when if to culture water

[engrav]

Less than two years with a pool but it is in pretty good TFP shape.

If a pool is well circulated, sanitized and balanced, it must be unlikely that there will be harmful organisms in the water.

But is there ever a
1) time when or
2) reason why
one should culture the water?

Searched TFP for "culture" but did not find, nor with google.

Thank you

No point. Just maintain adequate FC for your CYA level and nothing can live in the water.

got it thank you

but say I get sloppy and for a day or two or three FC is too low
but water stays clear and I then get back up to speed

still then no need to worry?

Then you should follow the ShockLevelAndMAINTAIN Process ... or at least Perform the Overnight Chlorine Loss Test to see if anything is in the water.

ok
thanks

This has certainly been discussed a lot, but I'll bring it up again - OCLT's are generally not a very good diagnostic tool at Target FC levels.

The OCLT was conceived as a set diagnostic criteria to be checked during a SLAM. Those criteria do not necessarily make sense at Target FC levels.

That being said, failing OCLT at Target FC is probably not a good a sign of pool water health, but passing OCLT may or may not mean anything.

As for culturing your water, that just doesn't make sense for a whole bunch of reasons not least of which is sample control. It's very easy to contaminate a sample prior to spreading it on an agar plate for bacteria/algae growth.
