Seachem Replenish – 4L

Seachem Replenish is a balanced blend of soft and hard salts that puts back the minerals removed by reverse osmosis or deionisation. It restores calcium, magnesium, sodium and potassium, making purified water suitable for freshwater fish and plants. This is the 4L bottle.

Using it with RO water

Replenish is for keepers who filter their water through reverse osmosis or deionisation, which strips out the minerals that fish and plants need. Mix it into a bucket or storage container of purified water rather than straight into the aquarium, stir until fully dissolved, then test GH and adjust until you reach the level your fish need, whether soft for tetras and discus or harder for livebearers. Once you know the amount that hits your target, use the same ratio every time so water changes are consistent. Choose the 500ml bottle for a single tank and the 4 litre bottle for fish rooms or large systems.

Good to know

Add to RO or DI water before use and test GH to reach your target.
