as the title suggests, has anyone ever done this? or is it even possible?

From what I'm gathering from Walstad is that the NPT is ideal for low to med light setups. This allows the soil to produce Co2 at a rate the plants can utilize well.

Once one starts putting what would be considered high light to a tank and injecting Co2, essentially speeding up nature, the plants deplete the soil rather quickly. I think I read along the lines that algea can be a huge issue with high tech NPT as well.

Can someone else chime in?

I have dirt in all but two of my tanks (we have 20 or so tanks). All the way from no tech to high tech. Dirt grows nice plants.

more or less the info I was looking for. I don't see why it wouldn't be doable.

i am actually in the process of doing this exact set up.

OCMG soil, mineralized via AaronT's how to, capped wth flourite original

not quite high light, but a good deal more then low tech requires and CO2.

I'm going to do 2x54 2 hours of 4x54 8-9hours a day, mgoc injecting co2. gonna start EI dosing. we'll see how this turns out

I use dirt in all my tanks. In low tech tanks, it provides pretty much all the parameters needed. In a high tech tank it provides a safety net. Having a rich substrate won't take the place of dosing the water column and the better dosed the water column is the longer your substrate will remain rich, but having a rich substrate does provide some leeway if you get busy or go on vacation and such.

i started the mineralization 3 days ago.

i finished the wet/dry cycle today on my first batch. i have another soaking. and will most likely have another 2 to go

that looks great ! ,chadramsey..
any updates ?

Hello!

Here are some urgly telephone photoes of my tanks (240 L "community", 100 L "endler+platy+shrimp+catfish", 50 L "formosa+shrimp").
Age of all tanks - 4-5 ears without restarting.

All - on natural substrates below sand. All substrates are different - one is "composite" (mix of ingridients), one is soil for palms, one - based on pure biohumus (after two-week keeping underwater before placement for fermentation).
Result everywhere almost the same - good and long-term plant growth, no problems with algae and substrate quality.
Light - compact lamps 840 (in 50 L. 840+860), 0.7-0.9 watt per litre, had tried CO2 for about two years, but objectively see no reason in it and not using it any more.

Also I have some small tanks, one I like wery much:




and more



based on sand+biohumus.
