TA that high will help precipitate iron out of water (if it's there) and cause staining. It will also help cause a pool with high calcium levels become milky and impossible to clear up. It also will make pH VERY hard, if not impossible, to adjust. Think of the issues that would happen if, say, his pH were low and he had to add several boxes of Borax to get it raised--that much Borax causes other issues with cloudy water all by itself.

If I'm not mistaken, TA levels also can contribute to scaling problems in high calcium pools, especially those with SWGs.

It needs to come down!!
