Hi,

Yes, it is maybe true, that is how they keep those red plants red. But with such low NO3 level, I wonder how do they (ADA) keeps away those nasty BGA?. I am guessing here, instead of increasing NO3 level (like most people suggest it), they control it by using Phyton Gitt. Don't know if its true or not. But they must do something to keeps BGA away.

Best Regards
