Ok, apparently I didn't click the "watch this thread" button :lol: Sorry for the delay in responses
A few things... To do this and do it right is going to take a lot of work and a little $$ The work I'm not afraid of... the money... well it comes and goes.
Chefkeiths tanks are xactly where I got the idea from. The only difference is I'm not experienced in creating things out of plexi-glass and would be afraid of failure....
And yes, of course all of the tops of the tanks would have to be level with each other, that's not a problem, I own a few levels
As far as waterflow is concerned... I'll be putting a small pump in the corner of the 800 to pump water to the 240, which will then let water flow through the bridges back to the 800. I've tested this in my smaller tanks in the back room, it works well :thumb:
I got a good idea from someone on another forum for keeping them clean. When i build them I'll build in magnet cleaners! I don't see why that wouldn't work???
Here's where the tanks would eventually go:
Keep in mind that the 800 is 12' from the 240. So if the 265 was set up in the middle I'd need 30" of clear pipe on each side. Which is perfect because I found this:

They sell 6" pipe in 5' lengths :thumb: Get one and cut it in half! Then I'd get 6" 90's locally and a stick of 6" regular pvc locally. The total would run around $235 for two water bridges.
The thing is... I've got to wait till spring to repair the 265 as the basement is now a play room... :? Stinkin kids :lol: By the time spring rolls around they won't want to be inside which will open up that room to do the work... problem is.... I get very busy in spring :x I have no clue when I'm going to get this done!!!!
Here's some pics of the 265, he gave me the bulkheads with it too

:
The back's been spray painted black, so all that spray paint needs to be scraped off. Then the plan is to take 3/4" plywood and pain four coats of drylok on all edges and both sides and silicone it to the outside. Running beads of silicone over all the cracks and well.... every where :lol:
Then I'll take a piece of hardi panel, the same material used to line the 800 and paint four coats of drylok on that too, then silicone the shnot out of it to the inside of the tank. Sandwiching the broken pane of glass inside. In theory... it should work :lol:
I forgot to mention that since I can drain 1/3 of the water out of the 800 by turning a valve... because of the water bridges the water should drain down on the other two smaller tanks too... So the whole system can get a water change at one time :thumb:
I'm even considering not even building a filter for the 265. Between the massive filter on the 240 and the incredibly massive filter on the 800 there shouldn't even be a need for a filter on the 265... I'd like to hear opinions on that.... Also I'd still put ugj's in the 265...
