Re: Underwhelmed by Bio-Active CYA reducer
Howdy all -
Registered here just because of this - and a related - thread on this stuff. Thought I'd just chip in here with another "underwhelmed" vote.
I work with a commercial pool support outfit here in the Phx area - hotels/apts/resorts. Obviously (?) CYA is an even bigger concern in the commercial side of things, the county doesn't come into your back yard and shut you down if levels get too high. And the politics between maint staff, managers, and residents in these places can make even suggesting draining a nightmare. So we've tried other products in the past, never any real success.
When B-A became available at our local wholesaler we made arrangements with a couple of our clients to use their pool as test beds. Both around 30-35k, one with CYA around 100-120, one MUCH higher. Both places we used dilution to get "seeable" numbers. Followed the label regard chlor levels and such (bear in mind that commercial pools run 24/7 per code). Tracked each pool daily for the 10 days, kept a running log on both.
Bottom line - after a "kinda-sorta" drop (10-20ppm-ish) in the first couple days - nada. No appreciable drop in CYA levels.
Shame - particularly in the commercial side, we NEED something that works - and works aggressively, at reasonable cost. For the moment, tho, it appears to be status quo.
