A young man gave me a loaf of glossostigma elatinoides he grew out of his homemade tank. I was impressed by the density of the loaf, evenmore when he showed me the tank where he grew it out from: a polystyren foam box with a nutritive soil, no CO2, no additional fertiliser, only plants (no pets). And all that are only lit by the tropical sun.
Plants grew and very little algea.

I am using CO2 injection, fertilisers, and i have a lot of algae while my glosso grow miserably.

If one can find an explanation to this..miracle.

is the box located in a green house or under some shade cloth? did he have anything for water movement?

If you have adopted an EI dosing mindset which requires nutrient overdosing, then this will seem like a miracle. The reason you can't grow Glosso and have algae is specifically because of excess concentrations of nutrients.

The box is on half shaded balcony at the first floor of this townhouse, it receives a lot of direct sunlight..likely half the entire daytime. He has nothing to move the water.
As for my water, I am quite certain that my water is less loaded in Nitrate and phosphate than his. I am asking him to measure the parameter of the water in his box.

Many soils have organic content that degrades aerobically and produce co2, one possible explanation of this success.

That makes sense, the substrate is made of a commercial biological nutritive sand, a commercial garden compost and gravel. Is the degradation process you mention easily reproduced in a tank ? I regret not having followed his method.

Yes it does, but at one point the organic content depletes and no more co2 is produced this way.
