i gave you the best info in your thread for it, just go re-read that =) i will add here that for those that wet skim usually have a bigger tank and pull more out but having the bigger tank it will not cause the salinity to spike. having a small tank like miz has if she wet skims then she has the potential of pulling a lot of saltwater out with the wet skimming and then making it up with top off water will cause the salinity to drop over the next week or two and if it is not carefully monitored it could lead to a disaster that is why most people with smaller tanks dry skim.
