A recent conversation with the owner of a pristine in ground pool that was the host of a 4th of July cookout and a few tips about pool and filter care. During the conversation he mentioned filter cleaning and rather than applying silicone lube to the O ring to kneed plumbers putty lightly within the filters cavity where the O ring would be secured. Explaining that an amount of silicone lube compressed to within the area inside the filter would have an affect on the filters wands the same as suntanning lotions would over time to block the wands correct flow of water thus resulting in high pressure and the low water output. Is the composite material of the plumbers putty less likely to block the wands in comparison to silicone and avoid a muriatic acid dip? Had to ask since I've used plumbers putty more often and it's less expensive and easier to get at a hardware store than silicone lube.
Also on that note I did find a safer acid recommended for adjusting pool/spa water chemistry and cleaning known as Acid Magic. Safer on the environment. A pdf file is available online.
