My 72 gallon bowfront rebuild build. Fresh or Salt?

I'm going to install some comp. fans into my canopy to blow the hot air out.

 

Thanks Corailline.

 

There cheap and appears to be effective.

 

Tank is looking very nice. Thanks for sharing the video!

 

Awesome tank and video. Thanks for sharing!

 

Thanks! I am happy to show off my tank

 

very nice. Relaxing looking.

 

Thanks! So I got the 15g sump in the stand, just filled it up and became concerned, when I had the 20g sump under the 40b the available capacity in the 20g would handle all the back flow in a power outage or mechanical failure until the back flow was broken. This 15g has perhaps 3g capacity before it would overflow and I am certain it will not be enough to hold what would back flow out of the 72g before the siphon would be broke.
Things that make us go hhmmmm!! Time to put on the thinking cap.

 

I think someone is trying to tell me something! Just now I watched as my clowns are starting to form a relationship with my Bubble Tip. Awesome!!

 

So this is what I got to work with, I don't think it was leaking from the bulkhead, but once it leaks its hard to be sure where its coming from when the water works its way down the entire plumping. Plastic tubing and PVC elbows.
