I run aquaflakes in a recirculating dwc.
I just add the A into the system, then add the B, then additives, then ph. I don't premix first, and so far no problems. Running at 1000-1200ppm at .5 conversion. I haven't tried higher ppm yet with aquaflakes although I've ran lucas up to 1600 ppm before.
I like ur style! Much like gb, I 'git er done'.. Into a 5 gallon bucket of good water, I measure out my A, put it in.. measure out my B and put it in.. circulate it for about a minute, pH it, ad my ads and feed my girls.. nobody bitches and everyone is generally happy.. especially me at harvest time..
