fertilizer - for greenwater - Local source?

[GregDoug]

I have made a careless mistake and ran out of Micro Algae Grow from FAF and now I need to find a fertilizer for my green water cultures very soon. Do any of you guys use a locally found fertilizer from a store like Walmart, Home Depot, Target, ect?

any aquarium plant fetilizer. get one high in iron. i've tried a few but have gone back to fafs mag. the added iron ferts work better. you gotta sacrifice some time and phyto, but it can be worth it.
my latest test was nutrifins plant grow. i started with the same dose as fafs micro algae grow. 1 drop per 100mls. it worked ok with dunaliella. i've been having crashes with nanno, although i could just be me.
i've thought about hydroponics ferts as an alternative.

Crashing nanno is hard... I'm leaning towards the use of a plant fert rather then a proper Guillard's F/2.
