Pfertz

You somewhat contradict yourself.. Concentration isnt important but providing enough nutrients is the key..

Both are important

If 5mls of say flourish contains 3% iron and 5mls of some other fert contains 5% of iron.. Then concentration matters and you would have to dose more/less of one of the ferts to come to a desired ppm.

I'm dizzy - again, my point exactly!
 
sorry didnt finish yet.. lol

Also if you notice each manufacturer has their way of dosing. So if seachem says dose 5mls every day of this (3%) and another one say their amount.. in the end you will end up with different concentrations in the tank. Can be good/can be bad. From cfsin's view its GREAT since the tank looks so great and balanced out (knock on wood)
 
Didn't combine - remember I went to the SeaChem chart you sent over - that's when the trouble (and plot to sabotage my tank) began. Stopped SeaChem and started Pfertz - the ultimate in Aquarium Fertilization!!!! I think the real mental picture here is you looking at your tank and visualizing mine (lol)!!
