Welcome to our forum.
If this has been brought up before I apologize but I couldn't find it. When you adjust your TDS and calcium up do you shoot for the minimum or maximums? I checked with out local water department and both (tds and calcium) are way below the minimums. 56 and 40 respectively.If we do shoot for one of the extremes will it effect how other chemicals will react? I saw where high or low TA will effect pH and its adjustment. (I think that's what it said :-?)
I read that TDS, calcium and metals were to be tested for. When you filled your tub each should be in their particular range or adjusted to be within that range.From what you guys are telling me, don't sweat the TDS until it reaches 1500 ppm then do a water change. But to avoid foaming get the calcium in range or over 100 but less than 250 ppm. Right? :-/ Is there a home testing kit for TDS? My Taylor doesn't have one. Is that something you have to rely on from you spa dealer? Are there signs that TDS is high?I had also read that you don't adjust your pH until your TA is correct, as you mentioned Steve.
Apparently it is used in salt water aquariums..
