Hi, I am setting up a new 10 gallon tank. I have treated the tap water but have not yet added this bacteria that I bought. Do I add fish before or after adding the bacteria? How long before or after should I wait? Thanks for your help! Amanda

Asked by: Mandyk
Hi Amanda, Add one fish, and while the fish is floating in a bag from the store, pour the bacteria into the tank after mixing it well. BREX

Hi friends! I'm looking to do a fishless cycle so my tank is good to go before I add fish. Would this product be okay to use, or do I need to have live fish for it to be effective?

Asked by: SlickBrew9225
You would need live fish for it to work properly as bacteria need a constant source of food. It is much, much simpler and faster to just add 1" of fish for every 10 gallons of water, along with this, than it is to do a fishless cycle. You would safely cycle the tank in about two weeks, whereas fishless cycling often takes months, per customer feedback. BREX

I purchased a 4 oz bag of the aquarium bacteria and have a 3.5 gallon tank. How much should I put? Is the whole 4 oz safe?

Asked by: celestars1
It won't harm anything but you don't need that much. The pouch treats up to 20 gallons of water. We would recommend approximately one quarter of the pouch. BREX

I put an entire 4 oz pack in my 5 gallon tank. Will this be a problem?

Asked by: Tstall
No. It will cloud the water for a bit, but eventually clear. It's just bacteria and will not harm anything. BREX

Is this product safe for stingrays. does it have copper in it?

No, there is no copper in it. It is safe for all freshwater life, as it is only bacteria found naturally in aquatic environments. BREX

Can I use this product in my salt water tank

Asked by: Jimmy8189
It would not really be beneficial to a saltwater tank. You need Instant Ocean BioSpira, which we also make. BREX

Should the bacteria go in before the stress coat chemicals?

Asked by: Victhejap
No, you would add your water conditioner, wait 5 to 10 minutes, and assuming there are fish in the tank, add the bacteria. If you do not have fish yet, then do not add the bacteria until you add your first fish. BREX

If it doesn't work to cycle quickly as stated, is there any way to check if the bacteria were actually alive to begin with ? I am wondering because if I open it I will not be able to return it.

Asked by: Dante167
If the bacteria die off (and we have never had one complaint regarding that happening) when you open the pouch, there would be a very foul odor. You can't tell anything without opening it, but it will work. If you have any issues, just call our Care Team about the guarantee, 1-800-322-1266. BREX
