so I have my 240g up and running but no media in the sump. I have a cascade 1500 that's running my 75g. all the residents are moving to the 240. since the only variable is the amount of water in the system what problem if any could occur with moving the filter media into the sump? not sure it would be an "instant" cycle tank but I don't want to expose my fish to a spike if any were to occur. I also really don't have much time to cycle it from scratch( fish are out growing the 75) nor do I trust the instant cycle products. thoughts?
water volume vs established BB

I wouldn't worry about it. You're not increasing the bioload. I suppose if you had an accurate enough test kit you might find that some of the bacteria would die off due to the lower concentration leading to a tiny buildup of ammonia which would then fuel a growth of bacteria. But that's the kind of variation you'd see day to day if you don't feed the fish for a day.
So...Uhhh...Don't worry, you're fine enjoy the big tank.

it is true that you are not increasing the bioload but you are increasing the volume. If it were me i would start the new tank with a filter and seed it with media from your 75 and keep the fish int here a little while longer. I see what you guys are saying but im just a worry wart lol. i assume with the bigger tank You are planning on adding more filtration anyway. With the bigger space your fish will grow bigger and most likely faster which will create more load. of coarse this wont happen overnight...if you are exited to move em in i dont see an issue tho
If you didn't move the substrate over, expect a white bacterial bloom (heterotrophic bacteria) in the water column in about 1-2 weeks. The heterotrophic bacteria is responsible for consuming organic compounds, and in your old tank more than 60% of the organic compounds is found in the substrate.
This will not cause an ammonia spike nor a nitrite spike. I did the same thing from a 110g to a 240 g about 7 years ago.
Instant nitrogen cycle yes, instant established tank no. You could speed up the " establishment process" by introducing probiotic bacteria.

I haven't moved anything over. I'm letting the tank run while watching for leaks and fine tuning the bean animal overflow and pump.
Powder Rid-X. User about 1 tablespoon per 75g of water. Mix in a pitcher full of dechlorinated water, and let the particles settle to the bottom. Pour only the liquid into the tank. Make sure there is substrate and fish.
Lots of information about its use here https://www.monsterfishkeepers.com/forums/threads/the-use-of-probiotics-in-aquaculture.536531/
The surface area of your entire 75g tank and everything in it plus the 1500 filter is your current bio filter.
You are going to be loosing a good portion of your current bio filtration when you move just one part of the bio filter (the 1500 filter) to the new 200g tank. I would expect a mini-cycle to happen when you make the move to the new tank. I would plan on testing for ammonia and nitrites in the new tank after the move and plan on extra water changes if you detect high levels of these until the bacteria propagates itself throughout the new tank.
If you have substrate that you will be moving with the fish this will be beneficial since substrate generally has a large amount of surface area hence bacteria.
