    Hi all, It will for shrimplets. Usually they will live quite happily in the filter, you just need to make sure that you don't pour them down the sink when you clean the filter. I'm not sure that this is a viable option with a filter with a pre-filter. Personally I like a sponge filter with...

    Major shrimp deaths, feeling like giving them up :(

    Hi all, The high pH is almost certainly because of sodium hydroxide (NaOH) injection.
