Honestly there is no huge benefit to dosing in liquid form for a 20 gallon tank that I know of. If you had a larger tank, it might give you a bit more consistency I suppose. But I just dose dry ferts straight into my tank. And from what I've been hearing on the forums you might consider dosing less of the traces and slowly increase the amount if you see deficiencies. That's my plan as I switch, because the traces are potentially dangerous in huge amounts. It's unlikely to get there following EI, but I'd rather depend on my plants showing me what they need, compared to assuming they will want higher levels of copper, or whatever. Some are even mixing their own micro formulas. Another 5 years and maybe someone on here will have developed a new micro mix for sale.
