Hi all,

Right now i have the Seachem products and dosing as recommended in their website but the costs are ultra high for a 450 litre tank. So I was browsing the net and found EI and PPS - Pro. I cannot do 50% WC weekly I only do 25% so I have to forget EI. So next one is the PPS Pro. Before this can I make something similar to Seachem products via dry ferts?

If not then for PPS - Pro is it really cheap? Will the plants suffer from any deficiencies? If yes can I add more ferts? Do i add more dosage daily or should i add more ferts to the current mix?

My current set up is

450 litre tank
Seachem Flourite gravel
216W T5's on for 10 hours daily I also have reflectors on them.
CO2 via ph controller set to 30 ppm
