yeah, i go to home depot and use the gravel they sell. It's like 3.99 for either 20 or 40 lbs. Big difference but i forgot which size. It's a good deal.
no, nothing in particular, i used a mix of gravel and sand. Just picked out a color i liked. Poked holes in the bad and rinsed it out that way. I think it looks nice in the tank, a mix between gravel and sand.
I just bought 200 lbs of pea gravel from Home Depot for less than 14 dollars.
It was the dirtiest gravel Ive ever seen but for that price you cant really complain.
