I was about to order dry powder ferts, but then started to wonder what the advantage is (if any) over using TPN+.
I've read that TPN+ may be a little light on potassium phosphate.
I'm not sure now whether I should go down the basic EI (dry ferts) route or TPN+ supplemented by Potassium Phosphate.
The tank I'm setting up is my first 'hi-tech' planted tank and is 300litres.
Which should I go for, and why?
Thanks
