Seachem Iron & Excel with the use of UV
Dear all hi,
I had a problem with my iron fertilization.
You can find a full description of my aquarium setup at http://www.aquaticplantcentral.com/forumapc/science-of-fertilizing/33480-where-does-my-iron-go.html
I added ~0.5 ppm of iron (using also your product Seachem Iron) and noticed that when using my UV lamp (24/7), the iron was disappearing after 12 hours (could not be measured). When I turn off my UV lamp, the iron could be measured even after 3 days (from 0.5 ppm to 0.25ppm). I know that iron test kits are not to be trusted but I get measurements in a wide range even they are not quite accurate.
I have read in discussions according iron that it is photosensitive, and I assume that this is my main problem. Having also read that Flourish Excel is also photosensitive, could you please inform me of what should I do in order my plants to get the proper iron they need? Do you know or suspect any problems with the concurrent use of a UV lamp and Seachem Iron & Seachem Excel?
Thank you in advance,
