Go back a few posts.
If you have a DURSO...you have a hole. Therefore you have an air injection zone, therefore you have noise.
My system has NO noise. NO NOISE.
The spare residual overflow will take a hell of lot of extra water if required.
I have it set up in such a way the I can pull the whole 32mm unit out of the bulkhead if I am to go away for holidays, thus back to full exit from the 32mm overflow with no restrictions.
Suphew, i am not even talking about a DuRSO here. I have gone past that. If you like your durso, you keep using it. If you saw my system in operation you would see how safe it is.
I want NO noise, i live in the country and 8000LPH will make a shitload of noise if not done correctly.
I messed with the DURSO system for about 6 hours before realising I could not acheive what I WANTED WITH IT.
sO i SIMPLY CREATED A BETTER SYSTEM. Even this may be "Bettered" yet.
