Question about ferts
Hi, I have a 70 G planted tank, with a substrat that's clay and a bit of earthworm humus, capped by gravel.
I dose once in a while whatever liquid fertilizer i could find here in Venezuela, most Hagen, which most people have told me it's crap.
A few weeks ago i found Sera Florena. I also dose Seachem Excel.
The plants i have are: Vallisneria, Limnophila sessiliflora, Higrophylla difformis, H. polysperma, S.subulata, M.pteropus, Cryptocorine species. and Rotala rotundifolia.
They do ok, my lighting is 2 T 12 tubes, 40 watts each. 2 T8 tubes, 32 watts each, and 2 compact flourescent each one is 20 watts.
So i guess i am around 2.5 wpg.
Anyways, today i found and inmediatly bought a bottle of Seachem Iron. They also have Potassium...
Should i get Potassium as well??
Will my plants do ok with only Fe iron? I know the ideal would be to have them all, but if you could only get one, which one will you choose??
