Coming up on the first year of my Sundance 880, learned a lot along the way, but have a few more questions...

This sure has been a learning experience and I have learned all of my information from here, so thank you all for that! After a lot of testing, I have found this strategy to work mostly well for me.

-Once CYA level reaches 30-40 using dichlor I switch to liquid chlorine.
-We use the two of us use the tub a lot and after each use I add about 3oz of chlorine.
-Rince filters with hose every month or so
-I have to add more chlorine every 3-days between use otherwise the water gets cloudy and lots of bubbles. I can usually get it back down after a few days of keeping chlorine at or near SLAM levels.
-Change water every 4 months or so using an Ahhhhsome purge

The questions I have:

-Is it normal for the plastic on the filters to fade some? I noticed mine are doing that and I am not sure if that is a sign of something wrong with the chemistry. Assuming it is just from chlorine.
-The cap on the inner filter came unglued today. What could cause that? Time for a replacement I guess.
-Does adding 3oz every 3-days seem too often? If it goes to 4-5 days all havoc breaks loose. I thought having the UV ozone thingy would help, but I guess not. I did read the AC would help with that which is why I am considering that now, but is is expensive
-Is there a better way to clean the filters rather than rinsing with hose?
-How often do you replace your filters? The price of these add up quickly if I follow the manufactures directions.
-I started reading about the Aqua clarity from the same company that makes ahhhsome. Sounds to be promising. Any feedback on that? Is it more cost effective to use the Gel for purges and the AC for daily maintenance?

I expect the plastic to fade a little over time.

Two of use our tub every day. I add 2 oz liquid chlorine am and pm. I think you will be much happier adding small amount of chlorine daily.

I use Aqua Finesse on a weekly basis. I purge every 6 months with AhhSome gel.

What do you do if there are gaps in your usage?
 
Plastic does fade. If you have ozone then that does a lot of off gassing which "helps" things deteriorate.

My suggestion would be to put enough chlorine to get 3 PPM at 20 minutes after adding. Then test it next morning and then around 24 hours to see how the chlorine is doing. Once you get an idea then you know how often you need to add chlorine. If you're going into the tub and you have an idea that it's low you can add just enough chlorine to get it at 3 PPM.

I used to measure out the chlorine and put it into a medicine vial to just toss it in. If you go away, slam it before and after, test after 20 minutes before using to make sure chlorine didn't get used up.

I used Ahhsome purge but not their other product.
 
My first outer filter lasted 2 years. I change the inner yearly. I hose off the filters. When I purge I use Ahhsome filter cleaner in a 5 gal bucket. Has to be flipped halfway cause it sticks out. We don't use it as much in the winter. But we go in clean and that helps a lot. I have a scum ray floating that catches oils. I also use the AquaClarity. It helps keep things clean also helps with ph.
