Here is the datasheet for your battery:

Study that to give yourself a good understanding of how to use your battery.
Then you can make an informed decision on which charge profile you want to select.
I think you'll then agree that one of the "Victron Gel" profiles fits your needs.
Additional resources still need to be added for this topic
