im thinking of putting in a new weir in the tank i dont want to do the normal L shape id like to use on flat piece of plexi so it makes a triangle but im not shure id i want teeth or not any pros and cons of using teeth or not to use teeth also another reason is i want to put in 2 stockman stand pipes or just use 1" tees in the back there is 2 - 1" drains and there is just not enough room for tees and/or stockmans i figured if i want withthe flat piece fo plexi i can get this to work

will 3/8 5/8 or 1/4 be ok for the weir

thanks

weir? I take it that to mean a internal overflow... I actually recommend no teeth, but put some plastic grid or some such to catch small fish instead... that's what Terry and myself both do. Do durso standpipes, I tried stockmans, but they're finicky and a lot tougher to make... dursos don't take up that much more room. Check out the thread about my 240G in alabama reefkeepers area, there's information about all of that.

According to www.dictionary.com: a weir is "a long notch with a horizontal edge, as in the top of a vertical plate or plank, through which water flows" and "a dam placed across a river or canal to raise or divert the water, as for a millrace, or to regulate or measure the flow".

I'm mostly familiar with it as an engineering term referring to a "hold up" plate in an extraction or stripping column. The weir the wall of a tray (dish) that holds liquid to a specific height.

Sorry... couldn't resist the temptation to straighten out an engineering phrase...

I've had both the toothed and the flat... I think the flat with a "strainer" is the quietest type.
