My 6-year old is dying to swim and I've got green water even with high FC levels

[rox29160]

Whether it is calcium scale or something else, this is the best my pool has looked all year. It is clearing up nicely. It is not as clear as in years past yet, but at least we are headed in the right direction and seeing progress again. I wouldn't be afraid to let my daughter swim in it at this point. I think she might finally be able to swim this weekend. The filter cartridge continues to catch stuff, although it is gradually reducing in the amounts.

My FC is still above 10 but is reducing by about 3 ppm per day. My PH is still 7.2 last night. I still have the Trichlor tablets floating in there so this is still adding some chlorine while trying to continue raising my CYA. Last check CYA was at 35 ppm. Like I mentioned before, I was pretty sure that this was going to be copper so I have the chemicals ordered from Amazon to remove them. I do have some level of metals because I have a brown ring around my normal water level that will not brush off, but Vitamin C tablets make it disappear almost instantly. I plan on trying the acid and Culater process since I have already bought it just to see if it helps. Any possible downside to this way of thinking?

In anticipation of my CYA finally reaching my goal of 50 ppm, thence needing to remove the trichlor floater, I reconnected my Intex Krystal Clear SWCG last night after cleaning. I had the copper ionizer disconnected. I turned it on just to make sure it would work, but after the green light came on for about a minute, the service light comes on and the unit shuts itself off. I knew I wouldn't be able to run it anymore with the ionizer hooked up, but wanted to see if this is what was causing my problem. I reconnected the copper ionizer and tried it again. It still would not work with the ionizer connected. It gives no error codes. The light just comes on and then the unit cuts off. Does anyone have any ideas what this could mean? While cleaning, I filled the entire tube with vinegar and let it sit to clean out the green film that was on the inside of the tubes. I have cleaned it like this before and had no problems. It was working before cleaning and now it is not and gives a service light. Any ideas what the problem could be?

I really like the idea of using a SWCG since it has been so convenient and easy to maintain chlorine levels in the past. If I can't get this Intex SWCG back up and running, does anybody have any economical recommendations on a different system to replace it with that does not have a copper ionizer. I know I can use bleach and the BBB instead, but that is hard to do because we take a lot of trips in which we are out of town for 2-3 days at a time. Being able to use a timer and a SWCG is extremely convenient.

@rox29160: Perhaps a HiC2 pool would be good for you. This is a method PoolDoc's been talking about that intentionally operates with high CYA and correspondingly high chlorine. The idea being that with high enough CYA, you could go a few days between adding chlorine.
@PoolDoc: early in this thread, OP states water source is a poor producing well that apparently has iron.

Have you checked the manuals and videos, here?

I have looked through the manual and watched the videos on the SWCG, but can't find a solution. Searching online, it seems this is often a result of the AC to DC Converter failing. I think this is probably going to be my last season with this pool anyway, so it will be BBB only for the next several months.
I used the acid treatment to remove metals from my pool per the sticky. It is crystal clear once again! The Culater packet doesn't seem to be turning colors so I am not sure if it is catching anything or not. The water cleared up almost immediately after adding the Sequestrant. The filter cartridge continues to filter nicely and it is a milky greyish-brown when I rinse it out now. I am in the process of rebalancing. Hopefully, everything will go smooth from here on out. Thanks for all your help.

As I recall the CuLater is pretty slow acting.
