I also use bioguard products and run pool for 4 hours a day at night.
One thing lacking from B...350's response was the high cc (combined chlorine), you're at 20%, so a nice shock dose of chlorine is in order - I'm supprised you can't smell the chloramines. Mwsmith2 has a calculator program that you can use for this, just search for any of his posts and you'll find the link. None of the other 'senior' members have posted here, so I also suggest that you go to the top post of the "using chlorine" topic and check out "Ben's Best Guess..." made re-available by Watermom - it deals with chlorine and shock levels, dependent upon your cya level.

Finally, and the real reason for this post, the tot alk and hardness levels you've posted, came out of some computer's programming logic and may at best, reflect the true values of your pool water. I'm fairly sure that Ben's explaination of this is to be found in the 'sister' site to this one, PoolSolutions, which I believe can be reached by clicking on the icon at the top of the main forum page. (It goes into a discussion of precission vs. validity in pool store testing - the numbers in question are usually given in multiples of 10, so when you see a T/A reading of 159, the red flag comes up). On the same site I believe Ben takes a little skin off of Biolab and their product sellers ( FYI Ben is Pooldoc, the owner and creator of this site - we all defer to him).
I can give you a decent synopsis of the info I've directed you to, but I think it's best for you to read it yourself, that and my notes are a mess right now
I doubt you are in any serious danger right now, but the more you know, the better you can take care of your pool and make better, and better informed, decisions reguarding your pool in the future. I strongly advise reading the entire POOLSOLUTIONS site, asap!
