DrTim’s Aquatics Ammonium Chloride Solution for Fishless Cycling: 2 oz., Treats 100 gal. – Fish Tank Cleaner for Saltwater, Freshwater & Reef Aquariums

This is a great way to get an ammonia source to start a tank cycle without having to sacrifice a fish or constantly be adding fish food. The bottle suggests 4 drops per gallon (1 per Liter), which seems like a lot but didn't seem to make a huge dent in even this little bottle in my 30 gallon tank. Will last a long time, although I would hope my cycle won't crash and I won't need it.

The real deal if u need to cycle ur tank, go on dr tims website for directions

One drop per gallon and ammonium level perfect.Be advised, if you do use this product and an API test kit -- the API test kit does not test for lower levels of NH4, only NH3, so your results on that test might show lower than what is actually present. This problem does not exist for kits from Nutrifin or other tests that specifically test for NH3/NH4.Using this product, I cycled one tank in 5 days with a bacterial starter. I did add a little bit more ammonium chloride to keep the bacteria alive because I didn't anticipate the tank would cycle quite that fast and wasn't ready to go buy fish to sustain the nitrogen cycle.There is enough in this bottle to cycle more fish tanks than any one person will have for many years.Do not use household ammonia to cycle your tanks trying to save a few dollars. They contain surfactants, buffers and stablizers. The surfactants you can test for by shaking the bottle, but you probably don't have lab equipment at home to reduce the cleaning product and find out what else is in there. Not to mention, this process would involve heating the ammonia, making your house reek and probably get you sick in the process.DrTim's product is solid and he has been in the business of providing fish care products for many, many years. He developed Tetra's Safe Start, as well as Bio Spira and his own One and Only bacterial starter that you can find here on Amazon.Thumbs up Doc!!

Right now i’m currently in the nitrite reading stage of the cycle. Took 2 weeks for that to happen. It also works way faster with a higher pH. My first attempt i had really soft and acidic water and there was no change for the whole month i was testing. After a water leak scare (false alarm) i refilled the tank and basically started over but added crushed coral. and like i said, it took about 2 weeks for nitrite to start showing which didn’t happen at all in the first try.This stuff works. Definitely faster than using fish food as an ammonia source.

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?

Great for cycling your fish tank.

It’s ammonia, nothing really else to say it works as it’s intended lol. I’m using this to cycle my tank and it works so, w ammonia.

Product had zero ammonia. Not sure if I just got a bad bottle, but I added half a bottle to a cup and still read zero. Had zero ammonia smell as well. Buyer beware. You may need multiple bottles to get a good one.
