Pool Trouble

The house we live in, (are renting until we can buy), has an in-ground pool.  I have ALWAYS wanted to have a pool of my very own.  I was SO excited to move to Florida and FINALLY have my own pool!!  The kids, of course, loved the pool too, at first.  It seems familiarity breeds contempt as far as pools are concerned.  I lost my love for the pool the first time there was a major problem.  This pool is, as far as pools in Florida go, old.  That means that bad things are constantly happening.  Holes in the liner, pipes cracking, impellers breaking... and every time something happens, the water gets yucky.  The last thing that broke was the impeller, which meant there was no water being sucked through he filtration system.  The water got SUPER yucky in the time it took us to figure out what the problem was, and get around to fixing it.  The entire pool was covered in green slime.  It's amazing what happens to stagnant water.  We finally fixed it this past weekend.  There is nothing more satisfying than fixing a problem!!  I was SOOOO happy when we turned the pump on, and it started to make the familiar noise of priming!  And the first water that was sucked into the system made me do the happy dance all over the back yard!  :-D
It took less time to replace the impeller than it did to get the green slime out of the pool, but it's all done now, and the pool is sparkly and clean, (and freezing cold, so it doesn't matter if it's clean or not, nobody will be in it until at least April).  There's just one thing that concerns me.  After the pump ran for a couple of hours, I turned it off to empty out the baskets before back washing the system, and there were live earth worms in the basket by the filter.   I've noticed that the system is sucking a little air with the water, and there's a slow water leak.  There are more air bubbles than normal coming out of the jets, and the water level goes down a little faster than normal evaporation.  I have a sinking feeling that there is a crack in one of the underground pipes.  *sigh*  That means much expense, and digging.  I'm not looking forward to that problem getting bad enough to need fixing.  I'm not going to lie, I really do think that this pool is more trouble than it's worth.
