Looking into growing hydro and had a crazy thought. I work at a pet store and know that adding plants to a fish tank improves the water quality because the plants absorb a lot of nitrates and ammonia. Would adding fish to a fish tank hydro system be beneficial to my system by naturally providing some of the nutrients? Or would I just be killing fish and/or my new clones?

well, fish shit. and i doubt that is anything like guano or manure. i have a cutting in my fish bowl. nothing special just a little Beta as a test. but so far, nadda!!! cant say it will root, the stem is soooooooooooooooooooooooooooooooooooooooper long. like 10-12" inches easily. who knows it will even be worth it if it does root.

Fish + ordinary fertilisers = death
You get some aquarium plant fertilisers, but I assume those plants to most of their aquisition through their leaves.
I used to do planted aquariums, its quite a bitch, you had to measure all important nutrient levels seperately in order to feed, adjust carbon dioxide, and lighting as the last two in turn affects pH, screw up and you end with a green tank of algae. It realy makes growing pot childsplay in comparison.

If you want to do proper aquaculture you need to plan ahead a bit though, large enough pool for the fish and bacteria to live in, and a nice reed and rock filled recepticle side to the pool,left long enough to get established (the bacteria, not the fish), and I think you stand a farly decent chance of growing nice bud.

the water in an ordinary freshwater fish tank becomes super-saturated with all manner of things plants find delicious. every drop of waater i took from my tank full of mollies and tetras went on my garden, and i never bought a drop of fertilizer. unfortunately i cant imagine any setup which might allow you to keep fish in a hydroponics system.

1) it takes a long time for fish to fertilize the water.
2) any plant tonics you put on your plants will get into the tank, and kill your fishies.
3) anything you put in the water for your fishies (ick medicine, a heating element, sea salt, algae eating fishies, etc) will be hazardous or lethal to your plant's roots.
4) FUCKING ALGAE
5) you wont be able to see your pretty fishies through the root system
6) fish tanks hate change. when you harvest your plants your fishtank might become toxic
7) if shit goes south and you need to scrub your system, shit will get complicated.
8) how high will your growroom have to be to accommodate vertical cannabis growth, and your fishtank?
9) youll never know exactly how nourished your plant's water is. this is no problem for ordinary plants in an ordinary soil garden, but cannabis cultivation is not like growing tomatoes on the patio.
