go to Lowe's get some acrylic and some Popsicle sticks or something along the lines of that glue the sticks to the top of the acrylic and just drape it into the tank and you have very cheap tank dividers
I was looking at the PVC piping at Home Depot today, I think it could work for the plan I have atm. Would it be safe to use the metal elbow's also available? A employee told me they would be 100% safe in an aquarium, no leaching into the water or anything. Is this peice recommended, or should I be looking for some kind of plastic elbow instead?Several years ago I created a frame out of 3 1/4" PVC pipes and 2 elbows that I put together in an up-side-down U shape. You can cut them easily with a hacksaw. Then I zip-tied some mesh to the frame. Pick the mesh that's appropriate for your sized fish and allows water to flow freely. I stuck the two upright pipes into the gravel and it worked like a charm. It was very sturdy too, keeping two angry adult Severums apart. Oh yeah, cut a notch or two in the top pipe to keep the whole thing from floating.
What I saw at Home Depot was more of a white/blueish colour, and was recommended the metal elbow's they had available. Are these what I should be using, or would the PVC elbows be the same colour and material?Any place that sells PVC piping sells PVC fittings too, including elbows. Those are what you should use. This is referring to the white PVC, not the blue gray PVC, which some stores also carry, but which has much fewer fittings for. Those also work fine in an aquarium and are darker, so less visible in the tank, but it can be a problem to find the fittings you need. Then, there is cream colored CPVC piping, carried by some stores, which is smaller in diameter, and also has fewer fittings available. It also works fine in aquariums, and the smaller diameters make it a good choice for spray bars, etc.
