Weird white dots on my Vallisneria?

Recommended Posts

So I know I just posted this, but I also just found out what exactly was wrong with my plants. They’re suffering from biogenic decalcification. Basically there is an imbalance of light and co2. The light levels are telling them they should be able to grow at a certain rate but there’s not enough co2 for them to grow that fast. So they take in bicarbonate and break that apart into co2 and hydrogen peroxide. This gives them the co2 they need, but the hydrogen peroxide released reacts with calcium in the water to form calcium carbonate, which are the deposits that are on my plants. So either decreasing light exposure or increasing available co2 is how to fix this.

This video explains all of this and more, but figured I’d give a tldr for anyone interested.
