Can't vacumn to waste with a cartridge filter. I had to partially drain and refill my pool when they set up the SWG because they dumped in too much salt and my cell shut off with a high salt warning. I used a submersable aquarium pump (a very large one) and drained a foot below the skimmer. I then refilled and had to repeat this 3 times to get my salt levels in line. It is not necessary to drain all at once. You can drain a foot and refill until the CYA levels are where you want them.
