Using fertilised tank water for herbs

[dueilangoisseus]

Hello,
I have a dirted tank which I dose weekly with some Reeflowers Aquaplants All Inclusive. I don't use any other medications. Is it safe to use the water I obtain from water changes on herbs and vegetables I raise? I know aquarium water in itself is a good fertiliser for plants, but the fertiliser I dose for the water plus using it to water edible plants and not ornamental ones concerns me.

Yes !!!! I water everything ( except specialist needy plants ) with tank water ( no meds ) and the growth is noticeable . I wash fruits and vegetables before eating anyway.

Oh so tank water that has been dosed with aquarium fertilisers is fine for edible plants? I know those fertilisers are ok for ornamental plants but idk if they would be harmful to health if humans ate plants watered with that. Just to be sure.

I've never heard in gardening or aquaponics that fertilizer use was bad for food crops, chemical or organic fertilizers.

Systemic or topical pesticides, oh yeah bad, they recommend 30 days after systemic treatments before harvesting and eating fruitings, and washing them of course.

I use my waste tank water to water everything, I don't use fertilizers in my tank but fish waste is fertilizer anyways, I don't medicate the tank either.
All in all just allowing tap water to dechlorinate before using it on plants there is a visible difference in pest resistance, growth and condition.

If you are growing "organic" then you probably wouldn't want to use the tank water with chemical fertilizers added to it, but if being "really organic" isnt the concern and just being fresh and safe, it will be as long as you wash the fruiting you intend to eat.

Manufactured or natural fertilizers are just nutrients anyways. Fertilizers, even organic ones when they breakdownbreak down into nutrients and minerals, the same as the lab made ferts.

Disclaimer: I think "organic" is a scam. Everything is organic unless it is a synthetic.

Your fine but i believe some herbs like rosemary might do better with plain water with limited nutrients.

I would not recommend it, not because of the fertilizer but because of anything else in the tank. You don’t know what is in fish food and if it may be uptaken by plants. Same with chemicals you may add, like water conditioners. May be absorbed my your herbs and may not be good for us long term.

I've used my tank water & pond water to water our flowers, fruit trees, herbs, tomato plants, veggies etc. etc. for years & I'm still here (67 years), the nitrogen & other nutrients in it are great for all kinds of plants.
