That is a lot of light to have over a 29 gallon tank without CO2
. You may want to try and setup a DIY system of (2) or (3) 2 liter bottles.
Your lights should be on a timer set for a period of 8 to 10 hours.
Stuff your tank full of plants.
What ferts are you dosing?
Edit: After going through your tank log, I see you would have to make some major changes to go the CO2
route. You have a lot of surface agitation going on.
