Seachem 437 Prime Fresh and Saltwater Conditioner - Chemical Remover and Detoxifier 1L

Great value, just can be hard to figure out dosing for small aquariums.

This is a great product. Been using it for years and really works very well. Great for the beginner who wants a aquarium.

I use this stuff for my 100 gallon indoor pond. ~ one capfull is required for 100gallons. Makes my life really easy. Ive been using Prime for over a year now and my fish are nice and healthy! (I refill the indoor pond with tap water - Prime helps make that water safe. I add this to the pond first, then add the tap water - which isnt the ideal method)

Never do a water change without it!

I was very happy with the size. I also did not realize that it also converts ammonia. I saves me from having to buy another product. Love it.

Excellent product.

This is a good product for most fish but they should give a warning about some more delicate such as German rams, couldnt figure out was was killing them until I stopped using this and changed to api quick start

Excelente producto

Seachem Prime is a top tier dechlorinator and should be used by every fishkeeper

always keep plenty of bottles on hand, only de-chlorinator that removes nitrates and ammonia. been using for 5+ years. one capful = 55 gallons
