Does your rock sit on your substrate ?

[Brimc]

I am setting up my new tank and have read that your rock should be off your substrate for better flow and ditrus removal. I wanted to see how many people if any used Plexi under your substrate and used plastic rods to lift your rock off the substrate and how many went old school and placed their rock directly on the substrate.

when i did my tank i put about 3in of sand down then i put the rock down onto the glass,wiggled it in the sand until it touched the glass then i put the rest of my sand down 2-3 inches.

I put my rocks directly on the glass and then added the sand, about 2-3 inches.

My rock sits on egg crate,then the sand.

My rock sits on egg crate,then the sand.

that's what my next tank will be...

right now rock sits on glass, and substrate is around it... like the others said.

Sit on glass then added sand.

eggcrate, came with my new tank so i figured i'd go with it. 3 days in and no problems

sits on the sand....i was told if you can to try to create a space between the sand and the rock so detrius and excess food doesn't get built up around the base of the rock and create water chemistry problems...

I put the eggcrate down and covered it with enough sand to fill in the holes then added the rock then the rest of the sand.

my rocks started out on the sand, but my PITA shrimp goby got them down onto the glass....

I use an acrylic rod lift system and have a spraybar at the back of the tank that shoots under the rock as well as up the back wall of the tank.

My rocks sit on bubble wrap and each other at the moment. But they will be sitting on a ghetto, homemade version of an acrylic rod lift system.

Mine sit on an eggcrate base under the sandbed for stability, but are directly in the sand.

My rock is attached to acrylic sheets via rods and silicone. This system them sits directly on the bottom of the tank. The sand is then around the rocks.

This system was done for my love of engineer gobies

On eggcrate, in the sand.

 

[bigdog]

on the glass then sand around

 

[Greg Hiller]

Rock on the glass bottom. Sand added around it.

I also use an acrylic rod system. I took three sheets of 3/16" acrylic, drilled 1/2" holes 1/8" deep on a 2.5" x 2.5" grid pattern. I then cut a bunch of 1.25" pieces of 1/2"dia rod, drilled the end with a 1/2" bit just so the cut reached the edge of the rod and then ground notches around the circumference (so it looked like a little crown). This affords excellent grip on irregular shaped rock. The undrilled end was then WeldOn'd into the holes in the sheet.

I did three separate sheets so I could move them around a little. The rocks are held high enough for detritus eaters to get at everything in the subsrate and the rock work is solid.
