if i wanted to buy a phosphate hanna checker would i buy the regular one or the new ultra low range one??? the REGULAR one measures 0.00-2.50ppm and the ultra low is 0-200ppb

Hanna is used for presice measurements that a test kit does not detect. I would get the regular unit, any levels above that spectrum should be easly picked up with your standard test kit

the regular one. no need to spend the extra cash
