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

This is the real deal with the same sulphur odor, size delivered as described - and about half the cost compared to local retailers.

I’ve always had ongoing water quality issues with my tank as I’ve made the common mistake of not waiting for the nitrogen cycle to take place, on top of buying fish all at once. I’ve spent tons of money on API QuickStart, AmmoLock, StressZyme, StressCoat, etc. API makes great products, but AmmoLock for example, binds ammonia into a non-toxic state, but still reads positive on the API Freshwater Master test kit. Which is fine because my little guys seem pretty happy and not stressed out. At the end of the day, that’s what hobbyists want, is for their creatures that are in the tank (against their own will and with the ability to do absolutely nothing about bad water quality except suffer!).

This will last you a super long time. Can of pop for size comparison.

Prime condition for my aquarium is all I use. It keeps my aquarium health with no issues. This is a great buy for the money.

Does its job and you only need a small amount

The item I received arrived unsealed and there was some sort of black sediment at the bottom. Genuine Seachem products are sealed and the one should be clear with no sediment. Goodness knows what is in this bottle.

Did what I needed

Love prime.

Great quality and Im using less than 1ml for every 15litres i put in to my tank, so its great value for money.

Really nice product
