Hello,
I have a gunite pool with many black algae spots and some mustard algae. My CH is also at 550 causing some calcium scaling (it's not too bad). I tested my fill water, and it is at CH 200. I think my pool could greatly benefit from replacing some water. I am thinking because there is so much black algae in the pool and my CH is high, I could drain the pool, clean scaling and algae (while at it, pressure wash the moldy sidewalks around the pool), and then refill with CH 200 water. Here is my concern: I live in Houston, and am scared to think that my pool could pop when I drain my almost 10,000 gallons of water from the pool and the spa. Has any of you TFP'ers done this procedure in Houston successfully? Also, am I correct to think that getting rid of black algae once and for all would be much easier after I drain the pool? What are some techniques to do that and also remove calcium buildup?
Thank you,
Sergei
