CYA Testing

[mikech]

May be a stupid question (and probably is), but would it be possible to develop a more accurate CYA measurement test based on capillary action of the turbidity solution created by the Taylor/TF-100 kits? My (ignorant) thinking is that the more turbid the solution, i.e. higher CYA, then lower the capillary action? If so, then it wouldn't be too difficult to develop a graduated set of capillary tubes, would it? Before I go out and buy some tubes to test I thought I'd run the base presumption past the gurus here first.

I'm not really an expert on capillary action, but my guess would be that it would be difficult to get consistent results given variations in cleaning of the tubes between uses and differences in surface tension at different borate levels.

don't mean to hijack this thread but, I have a question about CYA testing Jason. My pool water was at 67 and didn't realize till after testing CYA. it came in at about 100. What affect would the lower temp cause, higher or lower reading

 

[mikech]

My experience has been lower at lower temps

thanks mikech, I had better retest
