Looking to get a 250 gallon tank soon,anyone knows if during water changes i can pour dechlorinator in the tank and then directly fill it up with water from a hose?

Determine your 'dosage level' for your volume and when you start filling with your hose just put your dechlorinator in. Some pour a bit in at a time at intervals, some pour it in all at once.
Be sure to dose for FULL tank volume, and not for just the amount of water you are replacing. So for you, dose for 250g, even if you are only doing a 50% water change.
Yes you can, that is what most of us do. Just make sure you put in enough declorinator for the entire water volume to include filters, sumps etc.
If you decide to use Seachem Safe, the current instructions for 1/4 per 300 gallons is for 1ppm chloramine/ 1.25ppm chlorine in your tap water. Prior to 2014, the old instructionsm state to use 1 teaspoon per 200 gallons treated for up to 4ppm chloramines / 5ppm chlorine. If you know the max dosage of chlorine/chloramine in your tap water, you can adjust the full dosage amount for your tank volume (eg. if your tap is treated with 1ppm chloramine, 1/4 teaspoon for 250g is all that is needed. If your tap is treated with 4ppm chloramine, then you need 1.5 teaspoons for 250g).
Safe is the absolute cheapest way to declorinate. When I was using Prime I would use a one litre bottle every three weeks costing $20 a bottle. I bought a 250gram bottle of Safe and been using the same $25 dollar bottle for years now.
My city uses chlorine for water treatment to 1ppm, so it only take a 1/16th of a teaspoon for my 125gal tanks. Needless to say the bottle of Safe has a couple years left on it.
