Hi All!
I am starting my very first freshwater fish tank!

It's going to be a 54 gallon planted corner tank.
I've done some research and figured out what I would need for the tank. I just recently purchased a lot of things and I want to make sure that I have everything I will need. Also, if I bought extra stuff that I don't need, I'd like to return it. Here's the list of what I've already purchased:
Necessities
1x 54 Gallon Corner Aquarium (with hood and cabinet stand)
1x Eheim AEH2213370 Classic 250 Canister Filter 2213
1x Aqueon 06107 Pro Submersible Heater (150-watt)
1x 30" T5HO 2x54W ballast (haven't bought yet but plan to do so today)
1x Aqueon Siphon - 50 feet
1x Marina Floating Thermometer with Suction Cup
4x CaribSea Eco-Complete 20lb Planted Aquarium Substrate - Black
Chemicals
1x API Freshwater Master Test Kit
1x Seachem Flourish Excel 500ml
1x Seachem Flourish 500ml
1x Seachem Prime 500ml
Extras
1x Eheim AEH3581090 Automatic Fish Feeder
1x Fluval Flora SS Planting Tongs - 10.63in.
1x Fluval Flora SS Aquatic Plant Scissors - 9.8in.
1x Tetra 77854 Whisper Air Pump, 60-gallon (Plus air tubes and 1-in cylinder air stones)
Let me know if I've done anything wrong thus far! I'm looking to have a mid-high lighting tank so let me know if my lighting choice is no good. I found lighting to be VERY confusing so I may have not chosen a good ballast (hence, I haven't bought it yet).
Thanks!
