is there a liquid i can buy to instantly get tap water to a cycled tank like i know there is an instant sea for saltwater so u can drop fish right in but is there one for freshwater

This certainly is a topic that can be debated. IME, there is no liquid that will instantly cycle a tank, FW or SW. But those additive will certainly help speed up a cycle and are worth using

If you just move you exsisting filter and fish from the 20 to the 45, you should not have to worry about it.

Product like seachem stability will help. There also is a bacteria additive made by Brightwell aquatics that is pretty good as well

Dr. Tim's One and Only has worked for me several times in the past. I wouldn't make any guarantees though...

I would recommend using your filter media from the 20 filter to the 45 filter like Cliff said.

If you want a 'fresh start' so to speak I would use a combination of pure ammonia and Dr Tim's one and only for a fishless cycle quickly, or pure ammonia alone will do the job, just take longer.

so u guys are saying that if i use the 20 gallon filter which is a whisper 60 so it might b able to handle the 45 with the filter pads in it that have the good bacteria in it and just add all the water and gravel from my 20 to the 45 and jus put tap water wit conditioner to fill it up the rest of the way i should b good to add the fish right away ?

Yep, your filter from the 20 is already cycled, and you are not adding extra fish, so you will have sufficient BB for the bioload you currently have. If you have a new filter for the 45, run it as well and it will cycle over time with no effect on your fish

Don't add the water, The BB does not live on the water column.

The filter from the 20G already carries the Bioload of the tank and will continue to do so if you transfer both the filter and the fish to the larger tank.

More stock however will require more filtration.

Why would he want to add ammonia to a tank when fish are going in there? I do agree with a bac booster but you do not use it with ammonia and you don't pour ammonia in a tank and then drop in fish. Perhaps you did not notice he is adding his fish right away?

Yeah sorry I didn't notice he said he was going to add the fish right away. I just recommended the dr tims one and only and ammonia combination because I used it on two separate instances and my tank and pond were cycled in 3-4 days. Dr Tim's website also specifies the use of pure ammonia with the one and only, I can't speak for other bacteria boosters. I was just speaking from experience.
