  1. I'm not new to working with a hot tub, but I'm running into issues that I can't get my head around. Background....400 gal. outdoor hot tub (hotel), bromine sanitizer, 250 lb. sand filter. Lately, our hot tub has been green-ish, which to me is a sign of lower bromine, but the levels have been good. In fact all the levels have been on the low side of good. The water color is a greenish-yellow, but very clear. In past weeks we have drained the tub and started from scratch, with similar results. The only thing I haven't done is change the sand in the filter, but that was done not that long ago. Also, what is the role of calcium hardness in the chemistry end of things? The levels for that never rise to where it should when we add the proportionate anount of CH increaser. These are probably noob-ish questions, but any help would be appreciated.
  2. Hi there. I'm the maintenance supervisor at a hotel, and we are planning on changing from chlorine to bromine. Little backstory.... Years ago we used stabilized chlorine, but found it difficult to maintain a stable Cl level without the CYA shooting through the roof. Then we switched to an unstabilized chlorine and added a CYA conditioner, so the maintenance of that was easier. Problem was that the chlorine tablets we got were very fast dissolving, and we need to add chlorine to our inline chlorinator a couple times a day to maintain a good level. Side note, we tried adding a bunch of tablets to the chlorinator with the hope of tempering the level using the valve control, but our Cl levels were off the chart. In the very near future, we are planning on switching to bromine. I was told by our supplier that we do not have to worry about adding and CYA conditioner to the tub while using this. True or no?
