We decided to deep clean the filter after reading and watching the video on here (thank you for that) We bought the house in August and by the looks of the cloudy grossness coming out of the filter looks like it was never done, old homeowner said he changed the sand 2 yrs prior to selling the house but who knows. Anywho... we found this little gadget as soon as we started ... it just floated up to the top once we disturbed the sand a little. Any idea what it is and is it essential for the workings of the filter??
Thank you
