shock turns pool greeen
shock turns pool greeen
I've had some problems with my automatic chlorinator, so I've been putting tablets in my skimmer for a week, and needed to shock my pool as the chloramines level was rising, and I was getting a few algae spots - so I put some algaecide in at about 6am, and then at about 6pm, I put in about 3 lbs of 70% chlorine powder shock, along with about a pound of soda ash - the pool was at about 7.2 ph - and went inside the house - about an hour later when my wife got home and she looked at the pool, she said - "Why is the pool green?" - and so here I am ---- asking the same question - has anybody heard of shocking the pool causing an algae bloom? The pool is pretty clear, but it has a serious green tinge to it, or maybe it's something else?

Have the water tested for iron and copper.
Have been using metal free
Ouch - when I opened the pool this year, I had some serious staining, and did the whole citric acid stain removal thing, and followed with 2 quarts of metal free (pool is 25,000 gal) - and have been putting 8 oz of metal free in every week since then - you would think that would control the copper - had the water tested this morning, pool company said copper was ok, have not been using copper based algaecides, is it possible a really low level of copper would cause the green?
update
they did, in fact say the copper level was nil, but the store owner said there may be a little copper anyway - however, I did have a phosphorus level of about 500 ish, and I dumped a bottle of phosphate remover into the pool - got rid of the greeen tinge almost immediately, and turned the water nice and cloudy, as was expected. The water cleared after about 2 days, when I shocked to get the chloramines out (up over 2 ppm by now), which also turned the water cloudy, but is now clearing after 2 days - I can see the drain clearly (It's nine feet down), but the pool isn't crystal clear yet, I may have to use a clarifier or flocculant. The chlorine level is staying high, I turned down the auto chlorinator, as the FC was over 10 2 days after a 25 ppm shock. I've had to brush some algae from corners/seams, but maybe that will taper off.
Thanks for all your help. I'm continuing with weekly Metal free, and adding weekly PoolPerfect/PhosFree to the mix - if anyone has any other weekly maintenance tips, feel free to share, seems the weekly $$ going into the pool keeps adding up, but hopefully it saves the rescue $$.

Well, that's interesting.
Phosphates seem to be a highly debated topic. Many people say you shouldn't have to worry about them. Personally, I think when you have tried everything else, if you do have a high phosphate level you should get it down. In your case, you hit on the right thing and that's super.
One thing about the floc/clarifier. Seriously, I resist using those things. Usually, if you are patient enough, and run your filter 7/24 you will clear up in about the same time you would if you used a floc and save a good deal of money doing it. Besides, flocs/clarifiers add a lot of sulphates which can be problematic when built up, too.
Great job! Thanks for getting back with the info.
