API CO2 Booster, 8 OZ, multicolor, Fl Oz (Pack of 1)

Product description shows instructions and other labeling is in English. But the product I received is in Chinese. Seller could have provided English labelling or instructions with the package.

Useless not worth it

Great to boost aquarium plants, new set ups etc.

Excellent product .. was delivered in a well packaged form and have been using it on 2 of my small fish tanks and the plants have rapidly been growing well without any apparent harm to the fish. Good product and worth picking this up along with the API quick start . These two products enables me to keep the fish tanks balanced and healthy.

Just a bit expensive but really Do the job!!!!!

Using in a freshwater planted tank, our plants have never looked better. The plants are producing off shoots and the fish are doing fantastic. We use this CO2 daily on our fish aquariums!! When delivered cold The plastic did crack due to me dropping the bottle. I was able to save the contents of the bottle in the last bottle I bought meaning I buy this often. The size of the bottle is 8 ounces, fits under the tanks on the shelves well.

FIRST you need to know this is not a FIX for CO2 in your tank. NO. It however is a very effective algaecide. Algae require CO2 like all plants to Photosynthesise food. By killing algae you are basically making more CO2 available for your plants. Also if you keep any sort of algae grazers, like Ottos or even shrimp, this could reduce the food available to them. This is a very potent chemical - so use sparingly and as last resort as algae control.
