Don't really understand your question. Is the weir in your sump or is the weir in your tank? If it is on your tank, I would not have any mechanical filtration as this might block and cause an overflow. The sump will do your mechanical filtration. If the weir is in your sump then it will depend on your filter media. Too fine will cause clogging and water level buildup, too coarse will let fine particles through.

I wanted to know if this would be enough to remove the floating debris in the tank as its only skimming water off the top. thanks :cloppy: Link to comment Share on other sites More sharing options...

Most of your heavier particles will sink and therefore will not get carried out unless you stir up the substrate periodically or you can always gravel clean them out. If you have a lot of this debris, you can always add a glass face plate in front of your weir which is open 10-15mm at the bottom. This will convert your weir into a bottom sucking drain. Alternatively, add a bubble wall (long airstone) along the base of your existing weir which will help to raise sinking particles up into the water column where they will be grabbed by the weir before they can sink again. This is assuming you have a heavy particle load. On a typical tropical community tank there is not that much debris produced. Link to comment Share on other sites More sharing options...
soulvdog Posted July 10, 2009 Author Report Share Posted July 10, 2009 Thanks, kinds what i thought but i just wanted to check. im getting my tank drilled today and hopefully some glass cut for the weir - thats if they have any black glass available Link to comment Share on other sites More sharing options...
RAR Posted July 12, 2009 Report Share Posted July 12, 2009 If you can't get black glass, you could try black perspex/acrilic. Much easier to drill. Link to comment Share on other sites More sharing options...
