Did test at 9pm FC .3,CC .5?, pH 8+, TA 250, CH 150, CYA 35, Salt 3330, air temp 95, water 86
Added 55oz MA, then 56oz 6% bleach, then hung sock on skimmer with 28 oz stabilizer
at 2 am tested FC 26, pH 7.0, TA 200 Left filter running all night (what was left.)
Tested again at 6:30 am FC 30 Ph 7.0, TA 200, CYA 50, Salt 2780, air temp 69, water 82
Left sand filter running all day, SWG off, tried to aerate ( finally about 6pm got that going good)
Questions:1. How long do I continue to aerate? [IMG]splash.url[/IMG]2. When should I test FC, pH, and TA again? 3.and will my southern engineering of stupid Intex skimmer cause problems? I tied a 5 lb weight to it with trot line.[IMG]weight.url[/IMG] I was tired of purging the filter, also know I can't backwash for a week.
