Product description
BIO XD EXTREME DECOMPOSER
BIO XD Extreme Decomposer is a complex probiotic product, with each drop containing a rich community of environmental probiotics (1 billion CFU/ml). It includes Paracoccus denitrificans, Nitrifying bacteria, and Desulfurobacterium. It can simultaneously reduce ammonia, nitrite, nitrate, and sulfur-containing substances in the water. Through the vigorous action of the environmental probiotics and when used with an appropriate filter, organic debris and pollutants causing water cloudiness will be rapidly broken down. Within just a few days, it can significantly clarify the cloudy water without causing any adverse effects on the fishes, shrimps, snails, aquatic plants, or other inhabitants.
QUICKLY DISSOLVE POLLUTANTS
After the bacteria are established in the aquarium, they quickly target various forms of dirt, leftover food, and hard-to-clean pollutants in the aquarium, including waste in the substrate, breaking them down effectively. In just 8 hours, the bacteria will eliminate the majority of troublesome pollutants, allowing you to no longer worry about cleaning your beloved fish’s waste.
SLOW DOWN ALGAE GROWTH
Bio XD can quickly block the troublesome algae’s sources of nutrients (ammonium nitrogen and sulfur-containing nutrients), effectively slowing down the growth of brown algae, black hair algae, blue-green algae, and red slime algae. It rapidly converts various pollutants and harmful substances into a nutrient form that aquatic plants can easily absorb, promoting the rapid and healthy growth of various aquatic plants without causing any negative impact on their growth.
REMOVE TOXIC SUBSTANCES
Highly active at all time. Starts working immediately after addition, removes ammonia, nitrite, nitrate, and hydrogen sulfide, effectively blocking the nutrient sources of harmful bacteria. The nitrifying bacteria quickly becomes the dominant bacterial strain in the water, ensuring perfect water quality.

John M –
Was skeptical but eventually worked really well!
At first I rated this bad because it seemed to have no effect on sludge. But then after a week or two, I noticed that the water column would stay more clear whether I used a filter cartridge or not. But I still didn’t anything of it until a month later, for the first time ever, the sludge in my substrate started decreasing. Not talking about surface sludge (don’t ever have that), I mean the compacted layers of detritus inside the gravel. I would say it is decreasing at a rate of 0.5 cm per month. I have a 20 gallon tank with 1 inch of natural gravel substrate. So I guess I will keep using this product and be a little more patient for the bacteria to do it’s job. I guess the denitrifyer strains in this take a while to fully colonize my substrate…

TBH I didnât have much faith but boy was I wrong!! Donât hesitate just buy it. My tank was in its final stages of in fish cycling with somewhat of bio load. This stuff has my tank looking amazing! And fully cycled. Fish are doing amazing, that new tank brown algae is under control. My aquarium is so clear!!

Works better than I thought
Owned tanks along time, recently I moved, since then it’s been a battle keeping water clarity crystal clear. I put 2 caps full in my 30 gallon tank this morning (12 hours) and it’s damn near crystal clear. So id say somethings working here.

Results
Didn’t clear up as much as it said it would.
Helen Sawyer –
Seems to work
Went away on a 2 month vacation. Daughter in law took care of fish. Needless to say the tank was a little untidy when I got home. Changed filter and added this and everything is fresh and clear so I have to complaints.

It really works!
This stuff really works. I donât have to clean the tank so often now. I had to clean the tank like every other day because of unsightly algae. I have been battled algae for years and used all kind of additives but there was no help until I use this one. Thank you!
