Dr. Tim’s Aquatics Saltwater One & Only Nitrifying Bacteria – For New Fish Tanks, Aquariums, Water Filtering, Disease Treatment – H20 Pure Fish Tank Cleaner – Removes Toxins – 4 Oz.

Dr Tims is the best for starting new tanks

The product does exactly what it is supposed to do. I had to tear down a reef tank after I had a big die off due to a power failure, and this is just what I needed. This is a very good product. I have used this product in the past for setting up new saltwater and brackish aquariums.

Is all it took to cycle my 30 gallon tank. Used api saltwater kit for measurement

Okay, for those trying to use this as a “cleaner” noting will do that except weekly water changes. This product is for tank bacteria startup. I have been keeping fresh and saltwater aquariums since 2003, there in no other tank bacteria on the market that works except this one. I tried more than I can count and this was the only one that enabled me to have a stable environment for my fish upon first fish placement in a few days to a week. One note, make sure you add ammonia drops to the water per instructions so the bacteria can multiply before adding your fish. If you want to keep fish without them dying to ammonia in the water, this is the product for you.

This product is great. Easy to use very clear and precise instructions. To be used to ammonia to go along with it and they sell that too. Would recommend to a friend or anybody else.

Worked perfectly to cycle my tank!

This product seemed to shorten the cycling time but it is hard to say for sure. I used this product without fish and just added ammonia and the tank was cycled within two weeks.

I have been using this bottle bacteria to start up 10+ tanks over the years and probably will continue to do so. I think what many people get wrong is either (A) they think the cycle is instant or (B) they follow the chart to a “T”. You don’t add the second drops of ammonium chloride until ammonia reads 0.4 or less and you don’t do water changes unless pH drops below 7. I’ve had tanks cycle in 9 days and I have had tanks take up to a month to cycle. Just be patient. Nothing comes fast or easy in this hobby
