OK so here is another update-
Haven't tested since 6:30 last night when I topped up to 15 again.
It is 11:30am est and I just tested
FC 10.5
CC 1
I think I am getting close with the cc.
My husband is brining home Filter sand (it stated on our filter that we needed 225 pounds of #20 pool sand) he is also bringing home some CYA not sure what he will get as I told him granular but he might end up with liquid, hope it doesn't matter to much.
Anyways here are some more lovely questions for you wonderful experts.... :lol:
1.Since I am waiting on the sand and CYA should I go ahead and raise the FC to 15 right now..?
2.How do we change the sand in the filter? we don't have the directions (it's a Doughboy)
3.Do we need to rinse the sand before we put it in the filter?
3. Once we put the new sand in the filter do we need to backwash do anything special to it???? (this part concerns me b/c we have never done it and really don' t want to screw it up since we just got the pool sparkling) HELP!

Great!

You have passed an important milestone.
Now you should replace your filter media and then add CYA up to between 30 and 40. After you do that, you want to continue with FC around 20 until the CC level is 0.5 or lower for two days in a row.
Based on your test results, I think the CYA level is currently just a little below 20. That makes sense given what you added and the water replacement you have done. I would add enough CYA to raise the level by about 25.
Okay so here is the long part....
4.As for adding the CYA should I go ahead and put a CYA of 20 in the pool calculator?
5.If I put 20 in as my Current and left 40 as my goal or should I make my goal 45 since it is mentioned above to raise by about 25?
6.Should I shock one more time before I add the CYA and get it up to 15? and if so how long after should I wait before adding the CYA?
7. Once I have the new sand and CYA in I am assuming FC will just drop on their own and my recommended ranges are from 3-7 ppm?
8. Once we get the CYA in and the CC is .5 or less can we swim even though we are waiting for the FC to drop?
9. If we need to cover the pool with our solar cover is this okay to do?
10. Last question..I swear (for now anyways) :lol: How often do I need to test and what do I need to be testing, is it everyday, once a week, not sure on that?
I can't thank you guys enough...
