imagitarium Aquarium Gravel Substrate River Rock 20 lbs.

These are just beautiful.I love the size. They are slightly polished so they are not going to absorb the grime which makes cleaning so much easier!I would absolutely recommend these.

Love these for fish tank substrate. Good size, makes cleaning easy. Gives a beautiful, natural & Earthy look! Great buy!

These rocks work fine in the aquarium. The colors look great. They do get brown algae faster than regular synthetic aquarium rocks, though. The one thing I do not like is how much dust is generated by these rocks. It does not all wash off with rinsing and ends up in the aquarium. The filter seems to take care of the residual dust, but there has to be some way to minimize it before the packaging process

I ordered two fo these ( 40 lb total) for the bottom of our 20 gallon aquarium. Used 2/3 of the rocks. They look great. The fish seem to like them and they lay well and hold down the plants and other decorations we added to the aquarium. Though we washed them prior to adding to aquarium anyway- they arrived clean and had very little residue on them. Very pleased with their color and quality.

Bought these rocks because of their size and their natural earthy color. I actually used them in a terrarium that I made out of a 5-gallon fish tank. I knew you would see the rocks from the sides of the tank, so I wanted it to look natural and I wanted them big enough to be seen. Looked great when I was finished. Actually, I like them a lot. I was thinking about getting more and using them in my 10-gallon aquarium with my fish. Good price too.

Great colors good quality but make sure you clean thoroughly! It will take several times to rinse and clean but the price and amount is good. I have purchased multiple times

I bought this for my big goldfish, as they love to suck gravel into their mouths and spit it out. There is a risk with larger bottom-feeding fish of choking if gravel can fit all the way into their mouth. The larger gravel will hopefully reduce this risk. It looks beautiful too, good colors and a decent number of smooth flat stones. I’ll probably also add some aqua soil before filling the new tank to provide some extra stuff for plants to grab onto.

I like the natural look of this stone
