I bought a house a year ago with an older vinyl IG pool. Over the last year I have been using Leslie's testing and advice. I have had 3 bad algae blooms. (dark green swamp water) After the first one, Leslie's recommended Yellow Out and super chlorination (the print out said to use either dichlor or cal hypo. I was sold Chlor-brite: Dichlor?) and it worked like a charm. (albeit a $150 charm). The second time it happened, it didn't work, so they told me to do it again, which I did. Not a bit better. I had a pool service come out and work on it. They told me I was stabilizer locked, they drained over 25% of the pool, and sorted it out over 10 days or so. ($350 using my own chemicals, not counting my water bill).
After that I tested frequently with Leslie's, they told me everything was fine except my hardness, which I never addressed, since they said it didn't really matter for a vinyl. They started me on Chlorine tabs with a floating dispenser. Shortly after buying the house I had Leslie's Service guy come out to change the sand, and he instead sold me a whole new filter. I probably did need that. The home/pool inspector I used was absolutely ****.
I assumed my main problem was the massive amount of leaves my pool collects, which I don't stay on top of well enough, so this year I took down overhanging oak branches, and 3 pines (More $$$). Now i only have to empty the skimmer every 3 days instead of twice a day.
This summer was rough. about a month ago I started noticing algae on the bottom, which after shocking and brushing started the swamp thing again. Yellow out/Superchlorination of course didn't work (it did go a slightly minty green). Leslie's told me to do it again, but I asked if it was going to work this time, so she looked at my sheet again and said oh wait. Your CYA 100. Do water changes. "Surely you aren't using tabs and Dichlor?" Well yes, on their advice I was. And so I swore to never darken their doors again, and actually started learning about what I was using to keep my pool from going green.
Hi Guys! If you skipped all of that-
I have a light green pool I'm trying hard not to hate. And I'm now a n00b taking responsibility for my own testing and chemicals. I can't see the bottom of the shallow end. There may be leaves on the bottom, but I've skim vac'd and scooped as well as I can. (I keep up well for 2 weeks, then I go on call for a week and it all goes to heck in handbasket. I'll be back to talk about robots soon.)
After firing Leslie's I ordered a taylor 2006 and in the meantime I took out my cute frog tab dispense, I have been occasionally shocking with Cal-hypo, I even threw in a few gallons of bleach, and have been brushing every other day. It's stayed light green. The filter is running 24 hours a day. I dropped the water level with a siphon to about 1 ft below the skimmer and refilled.
First attempt at testing:
pH is off the scale low.
FC: 3.8 ppm
CC: 1.6 ppm
CYA WAY over the top of the scale 100.
Why is the cya still going up?
Should I go ahead and drop the level again? I'm about to get tropical storm karen's assist with dilution/refill. Is replacing half your pool water cheaper than just using more chlorine to account for the high cya? The pool service told me I need to get the water company to put in an irrigation meter. Is this worth doing? I don't usually have to put much water in my pool since I patched that stair leak. Especially this wet summer.
On the pH question, can I add borax alone to bring it up?
Honestly, I would hire somebody to do all this for me if I had the money :P . So the basis of most of my questions is "which option is cheaper." sorry! I know pools are a very expensive pet and a part time job.
