If so, why? What differences have you noticed?

Edit: By "Extra Iron" I mean iron above and beyond what is already in your trace element dosing. Dosing CSM+B alone would make you a 'No' vote.

Gomer

35g plantex CSM+b in 500mL.
2mL/10g 3x a week. That is it.

After i start using iron my plant health improved specially red plants and they grow faster too

I dose the standard CSM+B mix regularly (EI), but dose extra iron (seachem) when I notice deficiencies. Very easy to spot, especially when I had swords.

I noticed with daily dosing they do much better. I dump a lot in, maybe too much, but the tank looks great (~20ml+ TMG/Day). If I miss a day, especially two, I can see the plants starting to suffer)

I use 1 ml/gallon/week of flourish and 0.5 ml/gallon/week of flourish fe.

Without it, my Hydrocotyle shows chlorosis between the veins and the reds in my Ludwigias and Didiplis are less intense.

AaronT

I dose about 1 ml / 10 gallons every day of trace and iron separately. I notice lusher growth this way.

trenac

I add extra iron; 1cc per 10 gallons of water. I've always done this so I cannot comment on any improvements. I have never had a iron deficiency though.

Cavan Allen

Absolutely. I add the same amount of Flourish Iron as Flourish. Lusher growth and better color are the result.

DubSack

I use 1 Tsp of CSM+B in 250 ml of water. then I dose 1/2 ml per gallon of water. So I end up dosing 30 ml's three times a week.
