Well, here is what I was thinking for the Siphon Surge project:
Here is the exact drawing of my tank.
First off, I was thinking of doing a Coast to Coast over top tank, dimensions would be 96" x 6" x 8" 20 gals total capacity (Full Volume).
Some of the reasons I thought about doing it like this are:
1. Weight is more dispersed as it will be on top of the main DT (It will weight around 150lbs with the amount of water it will hold before siphoning)
2. It allows me to place two Siphon Surges at each end so better distribution of water
3. It's not too intrusive so light won't be affected or tank maintenance.
4. It doesn't cross or bother with my external overflow where the Dursos that go into the sump are right now.
Here is the picture with the New Overtop tank colored in yellow:
As you can see, the Return line coming in from the sump (Right one) goes through the lower overflow (As it is right now) and then into the Siphon Surge Tank.
The Left one is the overflow from the Siphon Surge in case either of the surges gets stock, water would still be able to exit into the lower overflow, preventing a mess around
Here is the Left and Right Dursos for Siphoning water into the tank, I'm using 1" Dursos:
And a full render of the tank with the Siphon Surge implemented:
What do you think?
