Legend Avalon


Legend Avalon™ Is an All in One fertilizer that gives the plants in your aquarium the important trace elements iron, manganese, copper, zinc, boron, molybdenum, and the macronutrients potassium and magnesium, nitrate, and phosphate.

Legend Avalon™ it’s very well stabilized with ascorbate, citrate, and gluconate - this means that the nutrients are absorbed by the plants particularly quickly and easily.

For this reason, the Legend Avalon™ should be used as a daily fertilizer and added to the plant aquarium every day.

If you want to fertilize the basic supply of your aquarium plants with micronutrients rather weekly, you should use the more stabilized Legend Elysium™.

In fertilized aquariums approx. 25% to 50% of the water should be changed per week so that there is no accumulation of nutrients in the aquarium water.

The level of dosing Legend Avalon™ is dependent on your plant stock level and the amount of light. The amounts below are designed for a fully planted tank under high light, if your aquarium is planted less than 50% planted then you can half the amounts of Legend Avalon™  fertilizer or you should use Legend Elysium™ which is specially designed and more stabilized
