This is the result after 2 weeks
Left is from 20 gl tank and right is from 10 gl tank. It’s pricy and it’s didn’t cycle the tank in less than five day. I wouldn’t recommend using this product and putting fish/shrimp in after five days. Oh wells still sticking with the old fashion way of waiting 4-8 weeks with other additives.
My tank was going in and out of cycling for months. Could never really get there all the way. Added FritzZyme and two days later perfect balance! All parameters perfect. Staying that way too. Can't recommend this product enough!
