Fritz Fishless Fuel - Ammonia Source for Fishless Cycling (2 oz)

Overall, a great product and serves its purpose well. Tested my water before and after and saw definite results. Will buy again if I need to.

Been using this to cycle my 20 gallon cube tank I recommend under-dosing before doing the full drop amount on the bottle. it wanted 40 drops and I did 30 w a nice active cycle. I’d recommend 2-3 drops instead of 4 per gallon. Works great tho!!

Worth it for fishless cycling - worked very well.

It does what it's supposed to do. I'm on day 15 of my tank cycle using this product and it's still in progress, but we're moving along as expected. Don't let other reviews fool you into thinking that this works in just a few days or a week. You have to wait for both ammonia AND nitrite levels to decline to zero during the tank cycling process. While ammonia takes just a week to process, nitrite levels remain high for WEEKS and require many water changes before levels will stabilize. Remember to add de-chlorinator BEFORE adding new water to your tank so you don't kill the bacteria you're trying to grow. Right now, my tank is processing about 1ppm of ammonia per day, but it's still growing the bacteria that converts nitrites to nitrates, so these numbers continue to spike. Be patient, give it time. Treat your growing bacteria like part of the family, and you'll have more fun with this boring process. Recommended steps: 1) Add this ammonia. 2) Add nitrifying bacteria. 3) Wait 4 days and retest. 4) Add a few more ammonia drops if the level is lower. 4) Wait for nitrite to spike to maximum levels, then perform an 80% water change until it drops within readable range. 5) Wait for ammonia to drop to 0, add more ammonia (just a few drops, I don't recommend repeatedly dosing with 2ppm ammonia during nitrite spikes). 6) Perform 80% water changes every time nitrite spikes to maximum levels on your chart. 7) Repeat adding small amounts of ammonia until nitrite levels start to drop within 24 hours. 8) Once both ammonia and nitrite repeatedly drop to 0 in a 24 hour period, you're ready to roll.

Fritz is great to start fishless cycle instantly. I would suggest using only half of the recommended dosage on the label. I used the recommended amount in two different tanks and both jumped to 8ppm in ammonia overnight. I had to do 1/2 water change to bring it down to 4ppm. So definitely use half of the recommended amount.

Cycled my tank in 7 weeks using this ammonia as well as seachem stability, a heater set to 82 and using the api freshwater test kit! I did only need to add about half the amount the bottle suggested to get the ammonia to 2ppm

Highly recommend ive been trying out fishless cycle products for a while now. Worked great in my new 40 gallon planted aquarium

Does what it says it’s supposed to.

It's ammonia for cycling a new tank, it does what it's supposed to.

I haven't used it yet since I'm waiting on my water box to be delivered. Calls this stuff is is ammonia chloride. Start with half a dose and in a few hours see where your ammonia level is at. If you want the tank to cycle faster just aim for .2ppm. if you want more stability after your cycle then aim for .4ppm. that way you're pretty much guaranteed to get no ammonia spikes after introducing your fish friends. Don't forget to pick up a bottle of Fritz zyme 9 or Turbo start because that is your denitrifying bacteria that will make your tank cycle quickly.

Worked great at getting my aquarium to cycle it was fast

When dosing keep in mind your substrate and decorations take up a few gallons at least! I have an 8 gallon tank but dosed it as if it was a 6 gallon and it worked perfectly

Recently used this to cycle my 75 gal tank. Be careful when dosing. Instructions say 4 drops per gallon to achieve 2ppm ammonia level. After dosing 4 drops per gallon, and being very diligent when counting, I was closer to 4ppm. I know pH level of your water will have an impact on this, but just be careful. I would dose on low side, then test your water and if you feel you want it higher, dose a bit more. Good product but I give it a 4/5 based on the instructions.
