Vacation

[joemkraus]

If I typically lose 4ppm per day of FC with my recommended range of 5-7, and before I go on a 3 day vacation Take it to 16, will I still lose only 4ppm per day so on return I would still have 4ppm, or does it deplete faster at higher levels?

My experience is that going much above your FC target zone for your CYA will increase your daily FC loss.
Can you float a few trichlor pucks? What is your CYA level?

 

[joemkraus]

CYA is 40, and yes floating tabs this time as well as took it to slam levels, just wondering if I needed to float the tabs next time

Next time? If several months from how then daily FC loss will diminish as we move into fall and winter. You may also see some degradation of your CYA levels over time and tabs are still OK. If you are only gone a few days just pull the tabs out when you get back. If your CYA gets to 50 you may want to find someone to dose your pool with liquid or Cal-Hypo (check CH level) for you rather than use trichlor tabs or dichlor.

Thanks, never used Cal Hypo and have no experience, my calcium level is pretty low so I understand that is the only downside but in my case I guess It’s not gonna be a problem. No problem with using it with liquid chlorine? Do they make Cal hypo tablets?

We use these for drip line sanitation, no experience in my pool though. Food Safety & Irrigation Applications - Accutab

It appears they have different formulations and do list pools so do your research or contact a representative for more info.
They are 65% Cal-Hypo tabs...... Aquatics - Accutab
It appears they are colored blue but I do not see any copper in their MSDS.
