แหล่งเหล็กที่มีความเข้มข้นสูง (10000 มก. / ล.) สำหรับตู้ปลาที่ปลูก
เหล็กเฟอรัสกลูโคเนต
เฟอร์รัสกลูโคเนตเหมาะกับการให้อาหารทางใบมากกว่าธาตุเหล็ก -DTA

จุดเด่น
ธาตุเหล็กเป็นสารอาหารที่สำคัญในตู้ปลา เพื่อรักษาความเข้มข้นของธาตุเหล็กที่เพียงพอควรได้รับปริมาณอย่างสม่ำเสมอ (ทุกวัน)
ควรใช้Flourish®ให้น้อยลง (ครึ่งสัปดาห์หรือทุกสัปดาห์)

Flourish®ทุกวันอาจทำให้สาหร่ายเจริญเติบโตได้

วิธีใช้
ใช้ 1 ฝา (5 มล.) ต่อ 200 ลิตร หรือตามความจำเป็นเพื่อรักษาธาตุเหล็ก
ขนาด: 50 มล. 100 มล. 250 มล. 500 มล. 2 ลิตร 4 ลิตร

Iron is immobile in plants. This means that plants cannot divert iron from older leaves to new ones. Therefore deficiency symptoms appear first on new or young leaves. Because plants use iron to produce chlorophyll a lack of iron results in chlorosis or yellowing of the younger leaves. Stems may also appear short and slender. If the deficiency is severe and prolonged each new leaf emerges lighter in color than the preceding leaf.

When choosing an iron supplement it is important to know the distinction between the two forms of iron. The iron will be in one of two oxidation states: ferrous having a +2 charge or ferric having a +3 charge. Ferrous iron the preferred iron form and is soluble in water at any pH. Ferric iron however is only soluble below a pH of around 5.5; but if the pH is higher than 5.5 which more than likely it will be in a planted aquarium the ferric iron will become insoluble and precipitate settling in the root zone. Once this occurs foliar absorbtion becomes impossible.

To overcome this precipitation competing products employ a chelate of ferric iron: iron-EDTA. While this does keep it soluble it has a couple of drawbacks with respect to foliar uptake of iron. (1) Iron-EDTA bonding is very strong thus very little of the iron will be available to the plants over a given time frame and (2) Physiological energy must be expended by the plant in order to extract the ferric iron from EDTA-iron and then convert (reduce) it to the ferrous form. Our approach is different in that we use a complex (not chelate) of ferrous iron in Flourish Iron™.

Flourish Iron™ is a highly concentrated (10000 mg/L) ferrous iron gluconate supplement. Plants are able to much more easily derive a benefit from Flourish Iron™ because ferrous iron gluconate is already in the ferrous form so they do not expend energy reducing it. Despite what other manufacturers may intimate gluconate is not harmful to plants or fish. In fact ferrous gluconate is better suited to foliar feeding than is iron-EDTA owing to the relatively weaker iron-gluconate bonding vs. iron-EDTA bonding. In addition ferrous gluconate has the added bonus of being a source of carbon.

***Directions***
Use 1 capful (5 mL) for each 200 L (50 US gallons) or as required to maintain about 0.10 mg/L iron. For smaller doses please note that each cap thread is about 1 mL. Use
MultiTest™ Iron test kit to monitor iron concentrations. Due to rapid utilization test within 30 minutes. Use as needed to combat signs of iron deficiency (usually seen in new
growth) which include: chlorosis (yellowing) of tissue between veins and short and slender stems.

Sizes:100 mL 250 mL 500 mL
