Chlorine Demend High_Need Advise

[styro]

Hi all,

I ve notice yesterday my water become magi ,greenish color.

I tough maybe cloud water makes me see differently.

I add my chlorine as normal regular addition.

Today morning I measure and was showing zero and I did superchlorinate with bleach with 150ml ( normal day is 50 ml.)

Now after 4 hrs I checked again and again 0 chlorine in my spa.

I did add extra 55g of Lithium as disinfectant.

Can someone please tell me what are my option and what I did wrong to came to the point where my chlorine demand is high.

Thanks

Adam

I just would like to add my numbers before water changing right now.

F.ch = 0.17

T.A =64

PH = 74

temp = 95

CYA = 25

The water is very cloudy.

I did add 55g of lithium hypochlorite 29% this afternoon and now is again chlorine level back to Zero.

Can someone tell me please what went wrong?

Thanks in advance

Adam

Were you adding chlorine based on what you assumed your chlorine demand would be or did you measure regularly and add enough to still have a measurable residual by the next time you soaked? Do you have any CYA in the water since the lithium hypochorite won't be adding any? My guess is that you got behind in the amount of chlorine needed so it got to the point where the FC would get to zero long enough for bacteria and/or algae to grow, causing the water to get cloudy and green.

Yes you right.

After some time (I guess I fill so secure) I did automatically start adding on regular basis same amount of virox.

Without soak 40ml and with soak 80ml.Of course I mesure a water Once a week with my digital meter and before soak or every other day with strip tests.

Water chemistry was fine till 2 days ago when become cloudy.

Can you please tell me, beside changing the water can I save my old refill by adding so much chlorine or is not possible?

Thanks
