Frequently Asked Questions
How do Sand Waterfalls work?
There are several different methods to create a SandFall. Our SandFalls use the suction created by running water to draw the sand into the main water line and create the waterfall effect. When the sand exists the nozzle it falls into the sand reservior where it then exits into the waterline again.
Are the materials in the SandFall safe for my aquarium?
AquaVista's Scapable SandFalls are primarily made from PETG. This is similar to the material that a common disposible water bottle is made from. PETG is considered safe by the FDA and is a recylclable material.
Do I need a seperate pump for my waterfall?
Maybe. Unless your model comes with a pump, you will need to either attach the input of the waterfall to the output of your cannister filter, a return pump from a sump, or you can use a dedicated pump. The SandFall will work with a range of pump sizes, but we find that around 400 to 500 gph works for most installations
Is there a temperature limit to the SandFall kit?
Yes, the material manufacturer rates the maximum operational temperature at 89.6 degrees F. Temperatures up to 122 degrees F for limited periods of time should have no significant impact on your waterfall.
What Type of Sand do you Recommend?
Our testing has been done with the White Sand from TopFin® Brand by Pet Smart and the Imaginarium® Brand by PetCo. We believe this sand has a suitably consistent grain size and gives the most realistic look. Sands with even some particles that are smaller in size may not work as well in teh AquaVista SandFall. Please test prior to use.
What is the Patent Pending Nozzle?
After testing over 50 different designs and combinations of SandFall components, AquaVista Aquatics has developed a Nozzle that reduces the output speed of the sand by allowing water to leave via one exit and then allowing the sand to fall from from the nozzle via another exit. Not only does this give a mroe realistic look to your SandFall, but by reducing the speed of the sand exiting the nozzle, you can more easily control the flow of the sand once it exits the nozzle. This allows for more consistent return of sand to the overflow, helping to insure longer continuous operaiton. We beleive this is a significant improvement to the SandFall technology and have applied for patent protection of this idea.
Why is there a grate at the bottom of the Reservoir?
The reservoir is designed to maximize the amount of sand that enters the SandFall while improving the operation and longevity of the SandFall. In addition, to preventing objects that are too large to pass easily thru the SandFall, the Grate design also helps to prevent backflow which can disrupt the proper flow of sand thru the unit.
Why use an AquaVista Aquatics SandFall instead of a DIY model?
- IT WORKS
- Reduces Installation Time by 50%
- It looks better due to the proprietary nozzle design
- IT CONTINUES TO WORK
First and foremost, IT WORKs. Our system has been heavily tested and works under a wide range of conditions. We offer detailed instructions and an extensive troubleshooting guide on our website. There are lots of videos and internet instructions on how to make DIY kits. What they don’t show you is how many times you will need to test and adjust your plumbing and your scape to get it to work. When you do get it to work, they frequently have a relatively poor rate of sand flow that is less than completely impressive. Once you finally have it working and then fill your tank for the final time and add fish, the DIY sandfalls will frequently either stop working or work even more poorly over time. And then what, rip your completed tank apart to start over.
In addition, The AquaVista Aquatics SandFalls use a proprietary nozzle design that allows the sand to fall out of the nozzle back into the reservoir. DIY versions typically propel the sand out at the same speed as the water and the sand bounces off your scape making it very difficult to get it all back into your holding area at the bottom, so it can be recycled back into the system. This means that your Sand fall will quickly run out of sand and stop working.
This system also includes a reservoir for the sand facilitating its complete return into the system. This reservoir contains a grate to prevent items that can clog the system from entering the plumping. It also reduces backflow, which can be another cause of sand being blown out of the system.
While we cannot guarantee you will never have a problem, we have tested over 50 different configurations and done numerous scapes with weeks of continuous operation. This has allowed us to design and build a very robust system that will help you build a great looking SandFall that will work for months and months to come. If and when you do encounter problems, our website has a great deal of trouble shooting information to get you back and running as fast and as easily as possible.
In our experience, creating a DIY SandFall takes a lot of time and effort. About half this time is getting the DIY SandFall to work properly and the other half is getting your aquascape to return the sand to the reservoir area and creating the look you want. Using the AquaVista SandFall allows you to eliminate the trial and error process of the DIY version and it also makes it easier to get the sand to return to the reservoir due to the proprietary nozzle. This allow you to spend your time on what you enjoy most, creating a spectacular aquascape that will look great and work for months and months to come.
