DrTim’s Aquatics Ammonium Chloride Solution for Fishless Cycling - 4 oz., Treats 200 gal. – Fish Tank Cleaner for Saltwater, Freshwater & Reef Aquariums

DrTim’s Aquatics Ammonium Chloride Solution has been a game-changer in setting up my new aquarium. This reagent-grade solution simplifies the fishless cycling process by providing a precise ammonia source, eliminating the need for guesswork. When used in conjunction with DrTim’s One & Only Live Nitrifying Bacteria, I was able to establish a healthy biofilter in my tank without subjecting any fish to harmful ammonia or nitrite spikes. The easy-to-dose liquid formula treats up to 400 gallons, making it both efficient and cost-effective. I highly recommend this product to both novice and experienced aquarists aiming for a safe and effective aquarium setup

Works as it should

Helped me cycle my tank in less than 2 weeks

Works great long shipping times

Great for starting new fish tanks

I ordered 2 2 oz bottles because I could get them overnight vs 2 days on the 4 oz bottle. This is my first time using chemicals to cycle a sw tank. I usually add some raw shrimp to a mesh bag. That way takes about a month to cycle a tank but it’s effective. I have a WB 230.6. The tank has 100+ lbs of dry rock and 120 lbs of Caribsea live sand. The dosage is 2 oz per 100g. Although some of the comments read to use half. I added bacteria the day before and both bottles of the ammonium chloride the next day. 24 hrs later I tested my ammonia using a Sailfert kit and it’s reading 1.5 PPM. I’m happy that the cycle has started but was hoping it would be 2 or higher since there are no fish in the tank. Now I’m asking myself to get to 2 PPM do I order more product? Start adding fish food to the tank? Or let it ride and see what happens?

Got the job done. 1 ppm was just fine for me though the 2 ppm would have been a lot.

So when I bought my 54 gallon aquarium... I did not know much. I was told at the LFS to buy this API quick start (good product) and some stress cost stuff and all good start adding fish... so I setup this tank and put the API quick start in and planted plants - one melted and the others did well but 3 days later my tank had a chalky appearance. So I took the filtering system apart EHEIM ( great product) washed the pre-filter and everything cleared. Perhaps it was the rotting plant? Needless to say I had to take the tank down and reset it up at home- same thing chalky after 3 days. So what I learned is that is a bacterial bloom but i provided no fish and no ammonia (fish excrement). So basically the bacteria bloomed and died. Ok I got this now. So did a 50% water change and started over again after receiving the DR Tim’s Ammonia Chloride. Put in API Quick start again and now added 216 drops of ammonium chloride- tested in the morning after. Ammonia was NOW at 4ppm. That evening tested and had a twinge of nitrite - just a barely there. Next morning tested and ammonia about 3ppm and definitely at .50 nitrite.Tested that evening now at 3ppm ammonia and 2.0 ppm nitrite - tested nitrate just a smidge.This thing is just rocking and rolling along in days!!! Only days !!!Following the exact path line! Wish I knew then what I know now - don’t use raw fish or raw shrimp or a bunch of fish food to generate ammonia - get a good product for starting quick with bacteria and this ammonia AN you’re set! This sooo speeds up the process!!! I’ll keep updating...UPDATE: next day: ok now ammonia is at 2ppm; nitrites at 2.00ppm; and nitrates SMIDGE... between 0ppm and 5.00 ppm. Plants in tank are thriving NOW!UPDATE 4 days in:Ammonia 2 ppm down from 4ppmNitrites 5ppm up from 2ppmNitrates now 10ppm up from trace5 days - ammonia 1 ppm (when it gets down to about .50 I’m gonna have to add some more in)- nitrites 5 ppm- nitrates 20 ppm now6 daysAmmonia at ZERO - gotta add a full dose again.Nitrites 2 ppmNitrates looks like 2 ppm a teensy bit darker but only a smidge - Nitrates going down?WELL water is crystal sparkling but apparently I have to add more ammonia....so gonna do itPlants looking REALLY good - I wonder if the plants are taking care of some of the nitrates?Tested Ammonia after 6 hours after putting it in and ammonia is back up at 4ppm7 daysAmmonia BACK DOWN to only .25 ppm!Nitrites at 2 ppmNitrate at 5 ppm <- I believe the aquatic plants are using up the nitrates! And keeping it in check.8 daysAmmonia 0 ppm (adding another 1/2 dose 2 drops per gallon approximately 106 drops)Nitrites 2 ppmNitrates 2 ppm
