Will this DIY overflow work....

[rockfish]

please go look into your skimmer column and see what is the water level inside that......

sigh... again...

hi porc!! sigH u back..

that min water lever is for it to maintain the siphon when the water is not overflowing into the tube ... that is in case the pump stop ... dun need to reprime the system ... read the thread properly beore u sigh ... sighing kill a million cell in u each time .. save ur sighing for more important things ..

Hey bro rockfish,

Thank you for your strong reply... got me thinking again why we are having so different opinions on the designs... I realised that maybe our assumptions may have been different in the first place...

My assumption is based on an overdesign in the piping sizes... so bigger pipes, less friction, less pressure difference required. so not neccessary to lower the second bend.

This assumption might not be there in your recommended design, so with a higher flowrate with same or smaller piping, yes you do require more pressure difference, which you would then need more height in your tank for the equilibrium tank level to be achieved if you simply use the design given by bro domino, or to use the skimmer tube as you mention...

Could you share with me your experience in using the earlier design? When you say that you find the flowrate slow, has the equilibrium tank level been achieved yet? or is it that you find the water levels still increasing but the siphon is still unable to cope with the flow so you decided to stop before your main tank overflows?

Cheers...
