Help - Green clear water

[masspool]

Hi All:

UPDATE

It rained hard today here in Central Massachusetts (the rain is obviously acidic here)

It has been cold the last week or so (32 degrees at night to 55 as a high during the day).... the pool is not heated so the water is very cold.

I came home from work to find that, during the day, the pool has turned from Lime green to blue.

This is strange....don't know whether all of the metal-control chemicals finally kicked in? Or, something else changed (the PH and chlorine both did decrease from yesterday) Or was there something else at work here ?

using a Taylor K2006 test kit, I recorded the following readings:
FC=5.0
CC=0.5 (so TC is 4.5)
-
PH=7.0
TA= 40
CYA = 35 (halfway between 30 and 40)

Anyway, I suppose I should bring up the PH a little (to 7.2 or so) ?

BTW: The pucks are still in my in-line chlorine feeder - and I have not shocked the pool since Saturday - nor have I added any chlorine since saturday (no bleach, no powder) other than via the feeder

I would bring the pH up a little, since the trichlor is very acidic and will drive it downward.

One correction on your chlorine readings. FC + CC = TC. So, it isn't possible for your numbers to be as you listed them above.

Quick Update:

Continues to rain here - and air temps are cool at 45 - 55 degrees

PH drifted down below 7.0 yesterday and I added soda ash last night.

I retested PH this morning and it was 7.0, so I added some more soda ash this morning

TC = 5.0
FC = 5.0
CC = 0

Pool (thankfully) is still blue

I stocked-up on bleach jugs at walmart, but have not introduced anything new to the pool - other than the chlorine that it is getting via the in-line feeder

SO....
Yesterday morning (May 7th) the water was blue (and it has been blue for several days)

It warmed up and was sunny yesterday and the air temp hit around 70 degrees (I mention this because the pool water warmed up as well)

I returned home from work and the pool had changed to a light, very clear, green

I did a quick PH and TC test and the PH was 7.2 and the TC was at 6. Just to be sure, one again, that this is not an algae problem, I added three 96 OZ jugs of 6% bleach.

This Morning the pool is still clear, light green. And, this morning, I broke out my Full Taylor test kit and took a full set of readings. It is raining lightly.

They are :
TC = 11.5
CC = 0
PH = 7.2
TA = 80
CYA < 30 ( I can still barely make-out the dot with the tube filled to the top)


(Over this past weekend I had vacuumed the pool and added Arm & Hammer to bring the TA up to 80 (from 40) - the pool walls and bottom are nice and clean)

I am assuming, with the high chlorine levels, that this is definitely a metal problem.

I need some advice. I did buy a culator pack from the local Leslies ($25 ouch) and have that in the skimmer, but I understand this will take awhile to help.

Should I add some more Metal Magnet to the pool??????


Thanks

Interesting:

During the evening of May 8th, I added a quart of sequestering agent (this is the only thing I added). By last night (May 9th), the pool has returned to a clear blue color. I am cautiously happy.

Hi Mass;

All sequestering agents are temporary in their effect, so the improvement in your water is also temporary. However, if the CuLater works as advertised (we're not sure yet), it's the only product that can remove metals (iron, in your case) from the water even while it's sequestered.

We hope it does work as advertised -- it would be a very useful tool for quite a few people. But, you'll want to watch. They claim a color change as the material captures metal from the water. Also, once the iron begins to be released from the sequestering agent, it will begin to stain things. If you run your pump continuously, what it's likely to stain is your filter (which is OK) and the interior of your skimmer. So, you may want to watch for that.

Good luck . . . and please let us know how it goes. (We'd like to know if the CuLator product DOES work.)
