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 (10,000 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.

Damaged or Perished on arrival
We pride ourselves on the quality of our products, and will never knowingly send out sub-standard or faulty products. We use trusted shipping partners, Royal Mail and DPD, because in our experience they are the best. However, accidents do happen, especially when you are in the business of selling glass and plants!
Unfortunately, we cannot take responsibility for plants that perish or deteriorate once they are in your aquarium or terrarium - the reason is simple, all aquarium and terrarium set-ups are different, and all plants have different needs. Doing your research ahead of time is all part of the learning process, and we hope our website provides enough information for you to make an informed decision. If you need more information about a product, or are unsure if it will work with your set-up, just get in touch, we won't bite!
Evolution Aqua (EA) Aquascaper aquariums are shipped directly from the manufacturers warehouse. Delivery is within 14 days, but normally sooner than this. There is an additional delivery charge on EA aquariums of £49.99 due to the size and nature of the product. You will receive a call to advise of a delivery date so you can be in to accept delivery.
All other aquariums can be shipped but may be classed in our 'Heavy Shipping' rate if the total order is more than 20kg.
Hardscape & other heavy materials
We pride ourselves on our extensive range of hardscape, but we understand it is not always possible to come and visit to touch and feel stone and wood in person. Please get in touch with us via phone (+44 (0) 1603 761900) or email (firstname.lastname@example.org) if you have a particular layout or shape(s) you are trying to source.
Given the nature of hardscape (ie it's heavy and expensive to ship!), we have had to cap free shipping at 20kg. The reason is simple, if a customer buys 3 x 15kg bags of gravel and 15kg of stone, this costs us over £50 to ship to you - meaning we make little, or nothing on your order - unfortunately, to stay alive as a business we do need to make a profit so we can carry on offering quality products to our customers.
