3 piece shower and tub combo

I have a fiberglass 3 piece shower and tub combo and have problem with the bottom seam of shower where it meets tub. It always has like black gunk or mold in seam.I clean it all and then it always shows up again. was wondering if caulking this seam would help?

Sure, but please use the shower and tub caulk, siliconized latex with microban, not silicon!

I would also spray it with a bleach solution a couple times to try and kill as much as you can before calking.
Then dry it with a hair dryer.

If you caulk you should caulk all the seams. You don't want water to get between the panels at one of the vertical seams and have the water trapped at the bottom by caulking the horizontal seam.

Was ready to caulk all seams and someone told me that the shower will cause condensation behind shower walls and cause problems so im confused.

Condensation is not going to be a problem, or water, because you will caulk, the un-caulked state has higher potential to allow water to get behind panels!

Yes condensation will not be a problem.
It only happens when warm moist air meets a colder surface so unless you like taking cold showers it cannot happen even then it is highly unlikely.

You may want to practice your calking technique before starting.
You want the smallest bead that will do the job when calking bigger is not better.
Perhaps take a look for a couple videos on-line to find a technique that work for you.
