Watering with fish tank water?

I’m starting an indoor grow tent, 2x4x6. I have a 60 gallon fish tank with an Oscar that poops a lot lol. I’ve read online people saying that it can be a good idea to use fish water as it will help fertilize. If I do this, should I be using water soluble ferts less? Or cut them out all together? Any advice or sharing of your own experiences would be greatly appreciated. First time growing any since I was a teenager and I’d like to do things properly this time around
 
Yes, aquarium water is loaded with nitrate and other ions. Some people deliberately water their plants using an "aquaponics" system... you might still need to give a shot some low nitrogen fertilizer from time to time.

Nice, he should be good size in a 60 gal. I had a Red and a Tiger in a 55 and one was pretty huge. And ya that's "Good Shit", and should have some good bacteria in it if you're tank is healthy. Might smell a bit though.

Nothing wrong with using Aquarium water after changes, I have a fish tank and have done it myself.

You dont have to change your normal nutrient program , the nitrates, nitrites and urea levels are generally extremely low in aquriums (or your fish would be dead) its a healthy supplement. Use the tank change water there is no harm, and maybe a little good bacterial boost , when you wash your filter out in tank water , water that to your plants too.
