My water looks amazing with this running and it also helped keep my numbers at zero since i leave the Carbon in for 3-4 weeks before changing it out and i have a huge BIO load in the tank.. Just make sure you buy the larger Carbon since the small grains will clog the reactor and end up in your sump i tried it and it doesnt work
