Re: Problems with algae and milky water HELP Thanks for the information, I never used melamin, but I heard it works :D

Hey pv5490, don't know if I can help you? It's possible to remove CYA by using melamin. Melamin is a powder which is mixed with hot (!) water and poured into the pool. Melamin absorbs CYA and can be filtered out of the water (similar to flocking-products). The amount of Melamin being needed is...

Yes, liquid chlorine is available, but I usually use HTH-Briquettes 7 g. pills (Calciumhypochlorit 65%). My cys level is 0,0. You mean liquid is better, because it doesn't increase the hardness? Ciao Marcus

Hi Jason, anorg. chlorine ist e.g. calciumhypochlorit, org. chlorine is (in germany) chlorine stabilized with cys.

Hi Jason, I will read pool-school this evening, thanks! Changing a higher amount of water regularly might be done to eliminate cys from the water. I'd say 90-95 % of pool owners in germany use stabilized chlorine, 5-10 % anorg. chlorine. With every dosage of org. chlorine the cys-level will...

Thanks for your warm welcome :flower: Ciao Marcus

Hi all, my name is Marcus, 43 years old, from western germany. 4 years ago I started with a 4,57 diameter quick-up pool, last year I changed to a 7000 gallons inground steel-wall pool with sand-filter (50 kg. crushed glas filtration media, grade 1, 0,5-1,0 mm particles), salt-water, no...
