[Lighting]

Hello

I have a 120 gal tank, 24x24x48. It is a newer planted tank with 2-48” aquarium co-op lights. Do I have enough lighting or do I need a third light fixture? I do not see any oxygen bubbles being created from the plants  in the tank. I am not using co2 currently but will in the near future. 
Thanks,

Eric

[Can you identify this plant]

Hello:

Can someone identify this plant. I want to make sure I don't repurchase.

Thank you,

[Advice needed on filtration]

Thank you everyone for your feedback on my question. I should have been more specific concerning the tank.  The tank is 48x24x24. It will be planted with moderate amount of community fish, tetras, guppies etc. i appreciate all the different ideas that was provided. I have a lot to think about it. 

[Advice needed on filtration]

Hello

I am in the process of purchasing everything for a brand new 120 gal tank. I was going to use one large  co-op sponge filter and the remaining filtration would be a tidal hob filter. Should I go with 2 tidal 75 or 1  tidal 110 or something totally different? Any advice would be appreciated. 
thank you and thanks for reading my post
