    Hi guys ive got a major algae problem,my tank is running with skimmer 1st compartment and np in the last before returning to my tank from the sump.Is that maybe a cause should I put the skimmer after the np reactor?

    NP reactor is correct in the last chamber, the return from here should go directly to your skimmer to remove excess bacteria

    Biopellet reactor should be BEFORE skimmer. It is fine for it to be in last compartment, but its outlet should be plumbed to be before the skimmer intake.

    The degree of blame for your algae problem is questionable, I would suspect more of a contributionary role.
    I would rather evaluate the overall system and husbandry techniques instead of jumping to conclusions, clutching at straws.....

    Post some pics of your setup or a link to it if you have a thread on here somewhere. This will enable us to assist in finding likely causes.

    good advice given, be careful of treating the symptom, rather try find the cause and take it from there..

    my view on carbon dosing products is that they should be there soley as an extra and not a dependable.. they are there to polish off a already well running system and not a quick fix for problems..

    good husbandry is the key element to any problem..

    NP reactor setup is a bit of a problem. You want the inlet to the reactor to be as far away as possible from detritus. Or anything else that could block up inside the reactor. Actually the same as all other reactors.
    But you want the outlet to be in front of the skimmer, so that the bacteria scraped off due to the pellet movements are immediatly skimmed out.
    Normal sump layouts are Mechanical - Biological - Chemical. But NP-reactor give off a lot of bacteria that you must treat again as quickly as possible.

    If you can it would be even better if you could plumb the reactor outlet into the skimmer inlet using a T joint. That way all the reactor water passes through the skimmer and the skimmer pump can still pull extra water from the sump as needed.

    Cool idea but take into account different pump ratings. You do not want to starve the skimmer pump and you cannot either pushed too much water through the NP-Reactor.

    Skimmer should be able to pull in extra water from first chamber.

    Two things duanhead

    Firstly if you have a new system i can gaurantee you are experiancing problems due to using to much biopellets to early on.

    Secondly The SM161 skimmer you are using is way to small for your tank

    That is why he said a T and not an elbow. ;)
    I did this and it worked pretty well.

    the purpose of the T is merely for allowing a fixing point for the NP reactor effluent to be delivered closely to the intake pump of the skimmer .. it could be a 50mm T with a reducer to allow better attachment to the pump and unrestricted feed to the pump..
