Retiring my old river tank and New River tank plans.
Moderator: LoachForumModerators
Chen- The acrylic is 3/8" thick and the tank is 16" high. The height of the tank determines the pressure that will be on the joints. It's Cell Cast Acrylic also, which is a very high grade compared to extruded acrylics.
I have a program for determining safety factors for aquariums.
The side seams on this tank have a safety factor of about 13. So that's 13x the strength that is actually needed before joint reaches failure.
The bottom seam has a safety factor of 5.6.
Most commercial aquariums only have a safety factor of around 3.
Enough talk. Time for me to fill the tank again.

Thanks all.
TC- The tank has center braces bolted in. They weren't bolted in during that pic because with them on I couldn't put the island in the tank. The tank does have 2" perimeter bracing also.
Update-
When filling the tank back up with water, to my surprise the island started floating when the tank was about half full. I put a few buckets of sand in the center of the island to weight it down (Thanks Bell for that great idea). I didn't have enough sand though, so I wedged some rocks between the island and the center braces.
Pics-


The tank is full now.

I ended up putting in the bucket quarters in each corner. It works and it was free.

I got the water pumps running now too.
This is turning out great. I'm so happy.
Here' a movie of the water flow-

I'll have More for you all later- I have a Texas Hold-em game to goto now.

The circular flow look perfect. Nice and fast at the backside too. You may never see your flow loving fishes again.
