    Hi All

    Im currently plumbing my 2m tank and found out the previous owner had his overflow section basically split like a mini sump.

    The water would overflow down through looks like 1-1.5cm stones then come out at the bottom and enter the exit chamber.

    Question is should I rather remove these stones as I believe it would slow down the circulation and also trap all the gunk from the display tank eventually making it a nitrate factory

    debris needs to be caught somewhere IMO.. if you remove the stones and clean that compartment often it can actually be beneficial as the debris will collect there and not on your live rock or sand bed

    I think the stones were added to lower the noise level of water falling into the overflow.

    What prevents the water from falling directly down the bigger right hand chamber?

    I think the previous owner might have filled this compartment with seachem matrix not a bad idea but dont know if i could use this with red sea nopox.

    ok. that makes a bit more sense.

    What is the brace directly above the overflow? I can make out the flexible hose above that. So what was the water level in the tank. The big black trim around the top of the tank, was the water level at the bottom part of that?

    A picture from the left side, standing next to the tank, but do not zoom in on the overflow.

    Anyway, from what I get, The outlet is too small. And the net will become dirty and block up, forcing water to go over directly into the bigger chamber.

    It does seem that the tank got a lot of waster water volume, due to the height of the overflow being at the bottom of that black trim. But yeah, another picture will confirm that. 50L or even more. Raising your water level by 10cm and you add about 90L to that system.

    overflow is way too small
    Can you take another pic from same side, but further away. Do not zoom in on the overflow box. Need to see the tank top edge and overflow in the same picture. What is that brace on top of the overflow? Does it run all the way to the other side? Is that brace at the very top of the tank? Does not look like it.

    I would leave it or change it with ceramics , but on top put some sort of filter mat so it cathes the gunk. Then you can have a nice co pod collection growing there.
