Hi, I have a Sundance 680 series hot tub which is about 2 years old. Haven't had any issues except about a week ago on an excessively hot day (it had been over 100 outside for about a week) I suddenly got a Fl2 error code. Pump 1 still worked at low and high speeds and pump 2 still worked...

I'm a big fan of ahhsome and have gotten great results when using that for my purge and flush. So now I've been using Aqua Clarity for almost 2 months now and was wondering if I should be putting my jets on full blast with the air controls open or is it enough to just circulate the water with...

If I use a water softener to fill my tub, resulting in the fill water having a calcium hardness of 0 ppm, is that OK? I'm talking about a normal Sundance hot tub not a plaster one or anything. Will there be any effect on the plumbing or heater or components? I know I'll have issues with...

When my hot tub arrived it came with a white scum sponge that I'm supposed to leave in the hot tub to suck up oils and scum. Then once it gets all nasty throw it away and put in a new one. I wasn't going to buy another but I figured I'd keep it in the tub and see if it does anything. I haven't...

I got my Sundance hot tub last week and thought I'd try it out for a week before doing a full ahhsome purge. Well, today I used ahhsome and wow! Thick disgusting green sludge made a ring around the shell. This is a brand new hot tub. I've already noticed the tub eats far less chlorine. The...

Hi, just had a question regarding where to drain the water after using Ahhsome. Is it safe to drain it on the lawn or in the yard? Should I let the chlorine dissipate first? Or will it kill the plants? Thanks!

Hi, I know for a lot here SWG are popular in the hot tub and it seems like most of those people like the saltron mini. Is there a reason to prefer that one over the Chlormaker (different company, similar pricing and function) or the smarterspa (automatically monitors and adjusts chlorine...

Hi again everyone, my next question... I recently purchased a sundance hot tub (Edison) and it comes with the clearray UV system. From what I understand from reading these forums and this website, the UV is of little benefit and will essentially eat up a good bit of FC. Do you recommend just...

Hi, I was speaking with a sundance dealer and he said that an aftermarket SWG will void the warranty because it will essentially corrode and pit and damage all the parts. He said if I was really insistent on using one that I should wait until the warranty has expired. I read the Sundance...

Hi everyone, I'm hoping someone can give me some insight as to using soft water or normal city (hard) water to fill the hot tub. I use potassium for the softener, not salt. Is it better to use the soft water to fill it? Will it affect the chemistry if I plan to use the smarterspa or saltron mini...
