AquaVitro Propel

First of all, AquaVitro is the professional or Highest Quality line of the SeaChem product line. With that being said,  the AquaVitro "freshwater plant supplement line" is more concentrated than even the very good SeaChem line. Even though it is a very big seller internationally, the reason you might not know about this "very good" product it that it can only be bought at stores, not on-line. Thus, not hawked by the on-line companies; take our word for it, it is probably the best  suppliment line on the market!

Iron is immobile in plants; this means that plants cannot deliver 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.

If iron is provided in the ferric form (Fe3+) then it must be reduced by the plant to the ferrous form (Fe2+) before it can be utilized. This process of conversion (known as reduction) requires the plant to expend physiological energy. propel™ provides iron already in the ferrous form thus enhancing iron utilization. In addition, propel™ contains a reducing agent that helps convert any iron present (such as iron from substrate) into the ferrous form.


Use one inner capful (7 mL) per 70 US gallons (280 L) of water three times per week, or as needed to maintain about 0.10 mg/L iron.

Note: The aquavitro cap offers multiple dosing solutions depending on the size of your system. Each inner cap thread is approximately 2 mL. The inner cap contains 7 mL, while the outer ring contains 28 mL (35 mL when both are filled to the level of the inner cap.) When filled to the top, the cap contains 49 mL.
