You really shouldn't be blowing hoses on a regular basis. Have the dealer check the system relief and the individual spool valve reliefs to make sure they are set correctly. Make sure your new replacement hoses are at least 4000 psi 2-wire hoses.

Fluid level in the tank will depend on many things, first and foremost the current position of the cylinders. With all cylinders retracted the tank will be at its fullest since they hold less fluid retracted than extended. If you have to continuously add fluid than you have a leak somewhere, either internally or externally.

check your engine oil. If your hydraulic pump shaft seal is leaking it will allow the hydraulic fluid into the engine oil sump. this is not a good thing for your engine.
