DrTim's Aquatics Waste-Away Natural Aquarium Cleaner, Reef & Nano 8 oz

I used this product plus also seeded with some small pieces of live rock. Tank cycled within two weeks. Delivery was quick and it was well packaged.

I bought this to just add diversity to my bacteria population so, I can't tell if it works or not but, nothing bad has happened lol

Works as promised

I add about 90ml per week to my 300 gal reef tank; I have large saltwater fish and water is crystal clear. Helps breakdown waste in the tank, pour it after skimmer, and enjoy the ultra clear water. Product recommended turning off skimmer for a few hours but I have not noticed any difference running it or not. Prolongs my water changes at least another 30 days. Follow initial directions, use 1/2 dose first week.

Works just as advertised good value for the money.
