Dear All,

My tank + my sump total around 400 liters. presently, my outflow is hook up with a filter but due to the clogging that always need to wash or change every other day has giving me so much inconveniences, so I have removed it but worry about those detritus will be creating pollution that may raise the NO3 and Po4 level as days go by. fyi, I have fight for quite a long time to reduce the said 2 nutirent level to a bit acceptable level.

Now my question is, since I have a feeling that my JNS SK2 is not enough , so I would like to buy another say smaller one that is hang on type in addition to the present sk2 skimmer. will this be advisable to do so? I understand you may say why dont I buy a bigger one, well due to the spaces area llocated, I dont think I can be able to fit a new bigger skimmer in my said present allocated spaces in my sump, so I opted to just adding another one.

Please advise.

Cheers,

MD

Tunze has a skimmer that is basically two 9016 skimmers bolted together -- so the concept works.

Next we have the plankton-safe series of Classic DOC skimmers. These rely on diffusion of protein laden

Adding another one should be fine.

thanks for your comment.

i am curious , In what way we can say that you got the right skimmer? by the level of the nutrients (say NO3, PO4) or simply by physically of those detritus being skimmed out? sorry, if this questions appear to be "out of topic".

Cheers,

MD

We don't have good ways to measure the effectiveness of skimmer in our systems, so generally, if the tank seems fine to you, the skimmer is acceptable, whatever it's doing. :)
