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

Been using this for over a decade. Fastest working and most potent mix Ive used.

El producto ha llegado completamente destrozado y no tenía pinta de ser del transporte sino de que ya venía así

brings down the nitrites and nitrates

Prime is something you always keep on hand. I pour mine into a spray bottle and know that 2 sprays = 1 cap. No mess, No measuring, just simplicity.

Great product

Does the job good

Great value for money delivered on time excellent product *****

Been a user of Prime for years and years. Its never let me down. I managed to get this 1L bottle at a pretty low price, approx the same as my LFS sells 500ml.

Love seachem

Great. Dose what it supposed to do. Value for money. Will buy again.
