Fish food and filter

Hi,
I bought 32lt new fish tank and i'm thinking to buy internal filter between aqua one mini 300f with 150 l/h or aqua one maxi 101F with 350l/h.
Is 350l/h too strong for 32lt fish tank?
Any recommendations good filter for my small tank?
I also want to buy online aqua one colour enhancer float pellets small (see picture) for my danios and white clouds. Does anyone know if danios and white clouds can eat that small pellets as they mouth so small..

Thank you for your help

350 l/h turnover is over 10 times the tank volume per hour so it would turn the tank into a whirlpool. The 300 f is the better choice for this tank - but don't bother with the carbon cartridge as carbon isn't needed. It looks as though it comes with a selection of outflow attachments - in a tank this size I'd go with the spray bar. And the photos look like there's flow speed regulator.
Or use a sponge filter powered by an air pump.


Just to make sure, you aren't intending to keep danios and white clouds in this tank are you?
