liner for under rock scape?

[clarimore]

anyone ever put a liner on the bottom of your tank to set the aqua scape on? I'm setting up a 180 with the stuff from my 90 plus more rocks.. I feel like I need something like pool liner to keep any of the rocks from putting too much pressure on a small pressure point somewhere...?

Nope - just sand.

HDPE or acrylic sheet. A little pricey, but I'd never put rock on glass, or any significant amount of rock on top of sand.

I have been using these on all my new builds from now on. I wish I put them in all my already running builds.

24" x 24" Black ABS Plastic Sheet

An Absolute Must For All Bare-Bottom Aquariums Overall Dimensions - 23 3/4" x 23 3/4" x 1/8" Bare Bottom tanks have been around for a long time, and come with a lot of benefits, but they leave the bottom of your tank unprotected, and depending on the aquarium it may not be very appealing...

You can also get 2'x2' or 2'x4' extruded PVC ceiling tiles in white or black or even textured in either of those colors for $7 or $15/sheet.
I haven't tried it yet though...

Yup! I used starboard

with engineer goby that is 12+ inches long.. I set my rocks right on the glass not on the sand. ? you thinkn im being silly worrying about a sharp edge making a pressure point?

Dropping rock on glass or the aesthetics are the only real concerns. The weight of the water will be significantly more than what rocks will put on it.

Sure the ABS plastic will certainly help distribute the weight some.

Not at all. I put sand down in my tanks and then rocks on the sand, but most of my aquascape consists of marco shelf rock.

Rocks first, then sand.
Reason:
That goby digs under a rock that's on sand. Rock is now not stable and tumbles. BAD. Bad for the fish, bad for the tank if it hits the wall.
Same scenario, but rocks went in first, sand second.
Goby digs under rock. Goby hits rock or goes around rock. Rock still is stable. Good for the goby, good for the tank.

If worried about stacking rocks straight on the glass,then watch above video of a small aquarium with lots off rocks and guy even stands on the Rocks also.and underneath bottom aquarium not fully supported as tank sitting on 2 pieces off wood fir extra demonstration of strength off glass tanks.
Generally the smaller the aquarium the thinner the glass and larger the aquarium, the thicker the glass so even stronger ,some glass is tempered so really strong but cannot drill as just will shatter I've read lots of times ( but I have read some say can drill tempered glass,but I've no experienced off trying to drill tempered glass but I think in my opinion it's false as cant drill tempered )
But anyway stack rocks in glass and if adding sand ,add sand after rocks so rocks on glass then sand around ,especially if adding 12 inch engineer gobies that continually moving sand as they called engineer gobies for a reason ha ha

awesome. I feel very confident now!

I literally have nothing under my rocks on the glass

but im only stacking 2 high on 1/2 inch glass

Yeah see a video like that and very hard to still have nervousness.
I've got alot off rocks smashed up and glued then mortared together and all weight just on one base rock touching glass and rock npt flat,lots of spiky bits so weight just on 6-8 points if remember correctly ,on each of the 2 large Rock structures
