I know this is a stupid question, but I honestly looked all through the owners' manual and can't find the answer.... How do I take off the salt cell and open it to clean it out? Does it just unscrew off of the pipes then somehow pop open? (It's an AquaRite) Our indicator has been flashing low salt and inspect cell; indicator says 2600; strip test says 3100. (Am also going to head to the pool store to see what their testing shows.) Assuming I flush out the cell and am still getting a low reading, how can I reset so it will stop flashing? TIA
