Might be algae ... follow the shock process and keep brushing and it should be gone (unless the pool is actually stained).

No more tablets!!! They add CYA and you are at the top of the recommended range. They will last for years, so you may be able to use them while on vacation or if your level drops due to backwashing and winter.
Basically, you are correct, Taylor does not take the CYA into account ... there are some weird legal reasons why companies never say more than 4ppm too. Government and pool companies seem to be VERY slow accepting the proven chemistry and change their ways.
