Can't figure out why my water is green

[Kcas0772]

Hi,

I have an intex pool, 18' round. I filled up the pool almost 2 weeks ago, and the water was and still is green. I even got my water tested and the clerk couldn't tell me why. Here's all e info. The water is free, however it doesn't seem like algae to me. I have one of those test kits where you add 5 drops to test chlorine and ph. The chlorine is an orange color which I've never seen. The ph was high so I added acid which brought it slightly to low so I added soda ash to bring it back. The chlorine eventually got he color back into the yellow color, but with all this change to ph/chlorine levels, it had no effect on the color, better or worse. So then the last two days I started shocking it a lot to see if it could be algae. Again, no change at all in the pool color, even bough the ph and chlorine levels are high. So I went to Leslie's his morning to get it tested. Here are the results:

FC. 5^
TAC. 5^
Ph. 8
Tot ALK. 50
CYA. 20
Calcium. 40
Copper/iron. C 4 = .3

The clerk said other than chlorine and PH being high he doesn't know what could be causing the green. One other thing I should add, when I filled up the pool there was a lot of leaves/dirt in it. I though that was the cause at first but I've vacuumed so much and ran the filter for two weeks I can't imagine that's it. Thanks in advance for any help!

Did you fill from a well?

No, right from the hose.

Hi,

Over the last week and a half, I've only applied chlorine/shock, and a few days ago dry acid to bring the PH down. But all of this was after my pool was already green. Last week I added a couple bottles of shock hoping this would help clear up the pool, did nothing except shoot the PH levels and chloring levels up. Anyway, so I haven't added any chlorine or shock since late friday. The levels based on my 5-drop tester showed the PH about 7.2. The chlorine is still a littel high, but at least it's not orange. The water definitely looks better today, but still green. The water is otherwise fairly clear.

OK, I've got an idea of what you're dealing with, but if I'm right the problem will be with you for awhile.

Do ALL of these things:

1. Complete both the pool equipment and pool test results as fully as you can. (I could ask all the ?'s, but this is easier for both of us.)

2. Open your filter OR backwash, and tell me what COLOR the goo on the cartridge, or the discharge from the filter is.

3. Take a look INSIDE the back of a china toilet (not: old cast iron!) in your house, and tell me what colors you see.

. . . meanwhile, keep your chlorine in the dark yellow range.

Hi Ben,

I completed the two tests above. I will complete steps 2 and 3 shortly and post the results.

Thanks!

Ok, just did steps 2 & 3. The water appeared to be clear in the backwash and the toilet bowl tank. I did just backwash yesterday though. Usually when I backwash the water will be dirty for a few seconds and then run clear.
