Having to backwash hours after opening?

[Vukota12]

Hi. Opened today to some organic material that blew under cover over winter not too terrible and some cloudy water but not green. Filter cleaned DE added , chems added. Spill over spa flow was going strong for a few hours and then slowed like it does when it’s time backwash with the PSI on gauge up to 18 after staring at 12. Could I have to backwash this quickly?

Classic sign of algae in the water clogging your filter.

You can do an Overnight Chlorine Loss Test or skip right to the SLAM Process

A pic of what it looked like when the cover came off. And then a few hours later. Could it be Pollen quickly clogging the DE filter? It was very very windy today with pollen flying everywhere.

Possible. Do the Overnight Chlorine Loss Test...Link-->Overnight Chlorine Loss Test
If you fail, you SLAM. Link-->SLAM Process
You pass, it's pollen.

Not pollen.

Do the Overnight Chlorine Loss Test

Got it thanks. Going to do the OCLT test and see where I am at in the morning. Is it ok to run the filter all night with the slower flow?

Yes.

Get the FC between 3 and 10 after sunset and then test before sunrise.

Almost 4 PPM after sunset going to test early AM. My CYA was between 40-50 I hate the black dot at the bottom of the tube. Not conducive to my 70 year old eyes.

Sunset isn't unti 8pm. Do test after sunset and before sunrise, 5:50.

Sunset is 7:55 pm in NJ today.

Sunrise is 5:49 am in NJ tomorrow.

We round up. Call it 50 and move on.

Was very cloudy when I tested.

Was very cloudy when I tested.

AFTER sunset, BEFORE sunrise. Cloudy or not, there is UV. We are trying to take UV out of the equation.

Was a touch over 3 PPM after Dark and was a touch under 2 PPM at 8:15 AM. I think I passed the OCLT test.

Sounds like you lost over 1ppm, which is a fail. I'd personally consider a 1 as a fail, especially at opening.

From 3ppm losing 1ppm is a fail.
