Hi,
After owning the pool for several years, I thought I know it all but apparently I got things wrong. Long story short, we've been having out of control algae due to very high CYA (129) so we did as suggested by replace more than half of our pool water with fresh water and shock while doing that. Here is my current reading:
FC - 0.09
CYA - 49
TA - 143
PH - 7.9
CH - 180
Per pool calculator, it suggests I need to add muriatic acid to bring down the ph and then aerate to bring up the ph. My questions are:
1. So I added the muriatic per suggestion to bring down ph to 7.0. What's next? How long do I have to wait before proceed to next step? 4-5 hours?
2. Then once my ph level will be at 7.0, the pool calculator suggests to add borax to bring up to 7.6 which in return help to bring down the TA level. Is this what aerate means? I never fully understand what/how to aerate the pool? Is just adding the borax enough to bring up the ph level? Of course I will have the pump to run all the time while doing this. Is this enough?
3. I also need to add shock into the pool. Right now it's 0.09. When can I do that? During/after step 1 or step 2 above? Can I add now? I'm so terrified of algae that I'm afraid if I don't have enough chlorine, the algae will grow back.
4. When can I increase the CH level? After all the steps?
Is this enough to help killing the algae? Do I also need some algae killing chemical on top of these? Sorry for the long post but I feel so defeated with my pool at this moment.
