Ideal for fishless cycling, it provides a safe, controlled ammonia source to cultivate beneficial nitrifying bacteria, ensuring a healthy aquatic environment before introducing livestock. ## Description In most aquariums, the biological cycle is started by introducing fish into the aquarium. The fish excrete ammonia which acts as a food source for nitrifying bacteria. Nitrifying bacteria convert ammonia into nitrite and then nitrite into nitrate. Fritz ammonium chloride (nh4cl) can be used as a source of ammonia to initiate the growth of nitrifying bacteria without the presence of animal life. Fish should not be present while using ammonium chloride. Review: Works and plentiful left. - Works well for fishless cycle. Took about a month and a half to cycle a new 100gallon tank using this. Would be better if they sold it in a smaller capacity. Took like 50gms or lesser for a full cycle. I’m left with 450gs now. Review: Perfect for micro dosing cycles - Using this to cycle my new 90gl. My system has been running for a couple of months already, but I've been to busy to do anything with it since I set everything up. This stuff works great. Getting the measurements correct are a little hard, but I found that 1 tsp raises my NH3 to near 0.067 mg/l. The first dose took around 2 weeks to cycle. Once the ammonia levels dropped back to 0.001 mg/l my NO3 tested at near 5.0 ppm. The amonia levels from the second dose of 1 tsp is still reducing, but it's only taken 4 days to drop down to 0.018 mg/l. I plan on testing Nitrate levels once this cycle is completed and duing a 50% water change before dosing a third time. I think 3 to 4 cycles should be enough to stabilize the system. However, since I won't be adding livestock for another month or two. I'll probably add 1/16-1/4 tsp each day to feed the bacteria. I'll adjust that as needed. Hopefully, I can maintain my NO3 at 3-5.0 ppm with this. I definitely recommend this product if you want to save yourself some time. I prefer this method of micro dosing while cycling my tanks. I think it's easier to mimic a normal daily feeding schedule this way. Also, I get a pretty good idea of how my tank params will change daily when checking my system logs. I may increase my daily dose later about a week or two before doing a final water change and adding livestock. I use the Seneye Reef for active monitoring, and manually test the water weekly. ## Features - Pure ammonium chloride - Use for fishless cycling - High quality material - Country Of Origin: United States ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00OTH5TAQ | | Allergen Information | Almonds Free | | Brand | Fritz | | Brand Name | Fritz | | Customer Reviews | 4.7 out of 5 stars 4,042 Reviews | | Global Trade Identification Number | 00080531895009 | | Included Components | 89500 | | Item Form | Powder | | Item Type Name | Fritz PRO - Ammonium Chloride - 500gm | | Item Weight | 0.46 Kilograms | | Item form | Powder | | Item weight | 0.46 Kilograms | | Liquid Volume | 1 Cups | | Liquid volume | 1 Cups | | Manufacturer | Fritz Aquatics | | Manufacturer Part Number | 89500 | | Model Number | 89500 | | Target Species | Fish | | UPC | 781163682493 080531895009 | | Unit Count | 500 Grams | | Unit count | 500 Grams | ## Product Details - **Brand:** Fritz - **Item form:** Powder - **Item weight:** 0.46 Kilograms - **Liquid volume:** 1 Cups - **Unit count:** 500 Grams ## Images ![Fritz PRO - Ammonium Chloride - 500gm - Image 1](https://m.media-amazon.com/images/I/61T0GhILgGL.jpg) ## Questions & Answers **Q: Is 1 teaspoon good for a 10 gallon?** A: 1 teaspoon is way way too much for 10 gallons. Less than 1/8th of a teaspoon for 10 gallons - I'd suggest 1/16th. **Q: How much do I use for a 75 gallon tank?** A: One level teaspoon of ammonium chloride is approximately 4.5 grams, 4.5 grams per 100 gallons of aquarium water will create an ammonia concentration of approximately 4 ppm. I would start with half a teaspoon. Check the level of ammonia, if you still haven’t reached 4ppm then add smaller doses until you do. **Q: Typically you try to keep chlorine out of an aquarium (esp. saltwater). My goal is a fishless cycle; is there a reason to use nh4cl over pure nh3?** A: My thought is that the dechlorinator used in water changes should remove the chlorine put in when using the Ammonium chloride. It worked for my fishless cycle. **Q: How much do i put in for a 55 gallon tank?** A: Depends follow Mr Crafty Pants on YouTube. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works and plentiful left. *by G***A on 13 November 2021* Works well for fishless cycle.
