Numbers after 1st week of BBB

Apr 4, 2011

Here are my numbers after 8 days of the BBB:

FC=3.5
CC=.5
pH=7.6
TA=100
CH=130
CYA=60

Do I need to go ahead and add some calcium chloride to get the CH up or will it hurt to leave it as is?

Thanks to all who helped! This BBB is definately the way to go as far as I'm concerned!

By the way my water is almost crystal clear now after running the filter non-stop for the past 8 days.
 
Your CH level is just fine. Vinyl pools are fine with CH relatively low.

Your FC level is a little low. With CYA at 60 the normal day to day FC level should be 5 to 9. Otherwise your numbers look good.
 
Experiment with different target levels to find something that leaves FC above 5 the next day. The most appropriate target level will change as the weather changes and when more or less people are swimming in the pool.
