First test readings of season

[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

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

[michael3]

just brushed the walls and floor again, I vacuumed earlier and all I got in the skimmer basket was a few pine needles and a couple dead looking snails lol. water had dipped down to a FC of 19. I added 1/2 gallon of 10% bleach. CC was.5 ph still good at 7.2 It appears the depth I can see down is slowly increasing, but were hanging on to the very light green/ cloudy water. Has anyone ever kept there filter on recirculate while they keep there FC so high? or would that work to kill the algae and it then settle on bottom? or is the filtering of the bleach minimal when pump is on filter?
