First test readings of season

[michael3]

The granular shock was the aqua chem shock xtra blue, says 63% dichlor, .26% copper, 36% other. the test kit I have is an old PS233 from Ben years ago, I have new reagents and it has always worked well for me

[BigDave]

I would avoid using any more of that shock. Copper is not a good thing to have in a pool. Dichlor is fine when the pool needs more CYA and lower pH - this is not really the case here.
I don't think the PS-233 had Acid / Base demand test (pretty sure Ben felt these tests encourage "one huge dose" adjustments). So... Add some Borax, let it dissolve / mix, test again.

Got some more borax in the water, going to test later this evening, Just a couple questions, at lunch time I tested chlorine level and it is holding and my CC was 0 down from 1.5 yesterday, but still no change in the water color. if the water is holding chlorine and CC is 0 shouldnt it begin to improve? I realize it will take some time I just want to see some change. At what point would I consider maybe doing a large water dump and refill

Just came in from brushing the walls and floor, tested also. FC was at 22.5, going off the cya test yesterday of 55-60 shouldnt 22.5 be ok as a shock number? CC at 1.0 PH up to 7.2 and tested calcium and it was 30? water remains the same, you can see probably about 8 inches down. it might be a tad lighter green but looks very cloudy as well. Ive noticed no huge difference on my filter pressure either, staying about the same as it always does, I know the gauge works, it drops to 0 when off and I get different pressures at backwash and rinse

[CarlD]

You are just going to have to maintain FC in the 20's, run your filter 24/7, vacuum to waste everyday, and backwash, then see if your pressure drops.

[BigDave]

Don't worry about the Calcium - for now or probably ever. Now that the pH is above the bottom of the scale (in safe range) just worry about killing all the algae - it'll be dead when the pool turns from green to cloudy gray / blue.

Just came in from brushing walls and floor, FC was at 22.5 CC 1. PH still 7.2 Lastnight I dumped maybe a quarter gallon of the 10% bleach in, I didnt test it because right now I only have the .75 size bottle of reagent, so not sure how much that would bump my FC upto, maybe 1-2? so there was some drop off but not alot. I think I am starting to get alittle of the grey in the green tint
