Which is why I suggested increasing your SG up to 1.025, it's part of your problem but not the main issue. IO salts are still Ca deficient. If you had a refractometer I would have suggested 35 ppt (1.027 SG) which is NSW and where most salts are made to work best. Many salts are "designed" if you will to work differently at a given salinity. Increasing the salinity will increase the chem along with it. One reason I urged you to do the same with the main (via water changes) in order to make this a bit easier.awillemd1 said:Could my entire problem here be that either I have been targeting too low of a S.G. and/or my hydrometer is reading too high? The IO folks recommended targeting 1.026 or 1.027.
If using SW at lower than recommeneded concentrations, your water changes will eventually bring the tanks chemistry in line with that of the saltmix depending on amount/frequencey changed. If in conjunction with dosing, you an easily end up with skewed numbers.
As far as the accuracey of your hydrometer, soak it overnight in a 10:1 water/vinegar solution, rinse in hot water the next day and let air dry. Retest and see if that was part of the problem. One reason to always suggest 1.025 when dealing with hydrometers is their inaccuracey is pretty much a given, especially if the unit is seen some use. With a refractometer you simpley need target 35 ppt and be done with it.
