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. Â
Electro,I am no expert on minerals. Â I used the Freshwater ag+ cartridge (made by N2 for HotSpring) and I guess it did a good job. Â 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). Â 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. Â (Can you tell I'm not an expert, now?)I have been using more chlorine when I get out to maintain crystal clear water. Â I figure it can't hurt to use them if they help keep your chlorine usage down and your water clear. Â I don't know anything about the Sundance product, but go for it. Â 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. Â I did notice that I had to change my water sooner because of TDS. Â I figure I'm doing good to get ph and alk in line! Â I'll stick to the simple method! Â
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. Â The dealer gets his money from the bank and the bank charges the buyer. Â Therefore, there is no reason not to get a good price on a spa and still qualify for the free financing! Â The only obstacle for someone is their credit score which may preclude them from free financing.
