being setup. Myriophylum is growing very slow, jungle val is... well jungle val and growing and filling in quite well. Elodea both types have above substrate roots that do no survive and has not produced roots below surface of substrate.
Dwarf hair grass has receeded in size of clumps and doesnt appear to be doing anything. though I was told this might take a while. Subwasssertang has disappeared, water lettuce has turned miniature, azolla has thinned to small sparse plants. All plants (except floaters) were planted at approximately the same time around 1 month post setup.
The only thing that has done well is the Ceratophyllum.
