I bought a new hole saw and I am going to bottom drill the custom-built 75g acrylic tank. I'm gluing up the plumbing and preparing to measure and drill.

I'll post some photos in my thread called Plannimg First big DIY Systems.

Thanks to all the members who gave me their opinions and ideas. That's why I really come here. It's not all just about me showing off. Really, I promise, it's not. ;)

Backfromthedead Backfromthedead Yes, that's the idea, but a little too robotic looking for me. I'm going to build something on the same principal. Open drain, return line and throttled drain in some big plastic mushroom looking thing from PVC.
Well that didn't work out with my plans, and the pre-made thing was so expensive and ugly I could not justify it.

I'm just going to run an ordinary return line up through the canopy. I made a drain so large it's never going to clog. :)

( I probably just jinxed myself.)

pacu mom pacu mom That sounds really interesting but I still can't quite figure out how your filtration connects to all those pipes. You must have a lot of hoses or some large manifold with lots of clamps or unions.
We haven't been able to set up the big tank due to family illness which keeps me away from home and unable to complete the backgrounds. Here's a pic of the little 300 gallon tank. On the right are two poop sucker pipes with a return line from the FX5 with UV sterilizer taped to the PVC. The mechanical filtration return comes up through the overflow box seen on the left. There is a third poop sucker pipe at the far end of the tank, and the return from the wet/dry filter is on that end.

On the big tank, the poop sucker uptakes will be connected similarly with valves on each uptake (in case we break a bulkhead or pipe). The returns will also be coming down from the top of the tank, so it will get pretty crowded up there. The biggest problem with all the pipes up there is that I will have difficulty climbing down into the tank. Can't really put the pipes on the back of the tank, as we have external overflow boxes there. There will be a lot of plumbing. It will be pretty busy inside the tank with the eight returns from the sump and the eleven pipes.

I know what I want, it just has to be executed.

The paint looks great. Did you use acrylic paint?

Yes, but I messed up the clear epoxy sealer and have to roughen the whole thing up and try again. I had a lot of orange peeling, and took a dremel to every little pit and divot. I had contamination (epoxy dust). Actually, I hired an artist to paint the panels, but with the distortion, etc., I essentially had to repaint the backgrounds. I was horrified after we installed the panels to discover that my repair repainting was too blue. I joined all the seams for a seamless background on the sides and back of the tank. I repainted half of the background numerous times before I was satisfied with it. Project is on hold while I deal with family illness.

Off-hand I'd say about half of those things are not exclusive to bottom drilled tanks, by any means.

Also I cannot think of a single thing supporting that statement that the filters will last longer
The filter will last longer because there is less energy required to pump the water into the tank and no one is debating how many of the reasons applies to tanks that are not drilled.
