Help with my pool numbers...

You need to get some chlorine in there, and I wouldn't wait until you get the alk lowered.....if you're not careful, you're gonna end up with a swamp!

If your pool is green it's probably algae-infested already--metal remover isn't going to do anything.

With a CYA of 100, and water getting green, you need to shock your pool up to 25ppm of chlorine, IMMEDIATELY--as soon as you see this post....don't read any farther till then...

Now that you've raised your FC to 25ppm, you'll have to keep it there--check 3x/day and adjust as necessary until your pool is clear and blue.

Alapool,

Hmmmm. I'm not so sure that immediate shocking is the path to take. The problem is you may precipitate out the copper that's in your water.

Perhaps Marie or Ben will see this post and can get on board and let you know if that .6 copper is an issue. I have never had metal issues so I have no idea if that amount needs attention or not.

I notice you've been using a sequestering agent so you must think it's a problem or someone else has indicated it is.

From other metal problems I've read about on the forum, shocking may actually aggravate your situation. No doubt you've got to get the algae taken care of...I'm just not sure how to go about it.

I don't really know at what level copper is a problem but I do know that LaMotte's water testing procedures ( and their chemistry is sound and accurate, on par with Taylor's) recommends dealing with copper whenever it is above .3 ppm or (so they say) possible staining can result. Ben can probably answer this one better than me.

When I said my pool is green I meant to say it is clear green. It doesn't appear to be any algae (well maybe some) growing. I was thinking that it was clear green because of the copper but I may be wrong. I am going to test again tomorrow.

How do I get Ben to reply to this?

Thanks everyone!

Clear green water can certainly be an indication of copper. Shocking would only possibly make the situation worse. I would try the seqestering agent according to directions--some require you to let your FC levels drop and lower your pH, some don't....also some work better than others...don't know if that is cause and effect.

If the green clears and the copper readings go down then you know you are on the right path

My question is where did the copper come from. If you put it there in the form of an algaecide then .6 ppm is not necessisarily that high. If it is coming from your fill water or pipes or heater then there is a problem. If it's coming from an ionizer...IMHO, get rid of the thing!

Before I became aware of this forum (and boy I'm glad I did) I was actually thinking about going with an ionizer. So I added an algeacide with copper in it and even last summer I added the same thing. The little bit of copper in the algaecide last year really cleared up my pool so I thought I was doing the right thing by using the same algaecide this year. So the copper came from the algaecides that I used. I also used a Pool Frog system the last 2 years.

Then I came across this great site. No more copper for my pool.

Thanks for your help.
