Hi folks,
I'm in the process of setting up a new tank (125 Gal, fresh, planted),
and was wondering if hiogh iron levels will be a problem. The current
level
is .640 mg/L (yes thats not a typo). Ph is 7.8, and hardness is 59
(Calcium
carbonate). The only thing that seems out of whack is the iron... I have a
water softener (ionic collumn) that brings the iron levels way down, so I
*could* just use the softened water, but its a lot easier (plumbing wise)
to
use the untreated water......

Any suggestions?

You could use aquarium plants that need an iron rich environment (Amazon
swords for instance), although I am not sure if it the type they can utilise
for growth. I always use a high iron content fertiliser to keep them a lush
green. Alternatively you could use polyfilters, but that would work out
expensive.

Regards

Mark
