Greetings,
I am having problems with chlorine loss. Last year I had no problem with swg keeping up chlorine levels. This winter I did a partial drain for winterization. Upon opening three weeks ago, I noticed some brownish powdery substance on pool bottom along with some leaves and stuff as well as some green algae, especially along water line. After filling, brushing and vacuuming I used a couple bags of "shock" and mustard algae killer and phosphree. Pool became crystal clear in a couple of days but I had no chlorine even while superchlorinating with swg. I have been using the local pool store as well as test strips (tf kit should be here today!)to determine I had cya=30. I added cya and strips show close to 100. I will have more accurate data soon. I shocked with a couple of with pool stores powders but I think maybe it was insufficient, so four days ago I added six jugs (96oz) of 6%bleach in the early afternoon followed by six more in the early evening. Chlorine was all gone by yesterday afternoon. Tested stream from swg and it is producing chlorine, salt is good(3200) volts 26 amps 5. Used pool calculator to determine I needed a higher dose of shocking. Added 9 (182oz) bottles of bleach last night(real nice color on test strip!). I tested today for ammonia and the walmart fish kit says .25 ppm or less, but not zero. My chlorine level this morning is still very high.
How long should I keep it this high, is this an algae (still have some brownish powdery stuff) ammonia or a bromine problem because of mustard algae killer. Any one have problem with algae growing in solar panels? I will be adding borates as soon as I get this under control.
thanks
