Canada eh!
I recently built a 1300 gallon tank in my basement. I would like to know how to properly do a water change.

Let's say I need to do a 25% water change. That's 325 gallon of water that needs to be replaced.

Would this work?

1- Drain 325 gallon
2- Add the necessary chlorine remover in the tank.
3- Add new water

Or do I need to treat the water before I add it to the tank? If that is the case. How can I do it?

Besides trying to do a water change that way why not look into a 24/7 drip. Would definitely make life a lot easier for you.

ON my small tanks I treat the water right before I start the refill. Never had an issue

wouldnt bother with the clorine remover unless your keeping delicate fish tbh...

+1 should had planned it before you've done the tank...
 
I would follow the instructions on the conditioner you are using.

I use Seachem Safe and the directions state:

"May be added to aquarium directly, but is better if added to new water first. If adding directly to aquarium, base dose on aquarium volume. If temperature is > 30 C (86 F) cut dosing in half."

I dose based on the volume of my tank and add water...I've been doing it this way for years without any problems.

Seachem Safe is the powdered version of Prime; it's pretty concentrated and will save you a lot of money over liquid water conditioners. IIRC, 1 KG treats 200,000 gallons and it only costs about $30. If you aren't using it I would look into it.

What are you keeping in the pond? Are you trying to maintain tropical temps?
 
I'd consider getting a plastic rainwater tank that you can use for pre heating and pre treating your water, that way you're using less conditioner and there will be less fluctuation in temp. With a timer for the pump and a drain in your tank or sump you can have a very simple semi automated water changer.
