First, I'd like to say this forum has been awesome! I've learned a lot since I started lurking around, and even bought a TF100 test kit!
I have been putting this off for some time now as I've always thought pool maintenance would be very difficult. Fortunately, the tests were pretty straight forward. Now I need to know a few things. Here are my specs and test results...
14,500 IG plaster pool with a DE filter
I think my pump is a 3/4 HP, but don't know the flow of the filter
According to the pool calculator I need to drain approx 1/2 of my pool and refill. My question is regarding some stubborn algae, both green and black, that I can't seem to get gone. Should I use a muriatic acid wash after I drain the pool, or could I just use my pressure washer instead, or both? Also, if I need to use the acid does it need to be neutralized afterward?
Thank you in advance for any advice!!!
