Which Apex A3 LLS probe is right for a 12 inch tall aquarium?

Hello my fellow reefers,
I recently got an Apex A3 and I want to buy the LLS however I don't know which size it's more suitable for a 12 inch tall tank, the 4" or the 15".
Thanks as always for the advice.

The LLS does not need to be vertical in the tank it can be placed at an angle. If you want to measure the water level above 4" and have the space to put the 15" in at an angle then I'd go that route.
