Filbert's Day at the Pool

I am worried that we do not receive enough sunlight on our balcony. Filbert was looking a little droopy this morning and I couldn't just leave him in the shade for the whole day. Therefore, I decided to bring him to the pool. As soon as I set him down I could notice a difference in him. His leaves became brighter and he stood a little taller. I have a feeling I am going to have to do this more often. Any suggestions on how I can keep him alive without much shade???
