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 👏

Works well but you do need good soil and fert combined

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

This product is very effective. I can see the difference in my aquarium. I think this is on a bit expensive side, but you see the difference in plant growth. somehow I love this product.
