Fritz Aquatics FritzZyme 9 Live Nitrifying Bacteria Naturally Removes Amonia & Nitrite for Saltwater Fish (8-Ounce)

I used Fritz Aquatics FritzZyme 9 Nitrifying Bacteria and it worked greathere's the story I have a J BJ 29livestock one clown fish, one fire fish, one blue green chroma's, and a very small flame back and Angel 1ina fire shrimp blue hermit crab and some snailsthe tank has been extremely peaceful no fighting whatsoever.Then one day the flame back became a problem he's only 1 inch and after about six months. He decided every rock in the aquarium was his. Started aggressively protecting it would pick the shrimp up and drag him off the rocks.He had to go I had a 10 gallon set up with a pair of clown fish I put a divider in flame Angel on one side clown fish on the other.Had to set up a tank fast I looked on Facebook marketplace and found a 30 gallon not far from the house for $10 still had stickers on itSet it up with what I had laying around the house a very old hang on back filterand to sponge bubble filters. Made 20 gallons of saltwater. Filled the tankand ordered Fritz nine on Amazon. It arrived at 9 o'clock AM the next day32 ounce bottle. I I poured it in let it circulate for about an hour .Put the fish in some old salt buckets . And dumped the 10 gallon tank into the 30 gallon tanksand and to large conch shells acclimated the fish and dumped him input some old Constantine tiles from a bathroom rebuild to make some hiding places .And everything has been living happily ever afterThis stuff is great not only for its intended use of starting a new tank or boosting the bacterial load .But it's ability to be used in an emergency situation is amazing .It literally saved a a couple of hundred dollars worth of fish .Thanks Fritz

Surprisingly this stuff actually worked for me. Started my tank with old dead dry rock and Fiji pink “live” sand. Nothing from any established tank, no fish, no coral, about as dry start as it gets. Dumped in this bottle and dosed ammonia up to 2ppm. Within a couple days ammonia was dropping so I dosed a bit more. Tank was clearing ammonia in about a week. Did a big water change to drop nitrites and trates and added a couple hermits. By week 2 the tank was already at 0 nitrites and still clearing ammonia so it’s not just suspended bacteria in the water column. Also changed filter floss during this time and that had no effect on bacteria colony.Be sure to read up and understand what you are doing. Even with this stuff I always recommend a fish less cycle!

I've been using this for a year, and add it to my tank after every water change. It works wonderfully and does what it says. Though I didn't read the fine print on how much to use, I was not using enough. 60ml for every 5 gallons. I definitely was not using enough, though it still worked with what I used. Now, using the correct amount my SW tank looks even better, and certainly helps keep it stable. Having a 25 gallon tank has its challenges, and Zyme 9 helps combat any lack of beneficial bacteria my tank may need. I would highly recommend using this as part of your water change regiment. It won't fail you, and it used for tanks with New Tank Syndrome and Established Tanks, just be sure to add the correct amount as stated for what your intended purpose is, it won't kill anything, but too much of something could damage your coral. This is also great to use just after treating your tank and do a water a change to recover quickly. I had cyno bacteria in my tank, I treated it for a few days, killed it, did a water change, and then added Zyme 9 and next day my tank looked beautiful.

used it to start the cycle on a 40 breeder drilled with a 20 long sump. it seems to have boosted the cycle time for sure I'm still in the nitrite faze and Im about 3 weeks in maybe just about a month actually not exactly sure. I added a dead crab on day 1 and I added some food to create waste in the system and began dosing this. it got me into the nitrite cycle pretty fast the ammonia didn't last too long. id say based on testing that I'm close to being done with the nitrites. they are dropping little by little. its a bare bottom display but I do have a lot of live rock. sand is in the fuge section of the sump along with bio ceramic bricks. so I guess its not technically a full blown bare bottom. things are going well though

Update: So the Fritzzyme is kicking butt when it comes to Ammonia and Nitrites. Ammonia never going above .25 ppm (which is something I never accomplished before this), and Nitrite is always zero. Nitrate, however, is the new issue. Seems like the bacteria gets ammonia to Nitrate and then quits. My Nitrate levels are getting to 100ppm, causing me to do water changes to get it back down. Contemplating Red Sea Nitrate Remover bio to finish the job.So my review was originally going to be a 2 or 3 star, but given some time the Fritzzyme seems to have finally kicked in. But, upon adding the liquid I decided to do triple recommended dose; it says you can do 10x, as my small aquarium was struggling with Ammonia, constantly reporting 4ppm. I was using another bio liquid that didn't seem to be cutting it. I did a 33% water swap and added the Fritzzyme. The first thing that sucked is I think the bacteria seemed to throw off the algae in my Blue Blubber Jellyfish, and he died within 24 hours -- it was sudden and swift -- of adding the liquid. I tested the water about 24 - 30 hours later and ammonia was still at 4 ppm. I was bumming on this but then tested 48 hours after the first test and the ammonia is down to about .5 to 1 ppm. I know it's not exactly zero, but definitely has to be from the Fritzzyme kicking in. So definitely working.
