LED Lighting and the unique Half Moon shape of these aquariums make a stunning combination! The LED Light provides a natural shimmering effect in the water, is energy efficient and is powered by a low voltage adapter.

Each aquarium has a clear plastic canopy with a feeding hole, and cut outs for the filter. The canopies also help to reduce water evaporation and keep fish inside the aquarium.

  • Black plastic framed bottom

Half Moon 20 and 30 include:

  • Half Moon 20 or 30 Aquarium

What protein filter can be used with the 30 gallon half moon tank?

Asked by: Julia
Hello, The SeaClone 100 protein skimmer is the only one we offer that will fit. You will not have room for another type of filter if you do use the skimmer because the acrylic canopy has a rigid hole cut-out that is only about 8.5 inches by 3.5 inches. There may be a glass canopy available in the future. The SeaClone is from our Instant Ocean brand products. InstantOcean.com

I just purchased a Half Moon 20 gallon tank from PetSmart (after I took back the 10 gallon to upgrade).

The 10 gallon kit came with a filter and the 20 gallon tank does not. I purchased the one the salesperson recommended and it is too big. Keep in mind I will be going back to purchase one from the same store. I did not see any MarineLand Fliters there. Do you have any suggestions?
Asked by: PaulaM
We would recommend the Penguin 100 and the Whisper EX20 for this system. The cut-out for the acrylic canopy meausres: 5.906" x 2.638" The filter you choose must fit this opening on the acrylic canopy. There may be a glass canopy available in the future. For the 30 gallon Half Moon the cut-out is 8.5" x 3.5" and we would recommend the Penguin 150 or Whisper EX30.

Any idea of future larger half moon aquariums coming?

I really like the look of the 30 gallon, but hesitate to go with anything smaller than a 40 gallon.
Asked by: ArizonaGreg
Hello, We are glad you enjoy the Half Moon design. There is currently no information on larger sizes being offered. We do offer the Euro curved front Aquariums in larger sizes. The 46 gallon one is item NV10460 with black trim or 11461 in oak trim. There is also an 80 gallon item 10805 in black trim. These offer the curved front design like the Half Moons, just not as rounded.

Is the half Moon OK for saltwater

Asked by: BobI
Hello, Are you referring to the glass Half Moon aquariums? We also have a very small 3 gallon Half Moon tank that would not really be advisable for saltwater. Assuming you mean the former, yes you can do a saltwater set-up. The kit currently only comes with an acrylic top that has some small opening in it for the heater and filter. You can use a filter if it will fit this size opening. We understand there may be a glass canopy available sometime in the future. The lighting is a small LED light that will not offer sufficient light for corals, but if you have fish only that would be fine. You could upgrade to a stronger light but it may be best to wait until a glass hood is available to do that.

Do the Half Moon systems provide adequate light for live plants?

Asked by: leelee
Hello, The Half Moon systems provide light more for fish-only display purposes. You could try growing plants that have low-light tolerance, such as Java fern.

How do I remove adhesive from inside the aquarium.

There is left over scotch tape adhesive from where the paper product labeling was attached in the tank. How do I remove the adhesive? I am afraid of using chemicals in the tank. I don't feel comfortable using a blade on the aquarium and besides I think it would be hard given the fact that th glass is curved. Any suggestions? Thank you.

Can aTimer be used for 10 gallon LED light Fixture

I have been unable to use a timer for the LED light fixture. When the timer is in the off position the led's light at low intensity. Please advise.
Asked by: unter2
Try a different timer. A timer just cuts off electricity so there shouldn't be an electrical flow when the timer is not engaged. Perhaps try and dig up a Christmas light timer somewhere and see if it works.

I just purchased the half moon 20 gallon tank with LED day/night lights and was wondering what the watts per gallon on this item is? what the watts

Asked by: Kkeeps2011
For years the Watts per gallon rule was used as a short cut to help people know which light was suitable for their needs. It was really a lucky coincidence that there was a correlation between Watts (energy consumed) and PAR/LUX (light energy produced). Watts are a measure of energy provided to the LED to create light. It does not measure how much light is actually being produced. Lumens, PAR and LUX are how light energy is measured. There are LEDs in the market that produce 40 Lumens (light energy) per Watt and there are LEDs that produce as high as 100 lumens per Watt. What is important for coral growth are the measurements PAR and LUX, not Watts consumed. PAR and LUX measure how much LIGHT energy is reaching the plants and coral. To put it in other terms: You have two cars. One car that goes 65 MPH and uses 16 gallons of gas per mile and the other car that goes 65 MPH and uses 6 gallons of gas per mile. They both go 65 MPH but one uses less gas to do so. Please visit our lighting overview for more information. http://www.marineland.com/LEDp2.asp...

I have a 10g half moon tank and I am looking to get a bigger one

i have a 10g half moon marineland tank that I purchased just over 1 year ago and I am really happy with it but i am now looking to get a larger one. When I checked out your specs on your web site the 10g is different and larger. My tank is 17.5 height x 17.5width x 11depth in inches. Just wondering if the specs you provide are for the tank itself or packaging it comes in? If it is the packaging can you provide the 20g and 30g actual tanks specs. Thanks
Asked by: Chubby
Hi, Thanks for asking your question. The dimensions for the Half Moon 10 were for the product in the packaging and the dimensions for the 20 and 30 were for the product without packaging. I've updated the specs and sizes to be consistent and now all dimensions of the dimensions for these are without packaging. The dims for the 20g are 23" x 12" x 24" and for the 30g are 26" x 14" x 28". Good luck with your fish keeping!

We have a 10 gal half moon tank, but no other parts. Is it possible ot order a lid and/or light?

Hi, yes you can get a replacement lid and light. My suggestion would be to get the Marineland LED Aquarium light. This light comes with Blue LEDs for the nightlight effect and rubber bumpers that you can put on so it will sit on top of the lid and not slide around. It will do a great job lighting the 10g Half Moon. The item number is 32996. You can find this light at your local PetSmart or independent retailer. The item number for the lid is R03182. You can order this item by calling Customer Service at 800.322.1266.

Either way, enjoy your aquarium.
