At one point the solution changes from green to mostly red, not green anymore, and one more drop and it’s solid red. Which is it?

I’m sorry I meant 0.25 not 0.025. At 50 TA, is 0.25 CSI not detrimental to my plaster?

Thats good to hear. As for me, my problem turned out to be a calcium clogged cell. I never even checked this because the cell was only a few weeks old and I keep up with my water chemistry (or so I thought). I run my CSI slightly high as I thought it was better for the plaster. After cleaning my...

Wow I did not know it could happen that fast. If I lower my TA to 50, -.025 won’t be bad for my plaster? At TA 60 it would be -.09. The SWG seems to constant raise my pH, but I am good about dosing with acid twice a week.

Yes calcium scale from post 51.

Thanks. Any idea how my brand new cell gummed up so fast? I was literally a few weeks. It taken month for this to happen previously with similar water chemistry.

Ok. I have a waterfall but a 1.5hp pump is a lot of power to run for a while on top of the pool pump. Is there a quicker way to aerate like something hooked to an air compressor?

Do I need to lower the pH to 7.0-7.2 at one time to lower TA or can I do it gradually? My daughter has swim lessons tomorrow and then I'd like to swim this weekend. I have a waterfall to aerate.

Thanks. I am going to start by lowering my TA to 60 and go from there.

Ok then. Sounds like I need to add more acid to keep my pH at 7.5 or drain some water to lower my CH.

So I SLAMed last week and although I passed a OCLT after about one day (12hrs) of SLAMing, but to be sure I kept it going for another day since I had plenty of LC on hand. I still had trouble holding FC so I bumped up the CYA to 80 and it helped a tiny bit. However, I caught a glimpse of...

I’m just gonna SLAM to be sure before I raise the CYA. If I spend 20 bucks on LC for the SLAM to be over in a day or two it’s cheap insurance.

Went from 10FC .25ishCC (very slight pink) at night, to 9FC and 1.0CC in the morning. Do you think I should SLAM? I'm thinking it couldnt hurt and should be a short one. I typically have zero CC.

Got home today and did an FC test. This is the first time I've ended up with positive FC instead of losing with this SWG. Today was rainy in the morning, sunny during part of the hotter times then rainy again so pretty low UV. I now have less than 0.5 CC but not zero. I had 9.0FC this morning...

I am not sure what you mean by this.

Sounds about right. Would such a test still be valid with 1.0CC? I would think no right?

Perhaps I should run my SWG over night to see what it adds with no UV?

Thank you.

Yes I was using 4-5FC a day. A little high as its usually 4ish but its crazy hot outside and my CYA is 60. I usually keep it closer to 80 during the summer. Water is clear. I cant explain why my SWG isnt keeping up though. If you think CC is not a reason to slam, perhaps I'll do one more OCLT...

It doesn't make sense to lose 6 FC at night with no UV or bather load but only 1 during the day. Also weird that you gained .5 overnight, but one drop variation here or there is not impossible. I would double check your testing methods for consistency. Do you have a speed stir? Are you holding...

My tube is cracked so I ordered a new one, but apparently I got the small TF-PRO size and I have the TF-100 size. Not worth returning a 4 dollar item and I like that this one uses less reagent though. How can I use this one accurately with the dropper bottle in my TF-100? Is it just 50/50 pool...

Well I got home and the SWG still isn't keeping up. I had to supplement with some LC. I did an OCLT and I only lost 0.5 but I have 1.0CC so I guess I need to SLAM again before I can blame the cell. I am going to replace some water to bring the salt and CYA down. Slamming with CYA of 60 really...

It does make a difference. You can change it but mine is set to RJ30+

Its for sure not stuck on 77. I guess I'm going to bring the salt back down to the recommended level after this rainstorm. I have dealt with DSP a bunch and they will 100 percent not help until I do that.

Its 93 and change. Pretty on par with what it feels like and what it was with the old cell and control box.

I don’t have a thermometer but it feels accurate. It’s pretty warm. It shows 92F.

Now my high salt light is on, but I still see the hazy bubbles. Could this be hampering my FC production? I know low salt shuts the cell down but the manual doesnt mention much on high salt. My test says 4400 which is close to the SWG readout. We are supposed to get rain from the tropical storm...

How did things turn out? As I predicted, DSP said my cell ran fine for an hour so they sent it back. The intermittent issue I was having before was now a solid problem. I could not even get the unit to start generating. They seemed stumped so they offered to sell me a refurb control module with...
