Usually we only deep clean at the end of the season. Providing they are working to their ability, Hosing off is fine during the season.did clean it like that last time, just didn’t know if I should add a cleaning chemical
Try it again and only quick glance. The brain plays tricks on you. Wanna see how ? Do you see your nose ? Yup. There it is. And now you’ll see it for the next 2 mins when it disappears again. So instant glance the cya tube. Move up 10 and try again. Call it when you can’t easily see the dot. You can also reuse the sample to test and go best 3 out of 5.I checked the CYA and I filled it to the top of the tube and although the dot is not black anymore if I really really look I can see it. Any advice?
