How much sera floredepot is required for a 150 liter (33 US gal.) aquarium, and how long do the nutrients last?

Hello,

the sera floredepot layer should be about 2 cm (0.8 in.) high.
This would be about 8 liters (1.76 US gal.) or 13 kg (28.7 lb.) for an aquarium bottom area of 100 x 40 cm (39.4 x 15.7 in.) [160 or 200 liters (35.2 - 44 US gal.), depending on the height] if you distribute sera floredepot on the entire area.

The actual requirement is probably lower, since usually not the entire bottom of an aquarium is planted. Simply draw a sketch as viewed from above, as to find out about the actually planted area.

The nutrients supply the plants for about 4 - 6 weeks during the initial phase, afterwards sera floredepot simply remains in the aquarium as a soft bottom ground through which the plants can easily grow their roots.
