I've been using Flourish K and N for about a year, they are both great
products however as many others have done, now that my supplies are
running out I'm mixing my own to save some $. The PMDD article is
aimed at reducing algae, while limiting phosphates will work, it will
also limit the growth of your plants. Phosphate does not = algae in my
opinion, a balanced nutrient load and good plant growth will fix many
algae problems. If you have a high light tank with CO2 then you
shouldn't have any problems keeping a PO4 level of 0.2-0.5ppm in the
water colum (as long as nothing else runs out such as NO3,
traces....), if you have a slower growing tank it's sometimes best to
keep phosphates in the substrate, if this is the case, Flourish Tabs
are rich in phosphates.

You can compare the contents of Flourish, Trace and Tabs he

Sometimes I with Seachem had chosen better names for Flourish and
Trace, they can be very misleading. Flourish Trace and Flourish Trace
Supplement would have been better titles IMO

Hope that helps

I've tested my tank and nitrate and phosphate are almost
imeasurable.Plant growth is just not what I'd like so I've decided
to dose those two compounds.I can't find any greenlight stump
remover so I'm going to try Seachem's new nitrate and phosphate
additives. Has anybody tried these yet?
