Wow! Thanks Coastal Carolina! Thats for SURE a money saver. I sooo appreciate that tip! I've been rinsing them with water and putting them back - BUT, after it gets too yucky i put a new one in.
tech guy - thanks for your input too! The filters i was going to purchase in bulk are the exact name brand intex filters i buy 2 at a time for 10 bucks at walmart or kmart so i dont think they would be any different but i'm going to take up Coastal Carolina's idea and see how it works for me.
I think - the only factor that I have that maybe many of you dont (and i'm only guessing here), is that I have 6 kids who swim daily all day in my pool and thier friends come over to swim at least 1x week so thats a LOT of dirty kids in my pool - even though they spray off with the hose before getting in, its still feeling like over 100 degrees here and the kids a super sweaty!
So, i'm attaching some more pics here - the filter, the ph/cl test, the hoses, the alkaline test, and the cya test. Hopefully, that will give me a little more input.
FYI - yesterday, I had 19 kids in the pool for at least 4 hours. After they got out, I put the last 1/2 bag of shock plus (trichlor) in, about 1/4 bottle of sanitizer (liquid bleach 10%), and changed the filter to a brand new one. The pictures i'm including of the water are this morning after i vacuumed the pool. I'm also adding a little more (maybe 1 - 2 inches) of water today due to splash out yesterday and the water getting below the out-spout.
Alkalinity after 9 drops:
Alkalinity after 10 drops: (i did this to show the very first 'red' color and if there are any deeper red after adding more)
I added an additional 10 drops - 1 at a time - to see if the pinkish color I was 'thinking' was red would actually turn red but as you can see this is as red as it gets:
