Welcome to our forum.
needaspa,The special 2-year no-interest financing was apparently arranged for all Jacuzzi, Sundance and Sweetwater dealers thru Wells Fargo.
Electro,I am no expert on minerals. I used the Freshwater ag+ cartridge (made by N2 for HotSpring) and I guess it did a good job. My dealer recently quit selling spas, just pools, so I am having trouble getting the Freshwater ag+ cartridge (which fits in the filter of my Vanguard). I have been told I can use the regular N2, just to be careful because it is smaller and may be hard to get out if not rigged right. (Can you tell I'm not an expert, now?)I have been using more chlorine when I get out to maintain crystal clear water. I figure it can't hurt to use them if they help keep your chlorine usage down and your water clear. I don't know anything about the Sundance product, but go for it. What do you have to lose? I bought a Taylor Test kit and can test for calcium) I wasn't sure it did any good. I did notice that I had to change my water sooner because of TDS. I figure I'm doing good to get ph and alk in line! I'll stick to the simple method!
Does the Taylor kit have test for TDS?
There is no cost to the dealer as far as financing thru a third party like Wells Fargo. The dealer gets his money from the bank and the bank charges the buyer. Therefore, there is no reason not to get a good price on a spa and still qualify for the free financing! The only obstacle for someone is their credit score which may preclude them from free financing.
