After a lot of pressure testing, dye testing, etc., I found that I've got water flowing into the electrical conduit in the back of one of my light niche's (wet niche, Pentair Intellibright LED light fixture). There is a bonding (ground) wire and the light cable running into the conduit from the...

Does anyone know how much chlorine is released from a hot tub as chlorine gas? Obviously, there are a number of variables here so we'll assume perfect water chemistry and FC level. Obviously, chlorine gas is 'suboptimal' for inhalation and I've always assumed (maybe incorrectly) that the level...

I've been reading up on the chemistry of the different chlorine compositions to determine what to use when I can't get liquid sodium hypochlorite (thanks ChemGeek) and ran across something odd: The link below is to a granular trichlor product - which sounds like the stuff people are using in...

From what I've gathered on this site, it seems the chlorine should only be decreased by sunlight and attacking organic materials in the water. So, if I have clean water and no sunlight, should my chlorine levels be stable (such that I should not have to add chlorine)? This question is...
