First of all, I've been lurking on this forum since last summer and I'm amazed at the wealth of valuable knowledge! I have a 26,000 gallon IG vinyl liner pool with an Aquarite chlorine generator, sand filter and 2HP pump. I opened the pool about two weeks ago – crystal clear thanks to the closing instructions on this forum! My PS234 testkit arrived last night.
Here are my first numbers:
FC 6.0
CC 0.5
TC 6.5
pH 7.2
Alk 50
Cal 30
Cya 20
Temp 76
I did the tests around 7:30 this morning. FC 6.0 seems a bit high to me since my pump (and Aquarite) hasn’t run since 4 PM yesterday, especially with Cya of 20. I’m running the pump from 8 AM to 4 PM at 50% on the Aquarite. I'm going to try lowering it to 40%.
Any reason to be concerned with the 0.5 CC? Water is crystal clear.
I just added a quart of muriatic acid two days ago. My pH was 8.0 on a cheap Ace Hardware drop kit before that, so I think 7.2 is good.
I’m assuming that I want get the Alk up to at least 80. Using MWSMITH’s BleachCalc, it looks like I need about 11 pounds of baking soda, but I figure I’ll try a few pounds every couple days and retest in between. Does that sound right?
Aquarite recommends Cya of 60 - 80 and Cal of 200 - 400. I’m leery of taking the Cya up that high, I might just gradually aim for 40 for now. Does Cal matter in a vinyl pool? Do I really need to get it to 200? If these questions belong in the chorine feeder section, just let me know.
I know this is a lot of questions!!
Thanks,
