Chemical Disaster -

[JamesW]

I would probably not add anything at this time.

Wait for the fc to drop below 10 and recheck everything.

How does everything look now?

Are your filters still turning green/blue/turquoise?

 

[JamesW]

Check the CSI and maybe lower the pH a tiny bit if the CSI is high.

At this point, you're getting close and you should be careful not to overdose.

What is CSI? I do not see that in the kit?

CSI is Calcium saturation index, basically a measure of how much calcium is in the water. Not enough calcium and it is a negative value, too much calcium and it’s a positive value.
Look at Post #139 and on the bottom right hand corner is the CSI level. In PoolMath, click on the box and you should see a value.Do you want to be as close to zero as possible but anything between -0.3 and +0.3 is good.

The shell has random dark spots on the bottom that are not coming off. The water line around the entire pool is pretty bad. The step walls have brown spotting. Everything appears like it will come off with a good scrubbing except for the spots on the bottom of the pool.

We put a new filter in a few days ago. It has a bit of blue in the creases but it is pretty dirty for being so new.

 

[JamesW]

Ok, just keep filtering and maintain good chemistry. You might have some permanent damage from the bad chemistry. Hopefully, everything will go much more smoothly now.

Got it, thanks. When I went back into my Pool Math to add the temp and it will not allow me to update it. Do I need to re-enter all my info again?

When will it be OK to use our heater again?
When we aren’t using it should we continue to keep the bypass closed?

 

[JamesW]

You should be ok to use the heater again.

You will probably get more copper from it for a while until the corrosion is mostly dissolved.

Keep an eye on the heater for leaks as the exchanger might fail at some point depending on how bad the corrosion is.

Manage the chemistry and don't let the CSI go too high.

Should I have the heater serviced? Would they be able to check and tell me if something is wrong

 

[JamesW]

You can have it looked at if you feel like something might be wrong with it.

Most of the damage will be inside the heat exchanger.

If it's not leaking, there's probably not much to see unless you tear the whole thing apart.

 

[LimaBeans]

We are almost there!!!
pH - 7.8
FC - 7.5
CC - 0.5
TC - 8.0
CH - 450
TA - 100
CYA - 50
CSI - .31

 

[JamesW]

Looking good. You got this!

What's the water temperature?

The copper will be in the water for a long time. Hopefully, it won't cause too many problems.

 

[kimkats]

Well done!!! Now how does the water look? Keep brushing the pool to see if the messed up areas change any.

The temp was 71. We have not turned the heater on yet.

The water looks clear. I am going to get in this weekend and clean the stair walls and water line by hand. Fingers crossed the more of the areas will clear up.

Watch the FC closely as the weather warms up and the sun angle changes you may need to buffer the chlorine a bit more. Keep the chlorine to the higher side a little bit just for extra insurance.

Will do!! I have a feeling FC and I are going to become BFFs. Our pool is in direct sunlight with no shade starting at noon until sunset.

Trying to understand if I need to do additional math with this reading to determine how much I need to add. Is the 6.2oz what I add or do I need to multiply by my pool volume?

ALSO my CSI is 40View attachment 328185
