In strongly lit, heavily planted tanks, natural CO₂ levels can drop to near-zero. Without supplementation, this causes slowed growth, complete growth arrest, and the proliferation of algae.\u003c\/p\u003e\u003ch4\u003eWhy a Fully Saturated Concentrate?\u003c\/h4\u003e\u003cp\u003eAn unsaturated liquid needs to dissolve before it can be absorbed. A fully saturated solution cannot absorb any more water — meaning every dose of YOKUCHI GEN C saturates the entire water volume immediately upon dosing.
