I live in Florida and have a gunite and Diamond Brite pool built in 2004. I leave the pump run year round and brush regularly in the summer.
This winter it didn't get brushed for 2 months in Jan and Feb and I didn't add any chemicals due to the cold weather.
It was starting to show some yellow in March when the weather turned nice so I added some chlorine and proceeded to brush. I noticed a cloud of white was forming and some tiny pebbles/plaster that didn't float. I managed to coax everything down to the main drain and let the pump run all day. It looked pretty good until I checked it the next day and noticed the pebbles/tiny plaster pieces forming little piles in a couple places again. I grabbed the nylon brush again and the white cloud is back. Just like I never brushed in the first place. This has happened for 3 days in a row. I checked the chemistry and the ph is a little high and the alk is a little low. The hardness has always been high.
I will balance the alk tomorrow but I have a couple questions:
1. Do I need to just keep brushing and brushing until this stops?
2. Will brushing these particles that don't float down the main drain hurt the pump and /or plumbing?
3. Will I need a re-plaster? Like this year?
4. Did my neglect of the chemicals and no brushing cause this?
