New Grower Fish tank water

[Miura]

Hello folks,:tiphat:

I've found myself wondering if I can use the water from my tank to water my plants, its at the perfect temperature, perfect PH, plenty of oxygen and has a good amount of nitrates in it and other than water conditioner and food no other chemicals etc are used.
My tanks holds around 330 litres and I throw away about 80 litres of tank water a week and that seems like a waste of good water, so does anyone here use their tank water to water their plants?

Plants love it and it makes a great base for compost teas. I have kept fish for many years and add a little salt to the water. I believe that salt has caused me issues with young plants in the past. If you do not add salt to your water you have nothing to worry about!

Most likely your plants will love it.
I have seen hydroponic and aeroponic gardens using recirculated fish tank water with food fish being raised in the tanks.
The only feed the plants got was the byproduct of the uneaten fishfood and the fishes wastes.

id wanna be sure my fish tank filter is always up to par , access ammonia can be an issue , or i think its ammonia , been a few years since i looked into it

but yeah , be sure the tank has a good filter and your good to go , when i was healthy and had the energy to care for house plants thats the only water/feed they got and they always looked good

peace

Thanks for the input folks, I really appreciate it.
I've been thinking and I'm wondering if I would get any problems when its time to feed them nutes? Or if the nitrates in the water might be too much for the youngsters to handle.

Unless you are heavily overfeeding your tank, the levels of nitrates, nitrites, and ammonia are going to be very small.
Now a tank with some big fish and a small filter is going to have large raises and falls in levels after feeding the fish.
But really, the H2O from a well established fish tank is generally wellsuited for straight watering or mixing with nutrients.

I'm not worried about ammonia or nitrites , I have a mature and stable external filter and its rated to twice what the tank needs.
I'm pretty good with my tank maintenance and I test the water before each water change and nitrates are rarely above 50ppm.
Anyway thanks you've made me feel better about doing it so I'm going to give it a go and I'll report back here on its effect.

I've been using tank water for my grow. The plant seems to be responding well so far. I know my water sits at 6.5 ph, without the need for any ph buffers.
