Tarek El Moussa and Christina Haack have their reasons for ending .«Christina is looking forward to working on new projects, and their own solo projects.

It was time to be done,» a source close to Haack tells ET. «The series is ending with great ratings. She is starting to film next week.»Another source tells ET that El Moussa and Haack have joint custody of their two kids, 11-year-old Taylor and 6-year-old Brayden, and work hard to co-parent successfully. «They communicate for the kids,» says the source. «Off set, they aren’t really friends.»On the  series finale, the former couple take on a «monster» pool that's better described as «a sink hole,» and the pressure of such a job leads El Moussa to walk off camera.

El Moussa, Haack and their trusted contractor, Jeff Lawrence, are all taken aback by the massive work in the backyard that features a gargantuan pool that clearly needs a ton of work and will prove to be expensive.

In a sneak peek of the final episode, dubbed «Spanish Lessons,» El Moussa initially guesses that fixing the pool alone will be $10,000 because it'll need to be re-plastered and re-tiled.Lawrence guesses that, because «this thing's a monster,» it'll be more in the $13,000 ballpark range.
