Canister Rec for 2ft tank

Hi all

I am trying to make a cherry shrimp tank

I have set up a shrimp tank laid with Gex Soil, and have some hornworts lying around and few meshes of mosses.

At the far ends corners of the tank, i put 2 sponge filter ( 1 left 1 right )

Livestocks include 3 cherry shrimps and about 10 albino guppy fries

Tank was running empty for about 1 week before i added live stocks.
Live stocks with tank running has been about 2 weeks.

I do not know if this set up is enough for keeping cherry shrimps in the long run. I am intending to add in about 30 more shrimps and remove the albino guppy fries.

Hence i am intending to get a canister filter. However, i have a budget about or less then $100 for my 2 ft tank

I have ATMAN canister filter in mind, however would like to ask if a ATMAN 1000 or a ATMAN 650 be more ideal ? I do not know if there's any ATMAN model inbetween atman 650 and 1000. If there is, please kindly recommend

Also, current ATMAN canister filter users, please kindly comment on the product. ( I.e. Very good filter, very quiet / noisy , long/short - lasting )

Please kindly comment if i should
1) Not get a canister filter, Not really needed for cherry shrimps

2) Get an ATMAN 650 because ATMAN 1000 is too strong

3) Get an ATMAN 1000 because ATMAN 650 is too weak

4) You should get other kind of canister filter !! ( Please recommend )
