so i have been using instant ocean (regular) - the purple box - for years and years... i tested fresh mix yesterday and the alk was 12.5!!!!! I keep my alk around 7.5 so this is unacceptable. i want to see what everyone else uses. i have heard red sea blue bucket is good but want other opinions before purchasing.
thanks!
