We decided to switch over from Baquacil to Chlorine this year when we opened (late May). The pool shop told us we needed to change the sand and they would handle the rest. The pool was foamy and yellow to start, then cloudy, then clear. We thought we were done, and started using the trichlor pucks and shocking once a week. The pool was clear, but always low on chlorine (1 or less unless we shocked). When the weather warmed up, we started to get a bit cloudy and started shocking more often. That was when I was told that we probably had algae ready to bloom and should start shocking at night to kill it off. Also I was told my CYA was high already and should stop using the pucks. I went several days, shocking to 15 -20 at night (temps were in the 95-105 so probably a wasted to try to keep it there). It would be down to half by morning and down to 0 by 10am. This is when I thought it could be the Baq. conversion. A sample sent to a local pools shop showed a Baq sanatiser level of 6, low but still there. I am on a full week of shocking it at night to 15 or higher. Been using a mix of 6% bleach ($2.50 for 182 oz), 10% from Rural King ($12 for 4 gallons) and Veratex ($17 for 4 gallons) from a pool shop in case the cheap Rural King stuff was low on Cl.
The pool is crystal clear, but not holding Cl levels. Any suggestions on how to proceed (temps are 95-over 100 every day, pool gets no shade). Any guess on how much more bleach I need to buy?
My guess on pool size is 17500 since it is a vinyl inground Grecian 17x31 3.5 ft deep on one end, 6 ft on the other Here are my latest readings used a ColorQ 7 drop meter (I hate sticks and don't trust myself to color match).
FC - 0.02
TC - 0.1
pH - 7.4
ALY - 202
CH - 248
CYA - 78
