Upgrading to a bigger tank - 45g tank to a 90g tank

Hello everyone,
I am getting ready to switch my fancy goldfish from a 45g tank to a 90g tank. I have an aqua clear 110 HOB on the 45g. I have a hydor professional 600 that I am using for the new tank. I also have a maxI jet water pump/ power head to sue if needed along with air stones. PH will be the same. Am I able to just move the aqua clear 110 over to the new tank and run it there for a few weeks or longer until the canister is ready to run on it’s own? Will I be able to immediately transfer the fish at the same time I move the filter over? The substrate will be brand new and I won’t be transferring over anything else at this time (like plants or decorations). Will my tank be instantly cycled this way?

thanks

 

I would, but keep a close eye on the water parameters, and you may want to ween the tank off the old filter, or move some old media into the new filter.

 

I upgraded from a 20 gallon to a 75. Moved HOB filter over and ran it in conjunction with canister for a few weeks. Moved all of the water and fish to new tank at the same time. No issues

 

Ok, thanks guys

 

I've successfully insta-cycled a number of tanks and I'd recommend 1. running the filter in an established tank for a couple weeks, but the longer the better and 2. I always move over some substrate (if this is an option for you) as that's the other place the little bacteria friends live. Typically for me it's Ecocomplete and I transfer over a small Tupperware container of it from my main tank and then backfill with new. If you're using a different substrate, you could probably move some and leave in the some sort of container and it might help. The key really is the filter though. The risk you run, though I've never had it happen, would be if the insta-cycle didn't take but I'd expect even if you get some ammonia or nitrite spike it should be muted compared to a standard cycle since you'll have at least some bacteria, just maybe not enough right at the outset.

Alright, thanks AW
I switched from gravel to black sand. I like the idea of putting some in a Tupperware container. I’ll keep an eye on levels and see how it goes
