Setting up a new tank advice

[amazontank]

I am gonna set up a 300 gallon tank for my pair of black ghost knives try and get some babies.

My idea was to take all the 12 liters of substrate out of an Eheim 2080 and line the bottom area of my new sump the part that will be under water. Then fill sump up with bio balls and grab some stability bacteria bottle and dose the tank every day and have a few Rhapael cats in there to get things going.

My question is am I missing anything and can I add the ghost knives right away?

My fish guy says to wait 6 weeks. They are some of my priced fish.

Any advice would be appreciated.

There is probably little amount of beneficial bacteria in the substrate. This is highly debated but I believe it's in all in the filter media. Can't you just swap the media in your current tank into your new one? If you take all your existing media you should be able to add the knives right away.

Use same filter media and your golden

To the way you are doing it you would have to wait for some time for the tank to cycle, but if you already have the fish in a tank if you just move all there filter material over from there old tank to there new tank you should be fine, with only a small mini cycle.

Actually the "substrate" is the Eheim filter media and its seeded running in the Eheim 2080 for years. So that was the plan, transfer the dirty filter media lining the bottom of my new sump and then add the bio balls.
Then to make sure things go perfect I was gonna add some microbe lift and microbe lift night out additives along with some microbe bacteria gel I was gonna brush on a few 8"x4" blocks of cermedia.
I'm not gonna worry to much about the water just do a dose of Prime.

Okay now am I missing something now that I cleared that up?

Sounds like a solid plan to me. maybe even a little overkill
