Seachem Prime Water Conditioner, 50 ml

Great product and such a small amount required at water change.Highly recommended. I used for my newly hatched Axolotl and also my tropical fish tank.

Brilliant item

I bought two bottles of prime as I was nearly finished one that I had for years.I opened the new bottle and I got a bit of a shock. All the bottles of Prime that I have had in the past have been clear, this one, the liquid was black. I really didn't want to put it in my Goldfish tank but I had already half emptied it to do the water change. I went online before refilling my tank and read on a forum that somebody had the same issue and had contacted Seachem directly. Seachem said it was fine to use so I went ahead and a little reluctantly added it to my tank. Fish seem fine. I can't remember the whole response but it is something to do with the sediment in the bottom of the barrel (or whatever it is they mix it in) or something like that when they start a new batch and it all gets mixed up but it is totally harmless.That is what Seachem said, NOT ME. As I said I had to take a chance as I had nothing else and after I read what Seachem said I felt confident enough to go ahead and use it.My fish have been fine but it is up to everyone to make up their own minds if you get a bottle of black prime.

I have only used it today, and my fish already seem happier. I was going to Fish-in Cycle my tank (I know it isn't recommended, but my fishless cycle wasn't going anywhere). I ordered Tetra Safestart from Amazon, and unfortunately it was out of date, and therefore failed. Luckily, I had heard about Seachem Prime and ordered it right away. The ammonia in the tank was already quite high - at 0.75 - 1.25ppm, and I was already doing water changes.I'm hoping that Prime helps, and so far it seems to be working. It also seems like great value for money, as the 50ml bottle alone can treat 2000 litres of water.

I've always used Prime and will continue to do so. This smaller bottle has ahandy dropper cap. You use 2 drops for every 4 litres of new water. I buy bigger bottles and decant them in to this one so that I can be sure I'm putting the right amount in to my tank

Does the job!

The "go to" dechlorinator of most aquarists. Also gets rid of chloramines (many products don't). Chloramines are increasingly in use in the water as they don't disperse into the air as chlorine does, which is great for the water company, but bad for our fish. So no amount of standing or agitation gets rid of them. Prime also detoxifies ammonia and nitrite, so very useful if you get a spike, and need to treat it. Highly concentrated, even the smallest bottle treats thousands of litres.

Simple instructions on product. Easy to use for water changes. Recommended product.
