I am a new pool owner it was just installed last fall, I have been watching this amazing resource for sometime now I have a question of my own. We also just brought home our second child, and that is what I am blaming this brain fart on!!! I was given HTH Algae stop 15( as well as other HTH chemicals as a sort of pool opening gift from the inlaws), So my pool has been running amazingly thanks to helpful tips from this website, I also drove down to a Leslies store in Buffalo and bought a FAS-DPD test kit, on this sites recommendation. It has been great the water test right in range all the time but lately I had been getting a slippery feeling on the bottom and sides of the pool, no visible algae but I though well i have the chemicals right here I might as well add some algaecide. The direction on the box recommend an initial dose of 135 ml per 10,000ltr of water ( my pool having approx. 84,000ltrs) or a maintenance dose of 80ml per 10,000ltrs. I though I would add the lower amount as there was nothing visible. This is where the brain fart comes in, I in a moment of exhaustion though that there were 100ml in a litre, so I figures i needed about 8.4 ltrs of the stuff which was handy because I had a 8 ltr jug. So in the entire jug goes. no real issues. until about 12 later I decided to also shock the pool, as soon as the shock hit the water , it turned to milk. I panicked ran to this website realized my mistake and am not really sure what to do.... since then the pump has been running full speed fro two days the water is clear, there was a ton of dead algae on the bottom that I vacuumed to waste( looked like sand), and I also backwashed the filter for an extended time, but now I am trying to add water and it is foaming up quite a bit. Any suggestions? Would it be safe to swim in? I have tested the water and these are the results
The Products used:
Algae stop 15 by HTH (arch chemicals)
N-alkyl(40%c12 50%c14 10%c16)Dimethyl Benzyl Ammonium Chloride .......15% 8 litres
Shock Treatment by HTH
(it has no chemical composition on it, don't even see it on website I think it is from Costco) 454gram bags and I used 2.8 bags as per directions of 150 grams per 10,000ltrs of water.
any assistance will be greatly appreciated....
