9Cows: 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.

Amazon CustomerAmazon Customer: I purchased the API Co2 Booster Freshwater Aquarium Plant Treatment when I noticed that I had an active algae overgrowth indicating an imbalance of nutrient in the tank. Since the tank is fairly small, and I don't have an external CO2 pump, I thought I would give this a go. Within a week of following the dosing directions on the bottle my algae problem was significantly reduced, and my plants began a completely new growth cycle. Now a few months after using at a regular interval things are looking healthy and lush. A small bottle goes a long way, and so even though it is a bit pricey, it has been completely worth it! I would definitely recommend for any kind of live plant set up.

Amber: This stuff has helped my aquarium plants and it hasn’t even been a week yet. I was dealing with a little bit of melting but that has been taken care of now. It does seem like it’s helping with the algae as well.

Mikey: Cant say if it worked at all really . Had an absolute nightmare growth of string algae. Nothing seemed to work . What seemed to cure it was removing everything from the tank and soaking in 10 % bleach for at least 15 mins . Thoroughly rinse afterwards. These treatments will probably work if the algae is not to severe.

Rahul Anand: 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.
