I’ve been poking around on the internet, and I can’t find an answer. Using the search function hasn’t come up with anything on this site either. Sorry if this is a repeat.

I’m looking for a DIY Flourish recipe. I will be getting rid of all my tanks save one, which is very low tech. Just Buce, Anubias and moss. I have all the ferts from my high tech days, so I would rather not purchase Flourish, just make my own mix. My plants need a little something, but not much. I really don’t want to do EI on a low tech. Does such a recipe exist?

seachem flourish is basically a micro nutrient solution, with some calcium and magnesium. npk are also present, but in negligible quantities. search in/address your question to the fertilizers and water parameters section.

Seachem Iron isn't the same as basic micro nuttrients. For one thing it isn't chelated with EDTA or other less toxic chelators. Seachem uses Iron Gluconate, which is a real common ingredient in iron vitamin supplements. Which can be found in most grocers and drug stores.

if you read the post carefully, op was asking about diy seachem flourish (and didn't want to dose ei). so he doesn't need extra iron. flourish contains iron.

If you can read between the lines 'carefully' I was pointing out that you can make your own DIY Flourish equivalent easier with Iron Gluconate exactly like Fourish Iron does! I defy you to prove that Seachem uses EDTA Iron plus micros, (which is pretty toxic,) because it doesn't.

He was asking about making a DIY Flourish. Well, Iron Gluconate is a good start and it's readily available as iron supplement tablets.

From Seachem's product page:
Overview
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.
