If I am not mistaken Mr. Fenner recanted his thoughts on lower sg and revised the statement in his newer edition. The reason lfs' use a lower sg is to save on salt (less money spent) and, in theory, reduce parasite %'s; however, unless they are using a hyposaline concentration then the parasite (Cryptocaryon/ich) can still live and reproduce. As far as the Alkalinity reading, am I wrong is assuming 4.0 is in meq/l? If so then that is fine since I do not see 4dKH as possible without having a bad batch of salt.

Good point about the alkalinity... I got to remember there are so many ways to measure the same thing.

Thanks guys.....some very valid points i.e. the best long term results would be obtained by creating an environment as close as possible to nature. Point taken. Yes measured with a calibrated refractometer. We had 1.018 prior to water change (20%) and brought it up to 1.019 post. Do you see any problem raising it .001 per water change (every two weeks)?

Speaking of water does everybody use RO/DI water?

Thanks...keep the advice comming!

I know I do. What are you using? Also you dont have to wait till PWC`s to increase salinity. You can also add SW instead of FW during your top offs. that will raise your salinity. Maybe add a few gallons of SW every three days. I believe you said you have a 180 gallon tank.
