API CO2 Booster, 450g

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.

I thinks it's a good product not harming my delicate fishes

Been using it for more than a month. I am definitely seeing good improvement in the plant growth. I have a 4ft planted tank with all essentials of a planted aquarium but no CO2. Would highly recommend this product. As always with planted tanks have to be a little patient.

Good

nicely packed , good quality. Cap helps in measurement . But expensive

old stock send. want a replacement with new stocknot able to return.

Works fine

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

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.

It works and helps my plants stay fresh and green. It had no effect on my fishes. It is better to buy a bigger bottle as it’s cheaper than the small ones and it’s better if you have a big fish tank like I do plus it’s easy to use. Great quality would recommend.

I got a big bottle of API Co2, thinking it'd help my aquarium plants. But it doesn't really do much for them; it actually helps with algae control. I still haven't finished this bottle, and I use it on five tanks: four 10-gallon tanks and one 36-gallon tank. I love all API products, but this one's different because I bought it for one thing, and it ended up working for something totally different. The bottle was sealed, and it'll last you for months since you don't need to use much. It's safe for shrimp, fish, and snails too.

I've only ever run low tech tanks with a few super-easy plants but I went a bit mad with my newest tank and splashed out on a bigger variety. All seemed well until my hygrophilia, limnophila and ludwigia super-red started rotting from the ground up. Never really felt the need to try co2 booster but this pushed me to do so. I noticed the difference after literally 3 or 4 days, and all of my plants have really bounced back. They're no longer losing leaves, and the new growth looks super healthy. Now that I've seen what this can do I'll probably always use it in the future. Highly recommended.
