Good morning, we built out pool in 2001 and started it Jan. 31 2002. Subscribed and followed Ben Powell for years and now have the Taylor Drop test kit.
12,500 gallon gunite/plaster pool, Zeobrite in sand filter, Watermaid saltwater chlorinator on itís second cell running at 5,000 ppm
Due to the impending drought water restrictions I pulled back the safety cover back in March. There was the usual layer of dirt and I knew my hardness was over 600ppm. Drained and refilled with 5500 gallons soft water to bring hardness down under 300ppm. On April 15th started pump and noticed light green water in skimmer, hit hard with bleach to 10 ppm. and added acid to bring pH back down under 7.5.
Removed cover Sunday to find cloudy water! Could see dirt on steps. Brush and Bleach back up to 10ppm, CYA 30-40 so added 2lbs I had on hand to a nylon grain bag in skimmer. Ran Filter and Polaris all day, Filter pressure rose from 10 to 20 as is normal and backwashed twice Sunday so I think my media is ok. Have run filter pump continuously for 42 hours, no dirt on the steps I can see and pressure is holding at 12psi Chlorine consumption has dropped but adding bleach to maintain 10ppm +. pH 7.2, Baking Soda to TA of 60. Water still to cloudy to see drain 6í down.
I have never done the salt regen to the Zeobrite as we run a high salt concentration. But I have never used a media cleaner either. Have to go to pool store for CYA and replacement Taylor reagents so thinking the filter cleaner canít hurt. Have never used any kind of flock/clarifying agent and hate to give any more money to pool store than absolutely necessary. Still have to replace salt, but need that reagent as well.
So does Zeobrite ever wear out? Do I need a clarifer?
