I have ordered twice from hirocks.com, the first time I was not happy, it was my fault for not reading the ad a little closer, I got great big rocks that were supposed to get placed in three different tanks.
, anyway after I got my 150 gal
tank I ordered another 60 lbs and it also was large rocks but that's what i wanted. If you want smaller rocks then order 2 30lb boxes not a 60.
I will order from them again should the need arise (MTS
