KramerDrak Special Iron Complete Fertilizer for Strong Light Tanks

Special Full Iron Fertilizer for intensively cultivated plant tanks

These include strong light and very densely planted tanks. Developed by Hans-Georg Kramer.

The aquatic plant specialist and author Hans-Georg Kramer experimented for many years to develop a fertilizer that shows its special qualities in well-planted aquaria, especially if these are also well-lit.
The use of four different chelators in a special proportion and an extremely wide range of trace elements, including so-called “beneficial elements”, helps to cultivate even the most demanding plants.

Dosage instructions

First of all, please determine the effective quantity of water in your aquarium; when doing so, deduct the volume of the substrate, interior filter and large-volume items of decor. It is easiest to measure using a ruler or a tape measure.
Then work out the lighting factor by adding up the number of watts of your fluorescent or halide lamps and then divide the total by the net capacity in liters of your aquarium.
For water levels of up to about 40 cm you may multiply the number of watts of T5 fluorescent and halide lights by a factor of 1.2, in order to take account of their greater light intensity and corresponding effect at depth.
The calculated lighting factor only applies if you are using the highest quality reflectors; without these, only about 50% of the light is available in the aquarium. The lighting bodies should have optimum ventilation, because less light is produced by lamps at higher temperatures.

• For medium lighting factors of about 0.4 W/l you will require approx. 10 ml / Week / 100 l Water of KramerDrak.
• For strong light aquaria from 0.5 W/l upwards we recommend approx. 12 ml / Week / 100 l Water of KramerDrak.
• More than 15 ml / Week / 100 l Water of KramerDrak will not bring about any further improvements.

The luminous efficacy of a fluorescent or metal halide lamp with electronic ballast is roughly 70 - 90 lumen/watt. This means that the above data can be converted accordingly for current LED lighting.
