I missed the significance of using a sock for my previous additions. I poured right into the skimmer knowing that it would slowly dissolve while being stuck in the cartridge filter. What I missed is the acidic nature of it - hopefully I haven't damaged the heating element with my prior mistakes.Wait until you get the test kit. Also, do not pour directly into the skimmer.
Add the CYA by using what we call the sock method. Get an old sock (no holes) and put the measured amount of CYA you need. Tie the sock closed and either suspend it in front of a return (hang it from your brush pole works with something weighted on the deck) OR if it still allows flow thru the skimmer, place the sock in the skimmer. Every 15/20 minutes give the sock a squeeze to speed up the process. Please DO NOT follow the directions on the container of CYA to just pour it into the skimmer and don't just toss the sock in the pool as the CYA is acidic and can bleach/stain pool finishes.
Sounds like the DE is gone and things are working the way they should be.I just wanted to note that the filter is doing much better today. As stated yesterday we had to pull and clean it at least once per hour. So far today its been going for 2 hours and is going strong.
Half a pound per 100 sf of filter. A lot less than what pool store guy said. Also, this is an old manual and I don't think the newer revisions advise adding DE. I just knew there was a grain (heh) of truth here somewhere.When the cartridge element filter is used on new pools and after cleaning the elements, introduce into the system .5 pounds
of diatomaceous earth per every 100 square feet of filter area, (a one-pound coffee can equals .5 pounds of diatomaceous
earth). Mix the diatomite with water and pour it into the skimmer after the pump is primed and the system is operating. This
will enhance the filtration of your water.
