I wanted to get this out there and see what other people thought about it.

A while back I found myself dosing a lot of iron into my tank (Seachem iron at least 1 capful a day). But I started getting tired of sucking on the iron nipple (i.e. always needing it - and paying for it, $8 for 250ml per month is no fun) I couldn't find any chelated iron where I live so I thought I'd try adding iron pills into my substrate.

I did it and my plants have stayed really green. So it doesn't seem to have had any adverse affect (I added them about 4 months ago). And now I don't need to add much if any iron to the water (and really only for the floating plants).

The iron pills I use are:
Nature Made 65mg Iron tablets from Ferrous Sulfate.
Ingredients> Ferrous Sulfate, Cellulose Gel, Dibasic Calcium Phosphate, Croscarmellose Sodium, Hydroxypropyl Methylcellulose, Titanium Dioxide (artificial color), Magnesium Stearate, Polyethylene Glycol, Triethyl Citrate, Polysorbate 80, Sodium Citrate.
