The real thing

After trying numerous bacteria additives with no luck. This product actually does what it says, and as usual Chewy shipped it quickly with the bacteria still alive. Very impressed with your company. Thank you so much. Please stay safe and healthy

Dr.Tims One and Only

If you are doing a fishless cycle and you buy the Dr.Tims Ammonia Chloride the directions on the bottle say 4 drops per gallon, they are wrong, its one drop per gallon. I don't know how this could have happened but go to youtube and Dr.Tim explains how to do a fishless cycle.

Failed fishless cycle for a nano reef.

I bought a bottle of this product after talking to multiple other aquarists and doing research on Dr. Tims website. I was confident that this product would speed up my cycle. After a few days after adding the product nothing had happened. I ended up buying a different product that worked perfectly. It may have been a bad bottle but have heard great things about this product. I was disappointed.

Doesn't Work

Rebuilt a 75 gallon aquarium in early September. Tried a fishless cycle but the tank had not cycled by 10/13 so I ordered a 8 oz bottle. It arrived on and was added 10/14. Tank still had not cycled by 10/20 (ammonia levels still high). So another 8 oz bottle was ordered. It was delivered and added on 10/22. Aquarium still has high ammonia as I write this on 10/27. Nitrites are now high so something is happening. Whether it has anything to do with this additive, I don't know. But I do know that the claim that you can add fish right away is not true. Had I added any livestock to the aquarium, it no doubt would have been dead or dying. Certainly not worth the risk. Would not buy again or recommend.
