Alright so what y'all think I should do ? Moved my large aquaponics tank to a better area and want to level it and make it so it doesn't sink in the ground again but stuck between trying my hand at pouring a little concrete pad for it or many just using pavers . What y'all think ?

A pad if it’s going to be its permanent spot. Eric

How level does it need to be to operate well? If it needs to be spot on, a pad would work better. If it can be off kilter a bit, pads would be easier to install and won't hurt anything if they settle some.

If you think you might be busting up concrete in the future you could get a couple railroad ties. Dig up under the grass and pack the dirt good with a sledge hammer.

If it were me I would do as suggested and get several railroad ties and get them leveled as these will cover more total ground to prevent sinking and are low cost and portable if you need to or want to move in the future.

what's a load of gravel cost you down there need gravel under concrete , but you could just as well compact a spot level with 6 inches of gravel and not have concrete

If you've not done concrete before and aren't sure if you want to try it, there's another way. On youtube there's some people doing "dry pour" concrete. Basically, you make a form (like 2x4s screwed together), dump the backs of quick crete in dry, and smooth it out. You get it how you want it (dry), then very lightly mist it. You need a hose nozzle that sprays a very fine mist. You do that a couple times to get a crust on top so water dropplets don't dimple it. Then you water it heavier. Water repeatedly and supposedly it sets up like normal.

I've always mixed it wet like normal, but I am curious about the dry method.

I've done both many times and would opt for the pad.

Check with your local gov't taxing body...around here if you put a PERMANENT pad in they tax you... pavers they don't.
But that's Illinois
