yeah, still if I shake it, it not precipitate fast, it took 2 minutes approx.(I check it with a clock) to beggining to precipitate. The only way to dose it well is to shake well and dose fast. You know, I also sell dry fert, but i sell more fast the liquid fert (despite that I make the liquid ferts from dry ferts and everybody knows it). I think here win the easy way to dose (Only 2 products, only fill the cap). I start to use this 2 bottles on my 5G because it is so easy and have all the nutrients needed, but in the 29G Heavy planted I use the dry ferts. Thank you again people and thank you Philosophos.
