Welcome to our forum.
Hi many thanks for your reply.Some follow up questions:1. Silver ION - how often should this be replaced? (Every 4 Months)2. MPS - This is a type of chlorine right? when should i add this?? Every time i get out after using the SPA? (MPS/Shock is an oxidizer, you are using after each soak to oxidize the waste)3. Where is best place to buy Silver ION from and replacement chlorine (local dealer, online, just google Hot Spring Nature 2 Cartridge)4. Do you use hot springs branded chemicals or recommend another brand? (not required, there are many good brands, avoid Wal-Mart, Target, etc. chemicals...Leisure Time is a very common brand many retailers use)
Hey there! Congrats!I have an Envoy (non-NXT) but same spa, so I will chime in:1. I run the clean cycle whenever you add anything to the water (any type of water care.)2. If you are using the Silver Ion (I am reading #3, and I assume you are) add Chlorine once a week, and MPS after you get out. 3. Whenever you drain the water which should be 4-6 months (unless you use ACE Salt, but that doesn't sound like it)4. What cleaning materials are you referring to? I will use a Mr. Clean Magic Eraser to get the water line off from time to time ($1 anywhere) and use windex if it is dry to wipe out the inside. Other than that, you really don't need anything.5. See above with Silver Ion6. It isn't a bad idea to rotate them since you have 5 in there. That's what I do, then deep clean them in some kind of degreasing solution when you drain and refill the spa.Happy Hot Tubbing!
