yes, but sand would be easier to use and it'll fill spaces better. Fill, wash in with water, fill again, rinse, wash, repeat until desired level of sand is attained.

Welcome Foxynev! Agree with @brokensword, sand is your best bet for a couple of reasons. As stated above, it will fill the gaps better and is less likely to cut/puncture the plastic pond. Just be sure you have the built-up framework level and tightly sealed with the ground. Did you use 4x4's for the framework? A weak frame will flex (I can speak from an awful experience) and the sand/filler will escape causing a major problem.

I have a 25 year old preformed fiberglass shell. I dug a 15" hole (just too much old concrete, brick, building debris in the ground to go deeper) and leveled the bottom of the hole with 3-4" of sand. Then I set the pond (25" shell depth) and built a Pavestone (preformed concrete blocks) wall around the perimeter, filling the void between the wall and the fiberglass shell with more sand as I went. It has held up very well over the years. However! If I could do it all over again - after learning what I've learned from this site - I would persevere in digging out all the garbage in the ground, make it 3 times as big, use a nice liner, cover the edges with beautiful mossy boulders, construct a half-dozen waterfalls, and put a plant-choked bog at each end, and add an array of LED lights both underwater and arching over the pond...

Put weight on the preformed pond. When you wet the sand with water to compact it, it will float and your calculations to make it level will be lost. Or add a little water and allow it to gradually absorb the sand.
