So you are transferring all the fish from the 20 gallon into the 75? Are you adding any more, or just what was in that tank? If you don't allow any of the bacteria to die by drying up, you should be fine. The filter from the 20 is a good idea. The gravel will also help.

Have you added many plants to the 75? Once they start growing they will be taking in the ammonia as well. If your plant load is med-high and your fish load is low-med the plants might do all the biological filtration for you.

The 20 will be emptied of everything and setup as a breeding tank for snails and shrimps to be used as food.

I'm putting 2 senegal birchirs and 2 clown loaches into the 75. I'll add another clown loach in a few weeks when its completely stabilized. Then wait a few weeks and add some more fish, thinking Severum, Festivum, and an Angelfish.

The plants from the 20 will go into the 75. I'll be going by Petsmart on tuesday to purchase some more plants.

What will cause the bacteria to grow in the cannister if there is enough in the Penguin?

I planned on putting the Penguin back on the 20 but I'm afraid the 75 will cycle with its removal. I might just keep the Penguin on the 75 and buy another small filter for the 20. Then when I'm ready to set the 20 back up put the media into it.
 
What will happen, I'm pretty sure, is the bacteria will start to grow on the new gravel and the canister filter. If you wait a few weeks, you shouldn't have to worry when removing the Penguin filter. Especially if you have a decent amount of plants by that time.
 
okay the 75 has been up and running since Sunday. I put the Penguin on from the 20 running with the XP3.

So far everything looks good, but the 55 looked good for the 1st 3 days too. I'll keep you guys up to date.

I'll get pics up soon.
 
Day 4

AM 0
NI .25

There seemed to be a good amount of food caught between the rocks so I'm assuming this is the cause. I've moved them apart some so the fish can get to them.

Water change done today.
 
Days 5-9 NI was still .25

Added Prime to help detoxify nitrites to fish.

Added Stress Zyme to help, lol, with biological bacteria. Doubt it will help but couldn't hurt right?

Will test later to check NI

edit: NI under .25

water change again

I can't age my water, no room, and my PH straight from the tap is 6 if i'm lucky. After doing daily 50% water changes and checking the Ph I noticed the PH wasn't rebounding as high, PH was 6.4 or so. This concerned me as it was going to be up and down to much for my taste, or keep dropping because by the time it degassed I was changing another 50% which would drop it lower. I switched to 25% water changes,after skipping a day to let the Ph get back to normal, this has helped keep the Ph around 6.8 which is normal.
