Should you reduce the amount of fertilizer if you have an algae problem?
There is no comprehensive answer to this question, as it requires a comprehensive analysis of the water, fertilization, lighting, carbon dioxide supply, and regular water maintenance. Algae are not only caused by an excess of nutrients, in particular phosphate and nitrate, but very often also by a deficiency of micronutrients, of which iron is the best known. This is very often the underlying cause of algae problems. When algae appear, it is generally highly recommended to increase the amount and frequency of water changes, ensure that there is a good stock of fast-growing plants, and then fertilize these according to the instructions with JBL Ferropol or JBL Ferropol 24.

Does JBL PROFLORA FERROPOL, JBL PROFLORA FERROPOL 24, or JBL ProScape Fe+ Microelements contain copper, which is harmful to shrimp?
All fertilizers mentioned for ornamental plants in aquariums contain copper, as do all good trace element fertilizers. Copper is an essential trace element for plants and animals. In shrimp and other decapod crustaceans, as well as some other animal groups, copper is even essential as the central atom of the blood pigment hemocyanin for oxygen transport in the animal. The concentration in JBL PROFLORA FERROPOL, JBL PROFLORA FERROPOL 24 and JBL ProScape Fe +Microelements is designed to contain the amounts required as trace elements. Even multiple overdoses of the fertilizer have no negative effects on shrimp and other decapod crustaceans.

I opened my bottle of JBL Ferropol two months ago and now "crystals" have formed. Do I need to throw it away?
The bottle of JBL Ferropol is not worthless. Please shake the bottle before using the fertilizer and then dose as you have done previously. Our fertilizer is highly concentrated, so in some cases individual nutrient salts may crystallize. Once these are in the aquarium water, they will dissolve again and remain effective. The chelated fertilizer components are not affected by this.

I would like to fertilize my plants with your product and switch completely. How should I proceed?
As a general rule, you should not change your plant fertilization regime abruptly. Fertilizers from different manufacturers vary slightly in their trace element composition. This can lead to temporary differences in the nutrient content of the water. It is best to make the change in three steps: 1) Reduce the old fertilizer by 1/3 and add 1/3 of the new fertilizer. Wait about 3-4 weeks and observe the reaction of the plants. 2) Reduce the old fertilizer by 2/3 and add 2/3 of the new fertilizer. Wait about 3-4 weeks and observe the reaction of the plants. 3) Stop using the old fertilizer completely and switch to the new fertilizer. It is important to observe the reaction of the plant growth on the one hand and to check the iron content of the water at least twice a week on the other. The value should never fall to 0, but should also not rise above approximately 0.2 mg/l if possible. Short-term peaks should not be taken into account. As a general rule, the measures should be carried out weekly, ideally after a water change. This will achieve better results than shock fertilization at longer intervals.

Does it make sense to use JBL Ferropol fertilizer when fertilizing with JBL 7 Kugeln?
Yes, that makes sense and is even recommended depending on the type of plants in the aquarium. The JBL 7 balls are intended more for root-consuming plants, as they provide the plants with nutrients via the roots. Fertilization via the water column with JBL Ferropol is generally recommended, as all plants, root-consuming plants less so and stem plants more so, also absorb nutrients via their leaf tissue.

Why is my Ferropol no longer olive green or yellow, but brown?
The color of Ferropol depends on the pH value. Ferropol is adjusted to a pH value of 4.5 during production. At this pH value, the color is olive green. During prolonged storage, and especially when bottles are opened, oxygen from the air enters the fertilizer over time, causing the pH value to rise and the color to change to a brownish tone. This has no effect on the effectiveness of the fertilizer or its ingredients. It can continue to be used without hesitation
