Great Tank, Like Hinged Hood.  Make Sure Pump Tube is Pressed Down Tight.
4 Stars
Great Tank, Like Hinged Hood. Make Sure Pump Tube is Pressed Down Tight.
There are several components to this aquarium to review.Firstly, the tank itself. It seems made well, simple enough.Now the hood. It has perforated cutouts for a filter and such. It also has a rectangular feeding hole near the front. There are extra spaces in the back for the light cable and air tubing if so desired. The lights actually have to be placed into their respective slots on the underside of the hood and there is a channel for the cord. The light cord can come out the left or right side, depending on preference. There are also 2 hinges that need to be installed. We found installing them onto the hood first worked easier than putting them on the tank's rim first. Just make sure that the front lip of the hinge clip (shorter side) goes under the tank's inner rim or the hood will not go down flat/sit flush. I like the hood overall, but I am concerned about the light strips constant contact with water. They're not submerged in the water, but they stay wet nonetheless.The heater is not being used, so I can not comment on that. I did stick the exterior temperature strip on the outside of the tank.Now onto the other accessories. The fishnet is basic, simple. Tjere is also some aquarium starter to make tap water safe and a small sample of fish flakes. I highly recommend having your own fish food and aquarium solutions.The decor is sparse. They actually gave me the wrong decor for my tank. I did get the boxwood gravel mat, but the rest of the plants that were in my kit were the "GloFish" plants. They're really bright and cheap looking and are better suited for the GloFish version kit, which they are actually intended for. If I had wanted the GloFish accessories, I would have chosen the GloFish kit. All the rest of the decor in my picture was from my smaller aquarium or ones that I purchased separately. I'm glad I had my own stuff because the included decor is pretty chinsy.Lastly we're onto the "Whisper" filter system. Whisper is a bit of a stretch, more like humming filter. As you can guess this is not as quiet as they make it sound, but it is tolerable... well at least now it is. I did have an issue w/the filter being super loud for days. I was so annoyed because it sounded like a small aircraft taking off in my dining room and it could be heard throughout the house. I almost dropped the star rating severely because of the amount of noise this thing was making. I decided to tinker w/the filter system again to see if I got a defective one or if it was some other issue. I'm glad I did because it's way more quiet now, not a Whisper, but definitely not obnoxious. The tube that presses down into the pump had somehow gotten slightly loose. This was causing vibration and also the pump gear wasn't catching like it should. The result was the filter was super loud. Once I tinkered around and pulled the tube back up and pressed it back in until it clicked, then the noise dropped drastically. Also, I found that I can not use the bio sphere filter type mediums in the back of the filter either because they cause vibration too. The pump comes w/1 Large size filter. Make sure to buy/order more of those too for monthly changes.

Reviewed in Mexico on November 18, 2018
Es un buen inicio ya que tiene todo lo necesario aunque en mi caso fue para substituir un pequeño acuario ya que mis peces estaban creciendo. Me parece que al filtro le falta capacidad de filtrado ya que entiendo que si el acuario es de 20 galones el filtro debería poder limpiar 60. Aunque ya lo apoye con otro filtro interno (del acuario anterior que me ayudó a acelerar el ciclado) y un producto que se llama Purigen (recomendado) Igualmente al filtro se le rompió la válvula de regulación de agua haciendo que no subiera por el tubo, pero con un poco de cinta teflón lo repare. Lo demás está bien. El calentador está preconfigurado para la temperatura y no se puede cambiar aunque se mantiene entre los 24 grados. En resumen me agrado la compra y la tapa con luces le dan muy buen aspecto. Ahora que bajo de precio me dan ganas de comprar otro jaja.

Excelente precio por lo que recibes. Las plantas artificiales son muy bonitas y de excelente calidad, nosotros cambiamos algunas solo por gusto, pero el surtido que incluye es más que suficiente tanto en variedad como en cantidad. No me gusta que el filtro whisper funciona con cartuchos desechables, intentaré adaptar algún filtro de gruesos y biológico que se adapte a mi gusto. En general, muy satisfecho con la compra, de hecho ordené también la versión Glo que también está muy bonita.
