Recently I bought a 112G (420L) tank and I was wondering if a filter that does 1000L per hour would be ok for it.
Thankyou in advance!!

I'd recommend a filter at least 4 times as strong, or a combination of 2 or 3 filters would be best for that tank.. you'd just want a total of 4200 LPH at least, if not more.

I'd recommend taking the Danios out and cycling using the fishless method. 2 Danios will die long before they help a tank that big cycle. You'll be able to cycle it faster without fish. Just turn the heaters in the tank to max and have the aeration running, then feed it with fish food or pure ammonia.
