placing heavy objects in

[Rich Jackson]

im in the process of starting my new tank and have some fairly heavy bits of hard scape to go in.
would I need to put polystyrene on the base of my tank(on the inside) to protect it ? then cover with substrate. dont want to crack the base!

Hi rich, i wouldnt put poły inside the tank myself. I normally put Some gravel in first then the rocka on top then top up with gravel/sub. Ive allways had 10mm glass tanks so never been to worried just płace them carefully down .

Some people on here have used something similar to a yoga mat. Might have been Mike Appleby with his bookcase tank, 259ltr I think, journal.

Just checked, It was in flygja's journal '120cm new scape'

Egg create for me to

egg crate. now why didn't I think of that.
that will do nicely!

I glue sheets of rubber(yoga mat etc can be used) to the base of the rock to make a nice stable pad several layers thick, this will not crush like eggcrate or float up later.

 

[Rich Jackson]

wouldn't have thought eggcrate would float with 25kg on top of it?

If you ever need to move it and adjust anything, which is better?
Anything loose is going to move around, if you pull up plant roots later, do you think the roots will get entangled in the foam or crate? Not an issue in marine systems. But in planted tanks, it can be.
I've have plenty of set ups where I've had to move things later on for many reasons. 25kg can also crush eggcrate unless you are gentle and if the rock has poky points, it'll also cause issues, or if you want certain angles, that cause more tension on the crate.
I'm not saying it does not work, I am saying there are better methods to do this.

 

[Rich Jackson]

I see your point. it does seem planted systems are far more hands in than marine. take there are no issues with things leaching out of the foam mat?

the egg crate marin guys use will be fine, just glue at the angle you want or use putty.
if you have an angle grinder or a friend that does use that the get a flat bottom on the rocks then glue them.
