MasterLine Carbo is a liquid organic carbon supplement for planted aquariums. It provides an additional source of carbon — the primary building block of plant biomass — that aquatic plants can absorb directly through their leaves. In aquariums without CO₂ injection, it supports plant growth and helps reduce algae. In CO₂-injected aquariums, it can be used as a complementary supplement for additional growth support and algae inhibition.

MasterLine Carbo is recommended for daily dosing and works best when dosed during the lighting period (5–10 minutes before or shortly after lights turn on), when plants are actively photosynthesizing.
