Hi,

Thank you Stan. Yes, I guess Hagen NPK is enough to cover my macros, even though per dose, give me like 3.5ppm NO3, 0.5ppm PO4 and 2.5ppm K (3-4 times a week), in contrast to what I always target for 10ppm NO3, 1 ppm PO4 and 10ppm K (which is according to EI dosing guide). As for micros, I am using Hagen Plant Gro, for both tank 1 & 2, (tank 2 switched from JBL Ferropol for about a month now). With somewhat more lean NO3 dosing, finally I get some red plants (L. aromatica, stellata, repens etc) to become redder, but on constant look out for BGA...

Having said that, too bad for 88Marine not to stock this great products anymore. As far as I know, their Hagen NPK and Plant Gro are the cheapest. Anybody know where to get this Hagen ferts at the same price as 88? Or maybe cheaper?
The other alternative I would like to try for macros is OceanFree Liquid Fertilizer, which is actually NPK. Anybody using it? How is it?


Regards
