NEW Tank Build !!!

[lastlight]

you don't need dursos really. the full siphon can just be thru bulkhead. i tune the flow so it just barely trickles into the secondary standpipe. You make the standpipe / emergency drain taller to raise the water level in the overflow box and make it as quiet as possible.

so the emergency also allows you to balance the height of the water in the tank?

[lastlight]

the height of water in the overflow box. the standpipe/emergency should still be a bit lower than the overflow weir / cutout so you don't raise the display's levels.

my cut outs give too much gap between euro brace and water height thats why I asked, instead of closing off the depth of the teeth I thought it would be easier just to raise the standpipe?

I need to raise the tank level basically

[lastlight]

i guess you could but would that scenario skim the surface as well? i'd personally silicone a strip of glass inside the overflow to raise it up a little. it could be glued behind the existing teeth.

argh yes you are right, time to get the silicon gun out

Brilliant help thanks.

How much gap you guys leave from water height to Euro Brace? I dont like seeing much of a gap but also need room for turbulence.
