Great Product!!
The story starts with my old established tank being broken by relatives kid and it just broke glass on base and one side. i have large angels, peacock rainbows, corycats and bosemani ranibows. i decided to make a new tank instead of fixing the old one, due to the size issues i had to give it 3 days after siliconing it to let it dry out, by that time the bacteria in my filter might not have survived as there was no circulation in filter. i brought prime to cure my issue of new tank syndrome as it was going to be a fully stocked tank, thankfully i had my sponge filter working in bucket so it had the bacteria colony from my old tank. seachem prime did what it was suppose to do, it helped me set up a tank and i just lost 1 fish. Its costly but considering its a highly concentrated solution and you just need 7ml for 300L (my tank is actually 290L) it would last you a long time. if you use any chlorine remover, you can replace it with this. it also converts ammonia/nitrate. please do remember adding this is not the end all of your regular maintenance, you will still need to change the water depending on stocking level of your tank and tank size. i highly recommend this and in long run it turns out to be around same cost as any other item.

Value for Money
Highly concentrated require very less quantity to de-chlorinate my entire 150 gallon tank just 3 full caps....can use prime before directly in tank along with fish and use chlorine water directly into the tank during water change... dechlorinate water instantly

Does its job well. Must have for any aquarium
A must have for any aquarium. Been using it since 2 years now and works like a charm. Dissolves quickly and acts rapidly.

Life saver! Literally.
This is the gold standard of water conditioners. Its ammonia and nitrite removal in a bottle. Test water params with reagent based kit, like API, and use this if ammonia or nitrites are too high. Also use to dechlorinate the water.

Good to start cycling a tank
Good bacteria build up is seen and nice rise in levels of nitrates. Still in process of cycling can update the result later

Very good water conditioner.
Highly concentrated solution .only a amall amount of the liquid is needed to remove chlorine and chloramine .5ml for every 50 gallons .It will smell a bit like rotten egg but this is normal .will easily last for more than 6 months, unlike stress coat which is very diluted when compared to seachem prime and does the exact same thing !!
