Ive been using aquarium water for my plants quite successfully for awhile now
You just have to be careful about the cleanliness of your tank, else you will be doing them more harm then good if you have too many bad bacteria and possible fish diseases

the jugs are too much of a p.i.a...so I'm using a rubbermaid tub, and an airstone...i switch the airstone between that and my b.d. compost tea....that tea REALLY extends effectiveness of the b.d. compost! I'm sure the algae will help, but that tea is amazing! I don't foliar feed with it because of jamming issues with the sprayer. I foliar feed with earth juice.

o.k. now I need to do a fishtank with lights and lasers!!! anyone whose ever tripped out on the chaotic order of hydrodynamics would appreciate the snow globe effect...I need another hit! the cyanobacteria lives up to its name(blue green algae)....now it's cloudier than a luzianna bayou....I'm thinking about growing enough to make 'cakes' to dry,pulverize, and apply as foliar feed a lot cheaper than the 'sonic bloom' formula.

I've got 2 bucks to my name....and they're drinking a gallon and 1/2 of the algae water per night! I put water out for the varmints; but the deer and the chinchilla killa(the cat) prefer the algae water over even fresh clean water...it's just like lake water...maybe I should get some minnows to fertilize, and eat the 'skeeta larvae. the blacktails here are really tame compared to whitetails back east. they come up on the deck to get at the algae water....animals find water by the smell of algae... I've seen tamer mulies in AZ, but these are coming around more...cat(big) protection of course is one reason...but also the fact that there's very little hunting going on in this county. they're gettin' used to me...even though I snuck up on 'em the other week. I got about 20' away before they smelled me. they love the fact that I'm keeping the pasture watered like it's humboldt county...nice green weeds instead of the usual dead dry brush...it keeps the varmint's occupied so I don't have to shoot their ass!(to keep 'em away from the garden)...besides; I'd rather let the hawks ,owls, and the angel of death( chinchilla killa') get 'em...she likes her breakfast bunnies!

what was I sayin' about "breakfast bunnies"?...not 10 minutes after writing those words; lo and behold...the angel of death strikes again!(another bunny)...she brought it in the office and started crunchin'....she's a barn kitty...lovey dovey- stone cold killer!
