Welcome to our forum.
what's the benefit of using Muriatic acid over PH Decreaser dry acid besides that it's cheaper?does one work better than the other? does one have a higher tendency to corrode your metal in the tub, or do some other sort of damage, etc.?
so you are saying put the dry acid directly INTO the filter area? like take the filter lid off the Sundance spa, and pour the dry stuff right into that area? Sounds like that is only going to clog up the filters and then never make it's way through the rest of the water?
holy crap, what are your initial tap water alk readings? how about your initial Ph readings?
I thought my initial alk being 240 was WAY high, and my ph at 8.7 was ridiculous for tap water.. guess I don't feel so bad anymore.
BTW.. is it bad for your skin, eyes, anything to go in your spa when the PH is high, like in the 8+ range? or how about when the Alk is high, like in the 200ppm range? I wonder because I don't know if people say high ph and high alk is bad for your body to be in or if it's just right. I figure, if my tap water is that high, everytime I take a bath or shower, I am in water that is alk of 240 and ph of 8.7 and so far I am still here!
also, my water is high, my total hardness is about 320ppm or something, so if you use the 70% rule for calcium hardness, I guess my calcium hardness is about 225ppm,, but again I CAN'T test JUST calcium hardness, only TOTAL hardness. But since I CAN'T lower my hardness I just use the stain and scale protectant chemical stuff.
Wow, I've always added my ph down products (dry acid) directly into the filter compartment. This is what the Hotspring manual recommends. I've never diluted my dry acid. Never thought about acidic water damaging the pumps/heater etc. Should this be a concern? Perhaps the HS components are built for this kind of abuse?
We don't recommend putting chlorine or bromine pucks in the skimmer for this very same reason. Low pH products in the skimmer/filter will slowly destroy heater elements, seals, etc.
