green pool water

Postby Rin82 » Thu 14 Jul, 2016 11:13

We have an above ground pool, the water is green/brown. The chlorine levels are super low, although we've put a TON in it, and the alkalinity is high (240) I have been vacuuming it multiple times a day, cleaning the filter, etc. How do we get it to a good level? Once it's at a good level, will the water start clearing up? Thanks in advance for the help

I have had this situation myself in the distant past and it was due to a very high cyanuric acid content which renders the chlorine ineffective, how big is the pool and how old, are you in a hot climate?.
My solution at that time, was to virtually drain the pool and start again, but there maybe some other solution which I am not aware of, keep watching and good luck!

Get a decent test kit and post your results back here
What Chlorine are you using (stabilised chlorine will be adding Cyanuric acid)thus rendering your chlorine ineffective as "odbob" suggests
Muriatic acid will reduce your TA and PH, aerating will raise the PH again

You might be having algaes in your pool. They initially go unnoticed because of their size.They are so tiny that they can even pass through filters. If there are plenty of sunlight and nutrients in the pool then this will provide an excellent condition for the algae’s to thrive. Maintaining your pool on a regular basis will help get rid of algae. Here is a blog that provides you some tips on how to maintain your swimming pool http://www.ferraripools.com/blog/pool-w ... balancing/ . A good water treatment is a good option to get rid of algae’s.The growth of algae can be controlled and finally eliminated by repeatedly adding an effective water treatment like an algaecontrol. You could also reapply it if necessary but make sure that you follow the dosage instructions.

Don't guess adding algaecides as they add metal to the water

I’ve owned an above ground pool for 20 years. I’ve gone through several liners and two ladders. I doubt that there is any problem on this forum about pool water that I haven’t learned about the hard way.

What I haven’t learned to be is a pool water chemist. Here’s what I eventually learned. When I get a green algae bloom or if my pool water gets cloudy I just buy some alum and throw it into my pool water. The next day I vacuum it out to waste and I have a sparkling clean swimming pool. I used to get the alum at leslies but my local stores stopped carrying it. Probably because it works so well. Now I just buy it on Amazon. I get 15 pounds at a time for 2.75 per pound. Stop listening to the pool experts who are going to drag out the cleaning process using chemicals that don’t always work and days and days of filtering. Throw the alum in your pool at night, vacuum it out in the morning and be swimming in a nice clean pool the same day.

Elaine, thanks for the alum suggestion, I'll add it to my BBB method of pool maintenance, do you mean pure alum granules, sulphate or the powder, heck of a difference in price :- granules £9 per just 100 gram, powder £1.05 per 100 gram or alum sulphate £7.50 per 1 pound, if you could identify that would be a great help, thanks
