Yes, I've seen most of them. I'm considering something I haven't seen in the forums before.

There are a few things that make mine different. First, I have a 150 gallon tank so if I dilute mine using the method of a digital time + pump for a a minute, I would need a 55 gallon trash can to hold it. Plus the evaporation rate would be quite a bit and potential for spilling.

Anyway, I'm considering using an air pump with a gang-valve and a series of check valves so I could control 3 bottles (Trace, Macros, Iron) all at once. I want to use a digital timer to have a very small air pump kick on for 1 minutes. The gang valve will control most of the pressure and and have most of the out put bleed of with the gang valve, but then I can control the air input to each bottle. Each bottle will have an air input with a tube in the cap going to the bottom and then to the tank.

Anyway, I'll explain more after some testing.
