Super Easy DIY Surface Divider (for floating plants)

So I've been having so much trouble keeping floating plants alive. My filters do such a nice job circulating the water that they create a lot of surface agitation. The floaters then get pushed all over and finally get pushed down into the water and usually get sucked against or into the filter. I actually had not been able to keep even duckweed alive in that tank!

I did a quick search for an easy aquarium divider that only went down the first 2 inches or so of the surface to prevent one side of the tank from getting so agitated. To make a dead spot, so to speak. I still wanted all my filtration power but didn't want to lose my floaters. I had this idea after watching my bacopa get so tall that it cut off one side of the tank from the filter outputs. The side that was cut off was almost perfectly still on the surface. My duckweed finally had a nice spot and was somewhat recovering. Then I did a trim and lost my "divider."

The idea to use plastic canvas (this stuff) and suction cups came from someone else. I don't remember where I saw it, but it was on a google search hit. Anyway, all you need is a pair of scissors, some plastic canvas (found in the craft supplies, usually by the yarn), about 4 or so suction cups (I used the 1 inch diameter ones), and some fishing line.

The plastic canvas came in a package of, I think, 10 sheets of just slightly bigger than a piece of printer paper. This was not quite big enough to reach all the way from the front of the tank to the back. This is where the fishing line comes in. I took one sheet and held it to the side of the tank. Then I marked on the tank (using chalk) where it came to. Then I re-measured from that spot to the back of the tank. Then I marked the spot on the canvas where I would need to cut. There is no need to mark a line for a straight cut as the grid is already a nice line to go by. Anyway, I ended up with about a 13" by 2" piece and another approximately 5" by 2" piece to make the front to back strip. You should make it just slightly shorter than the distance of the front to back to accomodate the suction cups. I then used the fishing line to "sew" them together. I tied a not to hold the 2 pieces together at the top and then threaded through the holes to the bottom and back up again where I tied another knot to keep it all together.

Then I attached the suction cups to the canvas using the metal hooks that were already attached to the suction cups. I did not close the hooks yet, but I do recommend doing so to prevent the suction cups from becoming detached from the canvas. You could also attach it using fishing line if you wanted, just remove the hooks first.

I took pics and a short video to demonstrate how to do this and how well it works. I need to upload them yet, and I want to remove the audio from the video also (camera makes an annoying sound when recording, ugh.) So, it will be tomorrow for pics and asap for video. In the video I dropped in fish food so that you could better see the action of the current from the filter outputs.
 
Cool, I'll have to try this since I've absolutely failed at keeping frogbit and floating ferns.
 
I might try covering it with java moss or bark or something so it doesn't look so completely artificial.
 
Lol, I just remembered that I was going to post that, but you beat me to it!

I'd just be careful to keep it wet or the plants might struggle or die. Maybe something that's sort of borderline so that it could handle both wet and dry periods. Hmm, wonder what would work for that...
 
Here's the promised pics. I included a close up of the outside where the divider is, a sort of top/side view, and a whole-tank view. If you look closely, you can see the suction cups. Sorry for the muddiness of the water, I had everything stirred up when I was rearranging the plants and stuff. Plus, my driftwood is leaking tannins, I guess. Didn't realize how yellow the water was until I go the new light.

I'll probably take a supplies pic also and maybe do a better step-by-step instruction. I'm hoping to be able to work on the video tomorrow night, but no promises.

EDIT: I'm also planning on weaving moss or tying moss to the canvas to mask it, but that will be some time as I need to find a source for a large amount (and the money, lol).

'Nother update: I just paid for a winning bid on a bunch of Java moss, so hopefully it will be here by the end of the week and can be tied to the canvas. I did a quick search, also, and it apparently does okay outside the water as long as it is kept moist. So, I think it will be okay even with the top occasionally being out of the water due to evaporation. We'll see.
 
i love this mesh, it's crazy how many uses I've found for it. They also sell a black version of the mesh, which should blend in better. I'm definitely looking into trying this. Up till now I've been using a breeding trap anchored by a mag float as a little floater haven. Thanks for the idea :)
