I am having some high chlorine consumption, about 3ppm per day. I have been doing a SLAM for 3 days now, and the consumption is not going down. I am beginning to think it may be consumption for other reasons. To provide some background:
1) I had the pool reverse osmosis treated last week. The CYA was reduced from 300 ppm to 31 ppm. I don't think this is a cause, but mention it in case.
2) Our neighbor has two large trees which are covered in a whitish blossom much of which is falling at the moment. A lot of this is getting in the pool. On a windy day I estimate I had more than 1/2 a pound (dry weight) of blossoms fall into the pool. I don't know if these could be accounting for the high consumption.
3) Water temperature is around 54 degrees.
4) Water looks very clear
5) CC is small, less than 0.5 ppm.
Unfortunately the blossoms started to fall about the same time I had the RO treatment, so it is hard to separate causes.
Is it reasonable the blossoms are causing the high chlorine consumption?
