oh, right. thanks

Depends on how you add since formula weights of the two salts are different. If you add equal masses of both salts you'd only be adding about 20% more moles of chloride using magnesium chloride.

Slight scale, cleaned SWG element, NaCl at 4200 by chromate test, still running 100%

I’ve been in a similar boat this past week, almost 30 bottles (6%) and am thinking of going to dry calcium hypo...my water is clear and at low cc of 0.5 and FC of 4, using SWG, but still working on it.....never encountered this before in 20 years, but my CYA is higher than I have ever had...

Cc down to 0.5, FC drifted down to 4, water very clear, very enjoyable to swim (no smell, no irritation). I think I need to double-check my salt generator too. At 20 V and 5 A last time I checked should be ok but surprised not pushing FC higher. Salt level was acceptable by chromate test. Will...

And running SWG at 100 %.

Thoughts on using the bags of calcium hypochlorite to assist in shock? Pool now at FC of 8, CC down a bit to 1.

Thanks! Yes, bottom of pool easily seen. I will add more chlorine, thanks again! This CYA level really through me for a loop. I knew a hefty level was good but didn't realize the unintended consequence of needing more FC.......

I think the contamination I had was pretty mild. I have kids coming in a couple days so want to be a little careful so as not to have too high of chlorine. I tossed in more chlorine this morning. FC is now 11 and cc 1-1.5. Pool water quite clear. I'll do another test tonight and maybe add...

I added a total of about 16 gallons of bleach, FC was now at 5.5, CC at 1.0 using DPD-FAS. I tossed 4 more gallons in, water much clearer....will check later.

12 gallons of 6% so far.... - - - Updated - - - By “hurt” I meant since my CYA was higher than normal I assumed my FC level was still okay not knowing it needed to be higher to prevent growth at higher CYA.

Adding more chlorine...did I initially “hurt” myself by being near the edge of a good chlorine level by having a pretty high level of CYA....?

Update. I opened pool and got in. I must have some organic growth since the vinyl floor was a little slippery and water not crystal clear. I added chlorox to kill.

Will also carry out DPD-FAS test

I did toss in a couple of 1lb bags of calcium hypochlorite the other day to give it a little shock to see if that would help raise level.
