Sounds good! Does the fact that you pulled the injected CO2 from the 75 mean you are no longer dosing CO2 in that tank? Or am i misunderstanding?
I definitely agree that it is really fun to see before and after pictures, I look forward to seeing them for this tank once you get the rest of your equipment together, or rather once it comes i!
It does look to me like you have more of a 'red' than a 'bronze' crypt forest in there, crypts grow really well for me too! Do you know what the K rating on that light is? I have some crypts that are supposed to be red, and looked quite red in the store, but once I got them in my tank, the really washed out so I'm wondering what K rating you are using, I'm thinking that is my problem. They look beautiful and healthy, I might have to keep my eye on the SnS for some as a red/bronze comparison
