You shouldn't use 'distilled water' to calibrate your refractometer. You should be using the 35 calibration fluid to make sure. BTW - the Salinity is a difference of 1.024 and 1.026. I do not think that this is significant (given the margin of error when looking at a refractometer)Nothing wrong with PAR. Got a hold of an Apogee and spent 2 hours mapping the tank out across various intensities and depths. Its at 80-100 on the sandbed, 180 - 200 in the mid to higher areas. (This is with the light at a fairly low intensity).
Lots to think about here. Ill continue to address the Ca+, fix the salinity, and change my DIY Two Part to the BRS products.
The salinity is frustrating because Ive used distilled water ever since day 1 to make sure my refractometer measures a true zero. Maybe Im missing something. I may just grab a new refractometer.
@Randy Holmes-Farley how do you feel about that silicon in the RODI water? Its high in the RODI, but the tank seems to be handling it fine? I know there are suggestions to replace the DI unit, but only 1/3 of it has changed color and I'd had to be wasteful in getting another unit if I don't need it?
Really appreciate the input guys, I know its a lot to read through, but the experience I've had with this reef is nothing like I've had before. Definitely struggling to find the enjoyment.
