I need enema advice...

but seriously...

How much of this stuff should I use. Phosphate comes out of the tap at about 1.5ish. Will that be enough for the week or will I need more. 50 gallons, decent stock of fancy guppies and cories with some pristillas, 10 to 20ish nitrates, and am going to start using nusalt for potassium. 2 wpg of 6500k, 5ml of Flourish twice a week and flourish excel as carbon.

How much or how do you measure it out before you put it in or do I even need it..

Oh, and I already know you get yours from greg watson..

Thanks

alright thanks.

I have some oval ludwigia in there, should I add more Iron to that mix because I do have some flourish iron also
