How many dose iron and in what form?

[MisterP]

Plantbrain, Sort of following along here but could you briefly explain the benefit of dosing the DPTA iron? Sorry if I missed it but I just don't understand the role of iron for coral or macro. Does this help with coloration and general "health" or something else?

Here is my very basic understanding, hopefully Plantbrain can fill in the details.

Chlorophyll uses iron for photosynthesis and looks green. When you have a system with macro algae, mangroves, green nuisance algae, and zooxanthalae, which all use chlorophyll for photosynthesis, you can deplete iron quickly. This can be seen when green corals start looking yellow. The DPTA keeps the iron suspended in the water and allows less frequent dosing.

Thanks. So how do you dose the powder form of DTPA? Is this the same as the Sequestrene?
