Below are the original containers I planned to use for the filters. The others haven't arrived yet. The pvc pipe is larger in the interior than I anticipated so likely the t-joints won't be used...I'd have to go down to a 3/4" likely to make it work which wouldn't stabilize the powerhead. I can still use those pieces to make small caves.
I'm going to run a test on these to see if I even need the pipe since this would be a closed system. I used pipe before to mostly stabilize the powerhead seated up top. These would be open at the top anyway so heavy media could hold the powerhead. Gonna have to play with it a bit. Because these walls are solid I'd have to prime the vases them by filling with water first. Since the assembly would be submerged this would only need to be done once.
With the other design with openings in the walls I will also test to see if the pipe is necessary. Whichever design has the better flow I will go with. The pipe will be drilled in any case.
I'm also looking into if stainless steel is safe in freshwater aquariums. Reason being there are perforated pipes available in stainless steel. Such pieces are used in filter parts. Not sure if a larger scale use would work.
Comparison size to a standard coffee mug. Each vase holds 2.1 gallons volume. As recycled glass they are pretty cheap!
