Not unless you have a concrete pool. If you do have a concrete pool or a SWCG (Salt Water Chlorine Generator), your TA (Alk) is too high.

Otherwise, it's not a problem, except that your pool will be 'twitchy' with respect to calcium and pH. If you add a shock dose of calcium hypochlorite, you might cloud your pool badly. Likewise, if there's much calcium in your pool, letting the pH go up a bit could result in a very cloudy pool.

You can lower the alkalinity pretty easily over time: http://www.poolsolutions.com/gd/lowe...p-by-step.html
