Fritz PRO - Ammonium Chloride - 500gm

Per the safety data sheet, this is pure ammonium chloride. Great for home chemistry. Also great for party tricks as you can turn any beverage into Salmari.

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.

Nice

Bought this for cycling aquariums. Works well. It does its job.

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.
