i just have a few quick questions about overflows,
am i right in saying that the air outlet tube on top of the inverted u part (that goes over the top of the tank) can be connected to a powerhead to remove any build up of air (and also make it start automatically once the powerhead starts)
also do i need one that can siphon 5x (or more) the amount of water in my system which is going to be roughly 100 uk gallons including the sump.
does anybody recommend a certain make/model, ive seen an aqua medic one which looks good but is around £180 (http://www.swelluk.com/aquarium/aqu...-overflow-boxes-type1-2-2500-5000lph-459.html)
and this schuran one (http://www.thecoralgarden.co.uk/pro...d=516&osCsid=6ce613907facc0a4ae9e23f0a3773836)
which is more than half the price, why is there such a big difference in price.
thats about it, thanks.
