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.

Key benefits

  • Liquid carbon source — supports photosynthesis and plant growth
  • Helps reduce algae growth, including GSA, BGA, and staghorn algae
  • Suitable for tanks with and without CO₂ injection
  • Safe for all aquatic life including shrimp
  • Includes graduated measuring cup (2.5–20 ml)

Dosing

  • Daily dosing recommended
  • Dose during or shortly before the lighting period
  • Best used in combination with MasterLine I + II or an All In One formula

Good Sized Treat for a 35 llbs dog, smaller it will interfere with daily meals.
Flavor Name: Chicken Chips, Size: 1 Pound (Pack of 1)
The texture is hard as a chew treat, my two small dogs can smell the container being opened and tapping my leg to give it all to only one. Size is one chicken piece rolled tightly, so i have to cut it up completely and share it between my 15 yr old MinPin and my 2 yr old miniature shepherd mix. This will be used only every other day so it will take about a month or more to us first of two bags. The cost also drew my eye and the fact that just two ingredients which should not affect the health of my MinPin.
