DrTim's Aquatics Reef One & Only Nitrifying Bacteria – For Reef, Nano and Seahorse Aquaria, New Fish Tanks, Aquariums, Disease Treatment – H20 Pure Fish Tank Cleaner – Removes Toxins – 8 Oz., 402

Followed the directions to a T and it worked! 💪 Set up: Recife eco 40 - Carib Sea dry rock and live sand. Ai 16hd, Nero 3 wave maker, and Axis 40 controlable pump. Added after boi cycle 2 clowns, 2 cleaner shrimp. Added a week ago after turning on the lights: a small colony of birdsnest and a plating montipora. So far elementary parameters have stabilized. I've also added algea barn galaxy-pods to help win on any nuisance algea buildup. Will update this post as time goes on.

From starts to 4-5 months I am using this one and Vibrant to prevent bad algae bloom and red cyano. And it works and never gone in really bad phase of a new syndrome tank.

Cycles tank quickly if directions are followed

Cycled a 120g tank with Caribsea Hawaiian Sand, media balls (the ceramic ones) and dry man-made liverock. Used the ammonia by the same brand to get up to about 4ppm. By day 2 I had a massive nitrite spike and Ammonia was just trace. Added more ammonia day 3 to get to 2ppm. Added microbacter7 on day 3 as well. Nitrite spike did last about 5 days reading off the charts before it went to 0. Refugium was up and running when the Nitrites became readable (API test). I’m about 10 days in and am running at 0 ammonia, 0 nitrite, and about 10-20 nitrate.” With Chaeto growing nicely. I normally cycle tanks with gulf live rock and it takes about 4-5 days to get a stable tank setup. I’ve never really had the ups and downs of new tank syndrome. Will be interesting to see if I get the hair/bacteria/cyano blooms over the next few months.

As far as I can tell this stuff is garbage. I’m four days into what will supposedly be a 1 week cycle time and after using this stuff mixed with Dr Tim’s ammonia all I have is a tank with high ammonia and no nitrites. I followed all the directions as closely as possible removed filter media etc. and yet there’s no indication a cycle has begun. At this point when the cycle finally does start I won’t even be able to attribute it to this product since these cycles begin on their own without these additives. Based on my experience so far and the lack of help from their Facebook page (mostly tried to come up with excuses and blame me) I won’t be buying another Dr Tim’s product.

I used a bunch of different products for aquarium startup to create the bacteria. Bunch of fish loss over $400 in fish loss. No other product ever really worked. I put this product in within two weeks. I had a fully running fish tank with multiple different fish this is the best product on the market when it comes to starting a fish tank.

So far it seems to get the job done. Worked well for my 91 gallon red sea reefer 350. Got things started pretty fast. Was able to add fish in a week!

Used this to cycle my 104 gallon Saltwater tank Worked perfectly; would highly recommend, worked as described. I used the whole bottle.
