Iron source to augment TMG?

does tmg need to be supplemented for iron hungry plants? is macrandra an iron hungry plant? I've been using straight tmg. My reds are fine, but the lower leaves tend to fade very quickly on mac, so I end up with nice tops and a ratty plant anyway.. Any hints?

 

Adding TMG into the water column should be just fine, all you need to do is plant a few slow release fert tabs around the heavy eaters, this will provide them with what they need, youll find most of the very red plant types are all primarily root feeders rather than taking what they need from the water column, all these benefit from tabs, amazon swords and that type of broad foliage thick set plants will lap it up to.

The other way would be to carefully mix in some laterite with the soil around the heavy eaters, that will also slowly release iron to the substrate.

Both ways will mean you cater for the whole biomas rather than leaving things gasping/overfed.

 

Tom I had issues in 4wpg.. and not sure I"ve gotten rid of them in 2 watts, but I am certain I've had enough light one way or the other.

Florida aquatic once told me that their mac grows best if they put on a bit of it in tanks iwth other plants and it fades if they try to grow an entire tank of it.

there has to be a nutrient it runs out of.

If I'm dosing EI are their any other options?

I did the "low' nutrients thing originally .. it is better in ei but again, only the tops.
