Prodibio Start up, Bacteria Starter Kit, Fresh and Saltwater, 6/1 mL vials, 30 gal and up

First tried these from a vendor at an Aquatic convention. I am hooked! With close to 20 tanks, I have cycled media I could switch around. I use these as a boost to jump start the cycle in a tank, or if I see a bacterial issue. Since these are preserved in gas, not air, the biggest benefit is no expiration date, no refrigeration needed.the vials are very sturdy feeling, and they don't feel delicate. The way they are packaged, they should be OK with some rough handling. If you need to quickly cycle a tank, or boost your tanks BB, this is for you! Also- just got my 4th purchase of this product. There is now an expiry date of about 4 years. I'm hoping to get some to share with my local Aquarium club so they can try it.Serious Aquarists should have this in their supplies. It's super handy!

Works well and easy to use ; good quality product.used it for my 2 tanks.

I'm amazed at the quality. My reef tank has fully cycled in 20 days.

Worked amazing as an emergency ammonia control which at the same time cycled my fishtank, however instructions are extremely vague and not clear, I think I ended up using too high of a dose, luckily no problems though. Really wish they had better instructions atleast on their website!

Works GREAT! I have read all the reviews. Use sone test kits give you a false positive. So try other test. I have set up multiple tanks using this. From discus to freshwater puffers. Fully stocked. No problems. Setting up anther 60 gallon today, already have fish. Best of luck to others
