    Hi. I have a 16 gallon tank with an Aquaclear 20. It has 6 platies and 4 amano shrimp. I do 25% PWC weekly and the parameters are good (ammonia 0, Nitrite 0, nitrate 5-10). I would like to add some more amano shrimp but am concerned that I am underfiltered. I was thinking of getting an Aquaclear 30. Question is should I replace the Aquaclear 20 (and put the sponge and biofilter media in the new filter) or keep the Aquaclear 20 and just add the Aquaclear 30 as a second filter? Any thoughts would be greatly appreciated.

    Aquaclear 20 is 100 gph, aquaclear 30 is 150 gph. Each can be deceased to 1/3 of the max flow rate.

    are you sure its 100 GPH and not litre per hour?if so,no need to change your filtration.Shrimp doesnt produce much waste anyway.

    If it was a shrimp only tank I wouldn't worry about it. I also have 6 platys in it.

    vasyat I think the point Axel was trying to make was that you can almost discount the shrimp and just look at the Platys. Unless you are planing to add more. that filter should be fine. However it never hurts to have more filtration assuming the water flow isn't too much for the fish. Although IMO I think running both of them may be a little overkill...
