The ColorQ is MUCH more accurate than an OTO kit; it's just not reliable at chlorine levels above 5 ppm. I'd still encourage you to get a K2006; they keep a long time, and even if you mostly use the ColorQ, there will be times when you need an accurate CYA or CH reading, or when the chlorine is above 10 ppm.

Pool still green, doing the daily 5 gallon liquid chlorine/brush job.

Just had 5" of rain and lot of tree crap in the pool.

Numbers for today (I have the K2006 kit on order).

Looking now for ways to prepare for aeration (considering making a PVC pipe aeration attachment for one or two of the return lines).

Have pump set to circulate and slide is running as I understand my PH is still too high to do a full blown aeration.

[PoolDoc]

You don't have to do aeration fast -- it will take place slowly if you do nothing but maintain a lower pH. So, go ahead and lower the pH. If you can, adjust the pool returns to 'riffle' the water.

Worry about getting the chlorine up, and killing the algae. If it's still green with 5 gallon doses in the PM, go to 10 gallon doses! You'll spend less, killing it quickly than by slowly beating it to death.

Update, water seems to be a lighter green, brushing seems to produce smaller clouds of brown than before.

Numbers of 6/3 Just before adding 10 Gallons of Liquid Chlorine and brushing. Use slide and have returns pointed to surface to aerate. Also filtering again.

=====================

Numbers of today, just before another 10 Gallon liquid chlorine dump. Filter seems to be a lot cleaner. Still use slide and returns to aerate. The returns make the water ripple (no bubbles)

Don't have the K2006 kit yet. CYA number seems strange compared to previous measurements.

It's good that Fleet Farm has the chlorine on sale,

Thanks in advance for any advice/comments etc.

One of the observations I saw about the ColorQ was that the CYA measurements could be erratic.

You need to do another 30 ppm dose (10 gallons of bleach) added in the EVENING, and then do a chlorine test in the AM (before 9 am).

What COLOR is your water?

My CYA reading of the other day might have been a user error (you can put in the tube two ways and the wrong way is blocking the colorimeter "view")

Anyways. Pool water is a teal green. Only able to see the bottom at the shallow end.

My 6/5 8:30am numbers:

FC 1.33
PH 7.0
ALY 184
CH 172
CYA 8

I am sure that I am bleaching out. I tried the over 10PPM FC procedure but those numbers where very strange and I had lack of time for a redo. Have to make money to buy more Pool chemicals

K2006 kit should arrive tomorrow.

One observation my robotic pool cleaner is floating on the surface and doesn't want to "sink" to the bottom of the pool. The clean out of the cleaner showed some regular "waste and some worms" it wasn't clogged anymore with dead algae.

I've got something, created partly with you in mind:

with results here:

+ Get a cheap OTO / phenol red kit. It won't bleach out, at any chlorine level, and will be useful even after you have the K2006 for quick checks.

+ Tell me what % bleach you are using.
