I am about to 'have a play' with my nutrient levels and increase the level of iron to see if this helps out my plants (am thinking in particular of my swords). I am happy with my method for doing this (I'll be using the EI approach, nicely explained by the man himself Mr Barr in this post here: viewtopic.php?f=11&t=1648&p=17202&hilit=iron#p17358 ).
My next step is sourcing the cheapest iron powder that is safe for the tank. So I am searching via the usual suspects; AE, ebay, garden direct, etc.
I don't feel lost as such within the choices available (although the wikipedia article on iron left me none the wiser ). I am more curious to see if there is any words of wisdom proferred from the gurus on here
This looks like a safe form: "Ferrous Sulphate (Iron II sulphate) hepyahydrate, FeSO4.7H2O, Technical grade 99%" and is near enough the same price with postage via an ebay seller as it is on AE without postage. ( http://cgi.ebay.co.uk/Ferrous-Sulphate- ... 286.c0.m14 )
The following is is a fantastic price (and wil last a long time, if not forever!), but is probably too good to be true, so I have asked the seller for more info:
http://cgi.ebay.co.uk/ASG-SULPHATE-OF-I ... .m20.l1116
Garden direct have no fewer than 5 different types of iron If anybody wants to shed light on there varying degrees of suitability I'll happily read the replies :
