API CO2 Booster Plant Treatment for Freshwater Aquariums, 237 ml Bottle

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.

Really impressed with this c02 liquid, Give it chance to work , it took about 6 to 8 weeks before the significant change .... Algae more or less dissapeared, plant grown increased and my java fern stopped melting I dose twice a day morning and evening keeping an eye on the water parameters. Seems the dosage guide is a little underestimated my tank is 90 litre so I mm every 38 litres ...on the bottle ... I'm dosing 3mm in the morning and 3 mm in the afternoon with no issues with fish or water peramametres. I've not tryed seacham flourish to compare but will when this runs out ... Overall good value for a low tech planted tank ! Just give it chance to work ......

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.

Good product, if I stop to using few days straight algae appear…

A decent buy to keep the plants looking their best.

Do the job as required

Used but water testing didn't see any difference

Installing a CO2 system is frankly not possible on my budget but I still want a healthy green planted tank. The CO2 booster seems to be working well after 3 weeks of use, doesn’t harm the tanks inhabitants (minnows and shrimp) and the plants are going well! Obviously it’s not a one and done, I also use root tabs/plant fertiliser and have a good substrate, but in conjunction with these things the CO2 booster is helping me make the tank Ive been dreaming about!

Great to boost aquarium plants, new set ups etc.

All my plants in my tank started flourishing after I used this I would recommend. I did notice it affected the snails in the tank though. Still great product.

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.

Best ever product in the market
