Can anyone direct me to a good newbie thread?

Thanks. CYA added last night but showing up as 0 on test strip. Add more or wait?

wait, unless you backwashed your filter. If you backwash the filter before the CYA is dissolved (takes 3-5 days), then you've lost it and need to add more. If you don't backwash the filter, give it 4-5 days before you retest or add more.
