Cowboycasey, that's pretty close. I can raise the dose levels, or raise the CYA level to slow the loss rate (with lower chlorine dose levels). Daily measurements and trends are important while we get this dialed in. Here is an excerpt from a chem geek article that was referenced by the link...

Hmm, answer may be in this article (forgot that Google is my friend!). Anyways, I'll read it in detail later (not sure I'll understand everything, but will read it!). http://www.troublefreepool.com/threads/83437-Picking-the-most-economical-CYA-level

Hi Phibroptic! That may be a valid assumption, but I hope it's wrong :-). Hopefully, the brains of TFP can help guide us!

Thanks Patrick_B! I failed to ask if there is any experience/chemistry knowledge that people can share regarding the different loss rates. Is it somewhat directly correlated? For example: would a doubling of CYA reduce loss rate by 1/2? Or is it more pronounced (a doubling of CYA would reduce...

Hello All, We are about to complete a nearly complete drain to reduce CYA. Yes, we were doing all the wrong things - using pucks! Anyways, I'm hoping to start off with a CYA in the very low end of the recommended 30-50 range. Once we get pool refilled, pH and FC adjusted for the CYA we have...

Hello All, I haven't forgotten about this. So, an update: After discussing with owner (girlfriend), I disconnected power to this particular light fixture. Something I do remain a little confused on, so thought I'd ask: how is a leak coming in back that manifests itself as pooling water in...

Divin Dave and bdavis, I hear what you are saying. I also don't think relying on GFI as my safety net is a good idea. But, preventing water from entering the housing is my goal here - so GFI won't trip. [edit: if I can't get signs of a leak to stop (water entering housing), I'll disconnect...

Background: I've been maintaining my girlfriend's pool and have changed the bulb/gasket on one of her pool lights multiple times. Each time, the end result was the same - water eventually leaked into the housing and GFI did it's job. I have always assumed it was my inability to get a good seal...
