Use the WaterRower Blue Dye add a deep blue colour to the water in your tank.

Please note:

Blue Dye does not contain any cleaning agents and will not prevent algae growth. We recommend using distilled water with the Blue Dye, this is better suited for limiting the algae growth without impacting the performance of the Blue Dye.

Purification tablets should not be used in conjunction with the Blue Dye as this will cause the dye to clear.
