I'm very new to the planted aquarium but am going to give it a shot. It appears I need to get a good substrate. So I'm going to purchase Eco Complete Plant substrate. It comes in 20 lbs bags (How much do I need for a 20g H aquarium?).
It is a completely cycled set up w/ 6 tetras, 2 albino corys, 1 danio, and 1 pleco. Should I move them all to the 55 gal while I get the plant thing going?
Do I drain most of the water out to put the substrate in? My plants are already ordered and will be shipped April 1st. How long can they wait in their shipping packaging before I put them in the tank while I get it ready?

I know I should've waited until all things were set up before ordering the plants but I didn't and they are on their way.
Thanks,
