Instructions recommend sand or sifted soil. I would lean towards the sand since it should flow in and settle better in the voids unless you can compact the soil. Support for the tiers seems to be a critical issue.

Yes I see that I think gravel dust will flow to all corners...I hope

For this reason iry to talk people out of these preformed things. They are not easy to set but there is a way you want to work it as one section at a time You want to over size the excavation so you can back Fill aproprietly.
Starting with the bottom. For that sand or a dry layer of mortar. And by dry I mean no water what so ever. Twist the unit back and forth setting it to the desired height. Once established play sand usually the white gradually will flow best. Start back filling and COMPACTING as you go as you get some of it set and your comfortable start adding some water this will finish compacting the sand and the moisture will find its way to the dry mortar, again while compacting keep working your way up. SO MUCH HARDER AND MORECOMPLICATED THAN IS LINEr.

Yes I can see it as you explain it getting higher and higher ...making sure its leavel as we go....thank you

More than just level while that is critical , what's more so is supporting under the shelves/ horizontal as sooner or latter you will step in and most preforms are unable to support the weight expecialy if it's a bit of a drop and the heel makes the impact . They crack so easily

 

[gerryman]

Yes...it is 7mm thick but I do see what your are saying ..thank you

I got rid of all my preforms, over time cracked, heaved, finally tossed.

Hi..and what thickness was your preformed and how many ltrs/gallons

I've had a 75 gallon with lotus in it for years. Hubby was pulling weeds and stepped in it. Will be replacing it later this summer with a stock tank
