Swimmers in pool after swimming in pond

[jeffboer]

I have a few teenagers who are swimming in our pool today after swimming in a pond earlier today. Advice I’ve received in the past (not here) instructed me to not allow suits in the pool post pond/lake swimming unless suits had been washed to avoid algae. However, the kids wanted to swim, so I let them swim!

Following the TFP method, keeping my chlorine levels where they should be based on CYA, is this valid advice? Anything special I should do tonight? Maybe bump FC up a few PPM past the high end of recommended? Thanks for the advice!

Just maintain your FC level within the target for your CYA based on FC/CYA Levels. The FC will handle any algae coming in from the pond.

If I had a few teenagers in the pool I would bump the FC regardless.

Algae is ever present and is always invading your pool water. In a similar way weed seeds are always being introduced into your flower beds or garden.
If the conditions are right the algae or weeds will thrive. Our job is to keep the conditions adverse to biological invasion.

Like Allen said above, maintaining the FC level should keep you out or harms way. But, I will say, that there are more stubborn algae that can get introduced in this manner. So, it would be advised to not allow this practice.
