830 Ammonium Chloride, 2 Oz Bottle

I have a 30 litre aquarium and am totally new to keeping fish. Having tried twice both totally unsuccessfully to cycle my tank with fish, having followed all the guidelines, I discovered you can do the cycling with ammonia ( something the fish suppliers failed to mention when I was struggling with my set up! But we're quite happy to sell me fish). I downloaded the ammonia cycling information from the code supplied with the ammonia solution. It is very informative and explains the cycling from ammonia to nitrites and nitrates very well and once completed you can then introduce your fish. The literature did say after 14 days my cycling took 23 days until I was happy the ammonia and nitrite levels were 0 each day. I then bought and introduced 6 danios...well success and very happy fish. My tank water is crystal clear, I did one partial water change after 19 days. I recommend setting up your fish tank in this way as it is so upsetting to loose fish during the cycling process. It's excellent value for money and providing you carefully follow the instructions you shouldn't have any problems.

Perfect for fishless cycling a new aquarium, I followed the instructions and my tank has cycled. Much more accurate then using fish food or household ammonia.

I used this with ATM colony and it took about 28 days to finish a fishless cycle. Working with the API test kit, I simply followed the instructions but it didn’t happen in the the short time stated but that didn’t bother me, it was done properly and the fish are not happy and healthy in a fully cycled tank without stress.

I had been feeding my new aquarium, fish food and bacteria but nothing had really moved on after several weeks. So I tried this and the cycling process, really started. Great service and product.

Used to use this product years ago when cycling my tanks as i was and still am against fish in cycles. You seem to have to used a lot more of the product in order to gain the right ppm of ammonia, also if memory serves me right there used to be a strong smell of ammonia if you dared had a sniff...Now there's practically no ammonia odour.. All points to a less concentration of Ammonia Chloride..therefore need to buy more.

New to aquatics- wanted to set up new tank asap to transfer black moors to a larger tank. This seemed to quicken this process

What can I say its ammonia in a bottle! Perfect for fishless cycle of an aquarium. Comes with dosing on the bottle of drops per gallon. Combined with the api masterkit you cant go wrong. Does seem pretty expensive for what it is though. A larger tank would need more than one bottle and so can be an expensive way to cycle. Other household ammonia products are also tank safe but I didnt want to risk it to save a few quid

Bought to get a fish-less cycle started in a few of my aquariums. The dosage guide is printed on the bottle and it just gives your cycle a kick-start. Easy to use and will last for an age as you are only using a few drops at a time. Recommended to get your aquarium up and running asap. You still have to wait for the nitrifying bacteria to grow, but this provides the ammonia source to feed them.

Dr.Tims ammonia is a great product for setting a baseline for your fish-less cycle. Sure you can go buy a litre of ammonia from the shop but then you need to do a little math to figure out the correct dose for the concentration your bottle contains. Then you have more ammonia then you will probably ever need for the remainder of your natural life. But with doctor Tim’s they have to all figured out for you and it’s consistent and repeatable as long as you can follow directions. The hardest part is waiting for your ammonia and nitrite levels to come down as your tank cycles. Combine this with Fritz 7 or turbo start and you have a fast lane to a cycled tank.

Really nice to have, for the purposes of accelerating the cycling a new aquarium without any animals in it. It lasts a very long time, as well. Provides an ammonia source, essentially food for bacteria, in order to accelerate their reproductive rate. Be sure to read all instructions and guides before you use this.

My aquarium size is 450L and I tried for 2 month to cycling and no result. I used DrTim's Aquatics Ammonium chloride 2 OZ and I put all in my aquarium in same time!! :-) and ammonia rise to Top after five minutes and after 2 days 0,0 and No2 rise too much, than didn't find colour for it in my JBL test!!! :-) and after 48h No2 showed 0,0 too. and now 2 discus are in Tank. amazing and Thank for this product.

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.

Produit absolument génial, fiable et facile à utiliser. Le seul problème était que j'avais besoin de 75 gouttes et c'était long à compter, mais c'est très facile à utiliser. Grâce à ce produit, mon aquarium était cyclé en deux semaines. Ils ont un site internet expliquant comment faire le cyclage pour aider
