Product Information

Seachem Replenish does just that. It restores the essential balance of processed water.

When tap water is processed via reverse osmosis or de-ionization, not only are all the pollutants and sediments removed, so too are the nutrients and minerals that are essential for a healthy aquarium.

It's vital to replenish these elements as it can cause stress to fish, leading to disease.

Replenish also restores the General Hardness (GH) of the water using a mixture of both soft and hard salts.


  • Add 5 mL (1 capful) Replenish to 40 L to raise GH by 1 meq/L (2.8 dGH).
  • Recommended restoration level into DI or RO water is 1-2 meq/L which is 5 mL per each 20-40 L.
