Many people have asked me what I used to instant-cycle my new build. There are definitely many bacteria supplements out on the market, but after conducting much research and speaking to Shawn Hale at Fritz Aquatics, Lance Ichinotsubo of Elite Marinelife by Captive Seas, and Chris Meckley of ACI Aquaculture, I was sure that Turbostart 900 would be the way to go and I am glad that I did. Formulated specifically for saltwater, this strain of bacteria is a one of a kind denitrifying bacteria that simply works. In this video, Chris Meckley of ACI tells us how he uses them exclusively for his fish holding systems (2000 gallons each) when he bleaches them twice a year for preventive measures against possible parasites without any loss of precious fish lives. Have confidence, follow directions, and use the trusted products that are used by the pros. Enjoy!
