Can I do that even though my numbers for the 10 gallon tank are all screwed up ? And I added pure ammonia to the 29 gallon in the morning
So the ten was cycled and since you added the fish your getting ammonia again??? That is a mini cycle from adding fish too fast. You will need to check your params daily and do PWC if needed until ammonia and nitrite are 0 again.
This is what I would do if I was in your situation. Someone else might have a different opinion.
Do a 100% PWC on the 29 to remove ALL the ammonia.
Move all the fish, decor, some gravel (as much as you can get in a media bag) and the filter from the 10 to the 29.
Run both filters on the 29.
Check the levels on the 29 daily and do PWC if needed (amm or trite over 0.25ppm).
Once the mini cycle is over, wait two weeks (enough time to seed the 29s filter) before moving the 10g filter, the ember tetras and the gravel/decor back to the 10.
Check params often to make sure both tanks aren't mini cycling again. Do PWC as needed.
Stock both tanks slowly once params ate stable.
The reason I suggested this is because it is easier to keep the water parameters stable in the 29 than the 10 during a cycle.
