got..it.. make sure you are using a good tool to read the 1.009
Ya I think you are right. Looks like the Milwaukee is off a bit. With my hand held refracto im getting what looks like 1.007-1.008 going to raise it a hairi would suggest only using the hand helds Refractometers. the digital refractometers i had was off. was a good and expensive Milwaukee but not correct . My neptune was not accurate enough for this.. there are good to see any swings .. just my 2 cents.
There is somewhere here that talks about proper calibration of handhelds at the proper salinity.. please check on that.. and use only a good handheld. i had two and calibration solutions at 35 ppt. I think but please check DO NOT calibrate at 0.000 still calibrate at 35 ppt per solution.. again please check somewhere here on reef2reef it is discussed..
I need to raise the PH what is the best and fastest way ?
Humblefish when you are talking a small amount like what is small ? we are working with 300 gallon system volumeBaked baking soda: Spread baking soda onto a clean baking sheet, and bake at 300F for 1 hour. This process drives off water and carbon dioxide from the baking soda, and the result is an effective pH buffer. You will need to experiment (start with a very small amount) to determine how much is needed to raise your pH to the desired level.
take a table spoon to a glass of water and put in one shot glass size and see how it effects the ph. go very very slow. what is your current ph at?

Rodi for hypo, I'm fairly Randy Holmes Farley has confirmed this in other threads as well.I have and just did but i don't see anything about refractometers besides calibrate at 35 ppt solution. wouldn't you get better resolution going from 1.000 to 1.009 then you would from 1.026 to 1.009. I'm asking what is going to be more accurate Ro or 35 ppt solution
