About this product
Potassium for a planted aquarium comes in this 100 mL / 3.4 fl. oz. bottle from Seachem's Flourish line. The label also lists a 250 mL size, and that larger bottle treats 50 US gallons for 4 to 6 months.
Bottle size and the 250 mL reference
The bottle holds 100 mL / 3.4 fl. oz. of the potassium solution. Measured in millilitres, that volume reads as 101 ml on some labels. The 250 mL size on the label treats 50 US gallons for 4 to 6 months, so the 100 mL bottle holds a smaller share of that quantity.
