Q: my pool looks like a bubble bath, how do i knock this chem down
11 years ago
1 Answer
A: Thank you for your inquiry. When you use this type of Algaecide in excess it will foam as it has foaming capabilities. It is not harmful but it does show foam if agitated as in swimming. The best way to get rid of this foam would be a defoamer. The amount of defoamer needed depends on the size of the pool.
The best thing to do is backwash,clean your filter and add fresh water and continue that process until it stops foaming.

Q: i have added this to my pool ,now i have this huge bubble bath in my spa, how do i knock this down
11 years ago
1 Answer
A: This product has foaming properties and if too much is added it will cause foam. We imagine the spa is attached to the Pool and you are using the same water? Also the use of the jets in a spa would make this even worse. You can use a defoamer but the best thing to do is backwash the pool, clean the filter and add fresh water. This could take a long time depending on how much of the product they have put in the pool.

Q: J'ai un jardin d'eau qui fait environ 6x6, suis mieux de mettre du 15%
A quelle fréquence doit doit en ajouter et quelle quantité. Il fait 2-3 pieds de profond. J'ai une petite pompe Sunterra achetée chez vous justement, ai-je besoin d'une plus grosse?
Article #59-0418-0
A: Nous recommandons l'utilisation de ce produit #81-3730-0
40% 1 L parce que le 15% va créer de la mousse dans un petit environement. Nous recommandons de ne pas utiliser plus de 10 ml par semaine. Assurez-voius qu'il n'y ait aucun organisme vivant dans votre jardin d'eau.
