please recommend which Tunze internal skimmer I should buy

I am setting up a 200 liters marine tank but unfortunately I cannot have a sum. Looking for an internal skimmer to put inside the tank. Could Tunze representative recommend me which model I should buy? Since tank will be in bedroom so ideally a quiet model would be preferred.

The 9004 is the smaller version of 9012 and the best suited for a tank this size.

Thanks mate. However if I use larger upcoming 9012 instead would it be ok for my small tank? I was told the larger skimmer possible the better, or is it not true if I use too bigger size the skimmer actually wont perform well then?

With too large of a skimmer, their often is not enough waste to build a foam head and skim anything. It is better to get a skimmer that is the right size, slightly too large is one thing but more than double what you need it will likely not skim consistently.

I am just worried 9004 is not sufficient. What if I use two 9004 would that work?

The 9004 is rated for a 150L tank with a mixed reef population, the 9012 is rated for a 750l tank with a mixed reef population. The problem with 2 skimmers is it is never the same as one big skimmer, the basically fight over the same organics and one tends to win and usually they alternate so only one has a foam column at a time. It can work, but it is not perfect, it is more like adding 25-50% performance, not doubling it. The 9012 is not out of the question, but if the organic load is low, it may not perform much at all. It would be better though to go with the 9012 over 2 9004's from a practical standpoint of cost, footprint and just value for the money. The biggest factor will be the intended load, if it was all SPS and heavily stocked and fed, the 9012 is definitely the better choice.

Hi Roger, thank you so much for your time to explain to me. I think I know what to do now.
