Duane....are all your ingredients water soluble? I don't know much about the chemistry end of all this, but I know that all the elements I've got are almost instantly, totally soluble when I add them to my water table. Sounds like one or more of yours aren't.

If I put them in the tank they are gone real quick put I am tring to make a liquid consentrate that could be dosed at 1- 2 mills Per hour I think I am going to drop in a small power head and see if that helps.
Chelation is the key. If the nutrients are unavailable after a brief period-- less than a couple of days-- that's a sign they are precipitating out. Humic acids are natural chelators.
Iron is a trace element. It is required in parts-per-billion.
