You should go for it I do it all the time. All the changes I have done in the past 4 years I probably could write a book on it or do the changes in my sleep. I guess that is what happens if you like to tinker and the only half only allows 1 tank setup . I got the tank with nautal gravel and soon there after switched to black gravel. Then a year or so later I wanted to try sand so switched to white sand. The white sand I had was very fine and at that time I had HOB filters and had problems with sand burning up the impellers/motors so I switched to quickete medium grade sand. Never really liked the look of that and ended up upgrading to canisters so I recently switched to black sand. The only beef I had with the black sand is cost vs. the other types but it really makes the colorful fish like yellow labs and peacocks pop.

Size
When selecting your gravel you need to take into consideration everything that is going into your tank. High water flow angled downwards can cause a problem with tiny gravel. For ground walkers and snails small gravel may be the better choice. Plecostomus will love to munch on large pieces of gravel as they suck off the algae and many shrimp enjoy holding the large pieces in their many hands as they eat. Plants can easily spread their roots in both sizes, and algae can sink further into large gravel. Some fish even like to burrow into small gravel!

Ultimately smaller gravel need less, but more difficult, maintenance and are favored by most creatures. If however you own only free swimming fish and cleaner shrimp large gravel may be more your style. If you have tank mates who require different gravel you can even get two smaller bags of each, getting the benefits of both.

Color
While this is a choice of preference we still want to make sure new owners don't buy without thinking ahead. Sure green gravel can look beautiful and provide a rich background. Add in a couple plants and there's suddenly too much green. Likewise with black gravel it may be too dim if you have dark fish with few decorations. Remember the aquariums are supposed to be unique and vibrant. Try a color you don't see every day or even mix two colors together. Solid black combined with grey stones can give you a rich charcoal effect while green and pink produce an uplifting spring time vibe.

Savvy owners can even match and contrast their gravel with their fish. Everyone knows the combo of glow fish and black gravel. Dazzle your visitors by contrasting black and red fish with a lighter color. Conversely white/silver fish with dark colors can make a beautiful pairing.

Depth
If you do not want any live plants and have few scavengers, just an inch will serve your tank well. This will save you both space and money. For those tanks full of plants and various burrowing fish a 3 inch deep bed creates a more suitable environment I bought a 10gal aquarium about 6 months ago I had bought 4 glow fish and 2 neon tetra and the black light for the glow fish. The glow fish would hide under the filters and then after about 1 week they started dying I tested the water with the test strips and it was fine I went to petsmart with a water sample they said it was fine and replaced the fish about a week later it happened again so I got different fish 2 none tetra 2 red lid tetra and then petsmart sold be a bunch of chemicals for the tank I have done complete water changes bought new gravel and my fish keep dying please help
