Dosing is the easy part, it really depends on how
much light you have and what you're over all goal
PPS works for some I suppose and that is a personal
preference, the plants do not care how much nutrients
are in the water, as long as it is enough, the light is the
driving force and will determine growth rate as long as
the plants have food.
The goal either way you dose is to feed the plants.
No light=no growth
low light=slow growth
medium light=medium to fast growth
high light=fast growth
All this of course depending on the type of plants
The first post in this thread is a recommendation
on dosing for a highlight tank around 3wpg.
If you want to use less light just use less nutrients
hence the +/- before ea. nutrient amount.
PPS is the same thing with just a little more leg work
by mixing everything and then some and counting drops.
You can do the exact same thing dry dosing and it is easier.
I am all for the ease of maintaining a tank, I would rather
enjoy the tank/prune or play with the wife and kids/grandkids
than fiddle fart with counting ferts, which in reality is goofy.
Simply put the plants do not care so long as they have
food when the light is forced on them.
Whether you are dosing PPS=dose less more often or dry=scoop and toss
it is too simple, some PPS folk claim EI is excess and
cause problems, most of that is just user error.
You do not have to change 50% water every week
but it certainly does not hurt a thingy.
I have read of other folks dosing misery on both sides.
I have never tried PPS or felt the need, I have been
using this stickys dosing recommendation for years
any problem I ever had was my own stupidity or just
to busy to spend time with tanks which in turn taught
me to burn less light when I can't tend to my tanks,
