Canister to sump questions

[AngiGiles]

We got a 5yr established 75g tank about 5mo ago, just set up a sump finally. There's pretty much nothing in the sump, a filter sock a couple small rocks and some filter media between the baffles. My question is, can I just remove the canister now? Wait a week? I mean there's nothing to "seed" but it feels weird just taking it off.

Question 2, that canister is going on a 29g, that has been cycling with all new sand/dry rock for a little over a week, added about 2oz of Dr Tim's on day 1 and another 2oz on day 5 and prime every day... is it safe to assume adding that canister would instantly cycle that tank?? The tank reads no ammonia/nitrites and about 10 nitrates.

Thanks for any help/advice

Why would you use a canister on a tank that's ready for a sump?

The canister is what the 75g has been running on for 5yrs, we added the sump yesterday, now I'd like to move the 5yr old canister to a new 29gal. We currently have the canister still running alongside the new sump

you should be ready to just move over, assuming that the tank has enough rockwork to hold bacteria in it, and not relying on media in the cannister for the bacteria

Why not place the canister biomedia in the sump for at least a bit?

If you have functional live rock in the 75, the canister is a little more than a water pump at this point and could easily be moved over to the 29.

I'd like to use it on the 29g. We ended up with a "surprise" scorpion fish that I'm dying to get in his own tank! I just don't want to jeopardize the 75g trying to hurry things along.
