The advice I’ve seen out there ranges from 2 Tbsp/gallon (which seems awfully high) to 1 Tbsp/5 gallons which is where I am now. There are also a lot of arguments that measuring salt in Tablespoons is useless b/c the effect on “salinity” depends on the grain size and type of salt (mine is about as fine as Kosher salt) and the only good way to measure it is with a hydrometer. However, hydrometer readings are affected by heat, so that needs to be calibrated, and even the recommended hydrometer readings seem to be pretty varied. I did buy a cheap one that starts at 0.000 and goes up in increments of 0.002, but that’s probably not sensitive enough. So what is your take on this? Can you set the record straight? I know salt levels can only be as high as your species of fish can tolerate, but there also must be a minimum level that has to be reached to be effective against Ich. <... a real answer would require some
