Every once in a while I have to raise or lower the salinity of my DT. It is a 200G total volume system. Is there a calculator or formula to tell me what my salinity needs to be for a specific amount of water?
For example, for a 200G DT, the SG is at 1.024 and I want to bring it up to 1.025 with a 20G water change. What is the SG of the 20G that is needed to bring it to 1.025?
On the reverse, if I want to go from 1.026 to 1.025 on the same system with a 20G WC, what is the SG of the 20G needed to lower it to 1.025?
I have tried winging it, but I end up adding RODI to the DT to lower or sometimes adding salt (small amounts) directly to the DT to raise the SG. I know there are calculators out there to tell you how much salt to add DIRECTLY to your DT, but I don't want to do that. I would rather do a WC where the salt gases have dissipated.
Thanks
