Here is my chance to ask a dumb question. Why is regular lawn fertilizer not considered "water soluble". Are there fillers in it that genuinely do not break down in water? Would the bottom of your tank end up full of muck?

Another question: where did you purchase, or how did you make your fertigation systems? I am interested in these for both banana and citrus, but have never tried them. I already have a drip system in place.

Comment on micronutrients: When citrus are grown in the ground, micronutrients are typically not a definite need, unless your soil has proven historically deficient. I do not know if this is the case with growing bananas, but I would think it is somewhat similar, since both bananas and citrus are heavy feeders. I do not know if sunfish is growing in the ground or in pots.

Comment on acidity: It is fun to get a cheap pH meter, and test your soil periodically. In Central TX, (where I grow all manner of things with varying degrees of success) the soil is naturally very alkaline (as is the city water), so acidic fertilizers and acidic amendments (such as peat moss) can be very helpful in keeping the pH in that "sweet spot" of 5-7 (at least for citrus and according to FAO, bananas as well).

Cheers,
