On 6-30 spotted a few "black" spots at the bottom of our salt pool. After $200 worth of chlorine and an overnight with only .5 loss of FC and I threw in another gallon after that for good measure, I thought I completed a successful SLAM on 7-5. I felt the FC levels were going down so quickly but figured my CYA was already low and FC can't maintain that high just with a salt generator so I hoped it was just going down pretty quickly to lower levels. Afterall, I knew I didn't have a lot of CYA in the pool but I always get a bit confused when I ultimately go into a pool store and they tell me I have enough, I know I have to maintain higher chlorine if CYA is higher, and this page on TFP Chlorine / CYA Chart I was within range. I realize in other places TFP says I should have between 60 and 90.
my CYA 25 (my test)/ 40 (leslie's test)
So, my FC:
7-5 24.5
7-6 14
7-7 11
7-8 7.5
7-9 10
7-10- 7
7-11-7
7-12- 4
7-13 -4
7-14- 3
7-15- 2.5
7-16- 2.5
7-17- 1.5- turned cell to 100%- oops-did I get algae here?
7-18- 3
7-20-3
7-22- 3- left on a 2.5 day trip- kept salt generator at 100% but should've added some shock/chlorine or raised CYA a long x ago-should've checked how long pool is running...? should've brushed pool better due to leaves being on bottom due to monsoon and should've been on top of my DE filter cleaning but waiting for appt next Monday for pool company to look at piston valve and break down DE filter (first time we r paying someone which also is delaying the backwash...)
seems to me this is when algae started forming again since FC got under 2?
7-25-back from trip-3pm= .5-uh oh. added 1/2 gal chlorine and 8 oz of r-0013 into the pool (yes u read right-multitasking with kids and thought it was my bottle of pool h20)
7-25 10pm= 1.5
7-26 8:15 am=1.add bag of shock.
7-26 11am fc= 4.5- spotted 3 spots of black algae at the bottom and daughter is under water brushing with a metal brush..
new bottle of r-0013 should arrive tomorrow. I have 1.5 gallons of chlorine on hand. I leave again this weekend so I'm trying to figure out when to SLAM again. I don't really want to raise CYA now if I have to SLAM cuz it'll be more chlorine but I know I need it to keep the chlorine in the pool. I've struggled with this concept since I've had the pool so if someone can explain if I should raise CYA and how much before SLAM or after and does it seem I never really got rid of the black algae before or did I get it again and when that'd be great! Also, I'm sure it was a bunch of different things that contributed but I never thought that leaves in a pool would matter THAT much, or a full DE filter. They do matter THAT much, don't they? I know I didn't mention the weather and sunny days but I think my pool was staying afloat during those days and the full DE filter/leaves in pool was what made the salt system not be able to keep up but with my levels, what do u think?
PS. the pool company that's coming out to clean DE filter and look at piston valve for backwash will want to add algaeside for algae. I've never tried it due to risks of copper staining... but somexs when I go through this I wonder if I should give it a try. Does anyone here EVER use algaeside or do I just stick to a good ol plain SLAM at all times? At less than $65 for algaeside it's tempting.
Thanks!
