Re: Profile hardens water

>>>In my Profile only tank, the plants do not grow as fast as in my tank
with 2"
soil covered by 1.5" Profile substrate - I think you would definitely
need to
add supplemental nutrients to a Profile only substrate if you have
lighting and CO2 supplementation; and I would not use it in a soft water

kind regards,

Susi - my data shows that rinsing Profile thoroughly removesn the
leaching of substances into the water column.  With enough rinsing you
can use it in soft water tanks.
