My dad wants to setup a planted tank, thing is though he's a total noob (only at plants). He needs easy, uncomplicated ferts. Preferably something that is all-in-one, but seperate ferts are OK. Definately nothing that has a high risk of creating algae blooms. Iron is a must since the water treatment plant has removed it all. I think the phospates are rather high so won't be needed. The water is very hard so it has plenty of Mg. - will post accurate results of the parameters in a few days.
The key here is EASY. Something that won't discourage him out of the hobby and cause complications.
I feel I left out some critical info, let me know if you need more.
