API 579C CO2 Booster, 237 ml

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.

I have a low tech planted tank, i do add liquid fertz once a week but the plants were not getting lush. so i used some root tabs and started to add liquid fertz twice weekly. too much unused nutrients started to cause algae issues. the only solution was to either go with liquid co2 or co2 system. i did not want to invest a ton on money on co2 system so i decided to go with API. when i brought it, seachem Excel was not available. This works great as good as seachem Flourish Excel, within a week algae started to die down and the plant started getting lush. algae did a number of some of my plants but after using this for 1 month and i am happy with the results. the plants are lush and the algae issue is gone. i just wish they would make a larger bottle for cheap, the chemical used is not expensive but they market it as some secret formula and sell it expensive. the base indigent is derivative of glutaraldehyde and you can find many hospitals use it to sterilize medical equipment.

My plants are growing fast, fishes are happy and the water is crustal clear. I did not change the water for 2 months, running fine.

The product is good but cannot replace a CO2 setup, we can use this if your refill is not available

Works fantastic 👏

Better deal price wise than seachem excel. Result wise both equal

Works great!

My plants started melting and I did immediate water change as soon as I noticed. Kindly research well before buying maybe it didn't suit my ecosystem.

Great to boost aquarium plants, new set ups etc.

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.

I've been using this for a month. I have noticed a small, difference in the plants. But not much. I dont use CO2 directly, this is only used as on its own. My star rating is neutral as I cannot see any significant changes in my tank.

Useless not worth it

I had a bad algae problem in my planted shrimp tank with this nasty stringy algae. I’ve been putting this liquid in every morning and all of the algae is gone!! The tank looks so clean and healthy and all of my shrimp and little fish are doing well. Great product!
