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

  • 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

Amazing!
Color: Cyano Pink Spicule
This makes my skin feel so smooth. The appearance of my skin also is starting to look a lot better/younger. I've been using it for a week and a half already seeing changes.

Brightens, doesn't firm
Color: Cyano Pink Spicule
I've been using this for about a month now, every night on my face and neck, hoping to reduce the appearance of wrinkles and tighten some of my skin in that area that seems to be losing elasticity. On my neck, I've honestly noticed no real difference in 4 weeks of continued, consistent daily use. The skin on my face does seem brighter and somewhat less textured than before, but I haven't noticed any change in the issues I was hoping this would resolve, based on the claims and how it was marketed. So... not a bad addition to my skincare, but not the solution I was looking for. Some have expressed concerns about it tingling or stinging... You can feel something when you apply it, it's almost like the feeling of static electricity, but it's very mild. I wouldn't let that stop you from giving it a try if you were concerned about it. It didn't cause my sensitive skin any breakouts or redness (although I was applying it at night before bed, so perhaps any redness was calmed overnight). I'm going to go ahead and finish the bottle, but based on these results, I probably won't repurchase.

Helped Tighten My Skin & Minimize Pores
Color: Cyano Pink Spicule, Color: Cyano Pink Spicule
I’ve loved the Dr. Melaxin Cyano Pink Spicule Serum! The bottle is small, but it lasted me around 6 months since I only use one pump every other night. When I first started using it, I noticed a tingling sensation, but over time my skin adjusted and I barely notice it now. I’ve definitely seen my pores appear smaller and my skin feels tighter and smoother after using it.

Great for pore reduction
Color: Cyano Pink Spicule
This product works great!! it almost feels like an exfoliator. It reduced the pours on my nose, which were very big and now you can barely see them. I would recommend this product if you have large pores also make skin look firmer and smoother more for a night cream though.
