Substrate Slope?

[tokyo]

How do you achieve a sloped substrate?

I've tried building up a regular sand or gravel substrate to create a slope but it always levels out.

Here is an example of what I mean:



I would actually prefer it to be slightly steeper if at all possible.

You could use something to stabilize the slope, like eggcrate or screen... For example, in my newt tank, there is a rather steep slope from the water portion to the land portion. I have used gravel as the substrate and it is what makes the slope. I have a piece of screen on the slope to minimize erosion, and moss has grown down the screen and into the water, further stabilizing the slope.

That's a gorgeous tank you used as an example. Thanks for that one, I'll have to dream up something similar sometime soon.

WOW, can you send a link to where you found that picture...Super nice tank!

Grimm, click on the pic, it takes you to the site. I think I've seen that one before, but I'm sure glad for the refresher.

Yeah, I was very impressed with this one. Its made by a company that builds exhibits.

I can't figure out how they got the slope to work so well. It doesn't look like there is any support under it.

I will have to try your screen idea. Maybe use a large gravel as a base, maybe mixed with aqua-soil, then put the screen down and cover with sand(or more aqua-soil?).

I would just be worried about the screen becoming visible if the aquatic life decided to dig along the shore. Maybe if I built up the soil enough it wouldn't be an issue.

Its too bad the link doesnt show any pics during the build. The substrate is said to be aquarium soil. Im sure the soil sticks to itself better then gravel would. Also, the large rocks will help keep the slope in place.

If you want some unexperienced advice then maybe try this out.....Maybe place 1-3 pieces of plexi, plastic, or glass vertically at different heights. Drill holes in each piece to allow water flow, and silicone them in place.

Or you could run mesh the length of the tank, and silicone the ends to the glass. This would be the best method to ensure water flow, yet still act as a retaining wall.

Im just throwing ideas out there so they may work, or may not.

Thanks for the ideas. I would like to avoid modifying the tank if I can.

I'm e-mailing AFA to see if they have any suggestions.

Perhaps the company that built it could give you some advice. I remember seeing this while going through those old contest entries, and it is a stunner.

I e-mailed the company a couple days ago, but so far no response.

For a gentle slope like the one in the picture, you probably wouldn't have to have any support. If you want to go steeper, like you said, you'll definitely need it then.
