Using the K-2006

[Manslick]

I hear you robbym. I love this site.

So, today I test again.

FC = 2.5
CC = 0
PH = 7.5
CYA = 50
TA = 100
CH = 475

The chlorine, pool calculator says need I gallon, 3 quarts, 1 cup or 236 oz of 6% bleach to bring me back to Mondays level of 5.6.

I have purchased two 90 fluid oz jugs of K-Mart brand regular bleach. The label says 6% sodium hypochlorite.
If I add both it should bring me close to my last FC test of 5.6.
Am I getting this right?

The TA and CH levels. Do I need worry about them? If so, what do I do?
Help appreciated.
TIA

You are doing great! TA at 100 is fine. Your CH is high but as long as your water is not cloudy, you're ok. Just don't use any cal-hypo and don't let your TA get high. BTW - The only way to lower CH is to do a partial drain.)

Thanks again Watermom – a partial drain, hmm. I have hard water here in Louisville.
From the water company - Pure Tap®, Louisville Water Company’s tap water, is moderately hard, at 159 mg/L or 9.3 grains of calcium carbonate per gallon.
So would a partial refill actually help lower my CH level?

Those test kits are fun, aren't they?

At the bottom of the PoolCalc there's a feature called "Effects of adding chemicals" .

It says that adding 180 oz of 6% bleach (the 2 bottles you bought) will raise the FC in a 36,000 gal pool by 2.4 ppm.

Looks like you have things well under control and are on your way to a 5 Minutes A Day pool.

As long as your water isn't cloudy and your TA isn't high and you don't use cal-hypo, you'll probably be fine and don't need to bother with draining any.

I have to add water periodically due to evaporation and a small persistent leak from my filter plug. It has not rained here in nearly two weeks, with hot sunny days in the mid to upper 90’s.

I will monitor the CH level as I recall from reading the K-2006 guide that high calcium levels do something bad.

Many thanks to you and all the folk here.

Testing testing testing – the other day my CC test turned yellow.

Until then it always went clear. The instructions say it may turn pink.

What’s going on?

usually partial bleach out from high chlorine (very high). Try the test again with more DPD powder (3-4 scoops). If it still happens dilute your sample 1:1 with distilled water and test with a 10 ml sample then multiply your number of drops by 1 to get the FC and CC.

Right on as usual Evan.

I had upped my chlorine dose to two 1.4 gal jugs to ward off any potential algae bloom since the temps are now in the mid 90’s here and I had a 4th of July party planned.

So on a hunch yesterday evening I did the 25ml CL test with two dippers and the CC came back clear as store bought glasses.

Thanks for the tips.

Oh good. Thanks for the reassurance.

I will look more closely at the pool calculator.

Yes the kit makes testing way fun.
