Hi everyone. I am new to TFP but am quickly being converted to the BBB Method. I have a 16' x 32' ABG Doughboy pool that is 54" deep and buried 2', with a sand filter. We have been getting 0 FC readings since opening about a month ago. After numerous trips to the pool store and lots of shock (powder) nothing helped. After finding your forum I started adding liquid bleach over 2 days. First day, 5 182 oz bottles - no change. Next day (Saturday night) 10 182 oz bottles added slowly in front of the return. Within an hour the reading using an OTO kit was dark orange, same reading the next morning and again this morning. The water is clear and has been all along. Is it safe to swim? If not, how do I lower the FC level? I have 3" pucks in a floater, is this still necessary? My levels at the time I first added the bleach are as follows:
TC - 0.6
FC - 0
TA - 161
ph - 6.9
CYA - 40
TDS - 300 (not sure what this is)
I plan on taking another sample to the pool store today. I have ordered a testing kit from TF test kits. Hopefully, I will soon be able to figure all of this out myself. Thanks for hosting this site, it is invaluable.
