Hey folks,
Bought a house with a pool built in 1977 a few years ago but didn't really take as much care of it as I probably should have - I'd get the odd algae bloom here or there if I didn't add the chlorine granules (70% hypochlorite) but I'd shock it and everything would be alright. Relied on Leslie's for chlorine/MA/some water testing at first, but didn't really like the people there so didn't ask for much help.
Then I started noticing black algae growing in the pool and came across this forum looking for advice and saw the recommendations for pool maintenance. So I ordered the K-2600 test kit and here were my results:
FC - 1.0
CC - 0.0
pH - 7.8
TA - 100
CH - 750
CYA - < 30 ended up using all 14mL's of the vial and could still see the dot so seems like I'm low
I have a couple of questions/concerns:
#1 The CH is really high, yet the pool is still clear...I have no problem seeing 10' down to the bottom of the deep end and seeing the drain? When I pull my Hayward out there's a bunch of white chalky stuff that's accumulated on it, but other than that what's the risk of having the CH this high? PoolMath says I need to drain about 50% of my pool to fix it.
#2 Seems like I've got to start adding a ton more bleach to get my FC up - I added about 1.5 gallons of 10% liquid chlorine on Saturday thinking it would get me to 5 but obviously that didn't happen...could this be because I don't have enough CYA and the sun is just destroying the chlorine? The pool gets sun for most of the day. Or is there something in the pool that the chlorine is getting used up on?
#3 When's the best time to run the pump and add the chemicals? Morning? Evening?
