TBH I make all dyes in 1 Ltr bottles and same goes for the Biocide. Ill take the biocide and make it at a 25% mix ratio as been running tests all night at the effect on the green as its the only dye that is being overwelmed by the biocide.

I asked the maker of the biocide why its happening and they came back and said it because it has a element inside the is a so called "Zapper" it attacks green algi directly via removing its abilty to take in UV light and killing it dead. They said the chances are the green dye is being "Zapped" by this method. Wich is realy intresting. So i need to run longer tests on it to see if over a period of time it reduces the green dye's abilty to reflect UV Green and Green.

At least 1 thing is for sure it works very well at doing it job proably to well. lol
