Looking for a second opinion here as we have had some very high chemical bills since opening up our pool less than a month ago. The common theme of the year so far has been open the wallet and it's getting old fast.
Pool is about 80000 liters, outdoors, vinyl liner, inline chlorinator that gets loaded with pucks, pump that runs 24x7 and a new filter that has zeosand in it. It is also heated and kept around 85f.
The last two test results have come back much better as a lot of water has been pumped out and refilled. We had a point after opening where CC was at 3.5 ppm following a week and a half where a total of 25 gallons of liquid chlorine was added first 5 gallons where it only made more CC, next 10 gallons where it was unchanged and finally another 10 gallons where it finally began coming down). We have not had green water since the initial opening but it has been very cloudy until this week. It seems that phosfree treatments and repeated shocking as slowly helped. We have followed the pool stores recommendations since day one of opening.
The problem we are seeing now is that the chlorine we add seems to disappear very rapidly still.
This test was from Jun 23rd:
The following was done after this test result
- Phosfree added to try and remove phosphates (this was at 3500 ppb as neighbors lawn care company might have contaminated pool, pool opened at end of may with 400ppb). The week prior was spent trying to clear the phosphates and it has progressed slowly. We began vacuuming the precipitate at the bottom of the pool direct to waste rather than back washing it out of the filter after and this helped greatly.
- Added 5.5lbs Cal Hypo 65% shock evening of Jun 24th, pool left uncovered until evening of 25th
- Added 20lbs buffer in three doses. First was midnight at June 24th, second was 8am June 25th and the final 6.67lbs was 2pm June 25th.
Test result from June 26th
The following suggestion has been made following this test
- Add 3.3lbs Cal Hypo 65%
- 7 ppm CYA increase between tests I assume is coming from the pucks in the basket and the automatic chlorinator. Are we introducing too much CYA to the pool?
- Is the Calcium level going to become problematic if we continue utilizing Cal Hypo in quantities like this?
- Finally, is the .42 CC a concern since it went up slightly since the test three days ago even with such a heavy shock and no swimmer load? Do we just continue on course adding chlorine(possibly switching to bleach or liquid instead of Cal Hypo and pucks?)
Appreciate any feedback that you might have!
