13 best gravel fish tanks

Product description

GloFish aquarium gravel and gravel accents are the perfect way to quickly convert any aquarium into an exquisite GloFish environment. These brightly colored gravels are designed to help create an underwater paradise for your fluorescent fish and stand out beautifully under blue LED lights. Your friends and family will love watching your GloFish aquarium come alive under GloFish lighting. GloFish aquarium Gravel sets the stage for a unique aquatic experience. This gravel not only provides a base for all your GloFish ornaments and plants, but it also looks magical under your GloFish aquarium’s blue LED lights. GloFish aquarium Gravel is available in a range of colors. Rinse gravel before using. For the best GloFish viewing experience, try using a blue wavelength light, like GloFish LED lighting, to give a uniquely fluorescent look, particularly in low or nighttime lighting. Traditional white aquarium lights (such as fluorescent or halogen lights) work well for daytime use. GloFish fluorescent fish absorb light and then re-emit it, so they will appear brighter and more vibrant as the amount of light is increased. GloFish fluorescent fish are born brilliant. They get their natural, vibrant color from their parents and are not injected, painted or dyed. Enhanced by a full range of aquarium kits, lighting, decor and accessories, GloFish products create a complete underwater fluorescent experience that appeals to all ages and levels of expertise.

• aquarium GRAVEL: GloFish aquarium Gravel creates a colorful base for all your GloFish ornaments.
• RANGE OF COLORS: Choose pink, green, white, black with fluorescent accents, or a mix of colors.
• BASK IN THE GLOW: Fluorescent-accented gravel stands out under GloFish blue LED lights.
• HIGHLIGHTS YOUR TANK: Use as a substrate or accent, along with GloFish plants and ornaments (sold separately).
• EXPERIENCE THE GLO: GloFish fluorescent fish and products create a complete underwater fluorescent experience.

User questions & answers

Question:	What type of rock is used in the gravel
Answer:	I have used the knife blade in my Cricut Maker to cut through thick leather, probably 3/16" thick. The problem I had was getting it to stick to my strong grip mat. (see caution at the end) Cutting smooth side down didn't stay. Placing rough side down destroys the mat. Transfer tape did not stick. I solved the problem with gaffer's tape! (available from Amazon). I use pro-gaff brand. Completely covered the rough side of the leather, placing the tape edge to edge, not overlapping. It stuck to the mat GREAT! CAUTION: IF THE LEATHER SLIPS WHILE YOU ARE CUTTING IT, YOU WILL DAMAGE YOUR MACHINE! I BROKE THE PLASTIC GUARD AROUND THE BLADE BEFORE I LEARNED TO USE GAFFER'S TAPE!
Question:	If I put this on top of my soil for my houseplants will it kill them
Answer:	If you don't have the Cricut knife blade and housing you will have to purchase the Cricut knife blade and then the replacement you have to change them out
Question:	How many bags for my 10 gallon tank
Answer:	Yes, this blade is for the New Cricut Maker Machine, which is the only machine that uses this blade due to the type of technology that Provo Craft created for this machine.
Question:	Can i use it for my succulent plants? Thanks a lot
Answer:	As far as the expressions parts list no it will not fit

Experience the Glo!

GloFish were originally bred to help scientists in detecting environmental pollutants. By adding a naturally derived fluorescence gene to the fish, scientists hoped to quickly and easily determine when a waterway was contaminated. Scientists soon realized the public’s interest in sharing the benefits of this research and GloFish were officially brought into the marketplace.

GloFish acquire their fluorescent color via a fluorescent protein gene that they inherit from their parents and pass on to their offspring through traditional breeding. Because of this, each line of GloFish originates from a single fish. For example, all Starfish Red Danios are descended from a single red fluorescent zebrafish.

GloFish are available in 3 species: GloFish Danio, GloFish Barb, and GloFish Tetra. Aside from their brighter disposition, each species is identical to their non-fluorescent counterparts. This includes everything from general care and temperature preferences, to growth and nutritional needs.

GloFish come in six stunning fluorescent colors including Starfire Red, Sunburst Orange, Electric Green, Cosmic Blue, Galactic Purple, and Moonrise Pink.

Question:	About how many cups of rocks is this
Answer:	That’s all physics. So to siphon water back to the tank you would do the same process as you did to get it out. The only difference is that you will need to have the water container you intend to put back in the tank elevated above the tank where you want the water to go. This thing has some powerful suction - so it may blow your substrate or sand all over the place if you aren’t careful.

User questions & answers

Question:	Will these work under a blacklight
Answer:	I did not test them under black light but they are ordinary stones and I have my doubts that they will work under black light.
Question:	How many bags do you think it would tale for a 10 gallon tank
Answer:	I have a 1 gallon tank for a beta fish and 1 bag is fine. You may want to start with about 4 bags and decide if you want more. They are much larger than the standard colored rock. The Bestgoo rocks are very cool and you only need a minimal amount to create a cool looking aquarium.
Question:	How many bags would I need for a 5 gallon aquarium? It's 10" x
Answer:	I always ended up with a gallon ziplock bag of my rocks for my 10gallon fish tank. So i'd get 4 or 5 'bags' of these for yours
Question:	How difficult is it to do weekly/monthly cleanings? Is waste very visable between cleanings, as apposed to using gravel
Answer:	They actually grow algae fairly easy. I have two nerite snails that spend a good bulk of their time trying to keep them clean. These rocks are also not very abundant, and if you have more than a five gallon tank, you will be spending quite the penny in trying to cover the whole tank with these rocks. That being said- they are quite lovely, given the right aquarium lighting.

User questions & answers

Question:	Can I mix this with the Carib sea product for growing live plants? How would you recommend layers or mix completely
Answer:	I was told that live plants cannot grow in rocks and was told to put in just the little starter soil pots and you can put the rock over it. Also to make sure to get live plants with good roots.

Answer:	Yes it can. I have a 75 gallon setup and I bought 100 lbs. My setup is a fresh water.
Question:	Is this actually a 50lb bag
Answer:	Yes it was a plenty I have a 250. Gallon tank
Question:	What’s the difference between this and the gravel at Lowe’s
Answer:	Not a whole lot. So here's the thing: You can EASILY go buy Lowe's pea gravel. The major issue is the pebble sizes. Generally, these bags made for aquariums are sized out to very specific ranges. The pea pebble bag at Lowe's is just a huge mix. I just set up my 75 gallon on the 9th of May and used Lowe's pea gravel. It just necessitated sifting out the superfine pieces. I used a pasta strainer for this. Just poured in the rock, and spun/shook it over a 5-gallon bucket. Got the superfine pebble pieces out. Added about 5 hours of work though, so ask yourself if it's worth it. I did 1 inch of dirt, with 1 inch of pea pebble to cap it off.
