Perfect 10 gallon tank!
5 Stars
Perfect 10 gallon tank!
I did a lot of research before deciding on this 10 gallon Marina tank. It was the tank kit that consistently showed up on internet reviews as one of the top tanks, especially for beginners. The filter is excellent and very quiet, the lighting is beautiful, and it's spacious digs for my son's Betta fish!I love that it came with small bottles of both the "Fluval Cycle biological enhancer" and the "Fluval chlorine/water purifier." My son had of course, against my advice, ran out and bought the betta fish before the tank was even set up. I was nervous because the tank had not yet been "cycled," meaning that it had not been filled with water, had the filter running, and had the chance to cycle to develop good bacteria on it's own, which typically takes about 4-6 weeks. Because this kit came with a bottle of the "Fluval Cycle biological enhancer," I was able to add the Betta fish the same day as setting up the tank (which is not recommended if you can help it, but it luckily worked out ok in this instance). I also used Poland Spring water to fill the tank instead of my tap water, along with of course adding the recommended doses from the bottles of the provided Fluval chlorine purifier and biological enhancer.The filter on this tank is excellent and I like that it has 3 separate cartridges, so you can change one every few months (never change them all at once or it will throw off the cycling of your tank). Only changing one filter at a time maintains the good bacteria growing on the other filters in the tank. There are also some youtube videos available on how to modify/replace the filter cartridges with other "media" so they don't need to be changed regularly, which I have already started doing. It's also better for the long term cycling of the tank to not get rid of cartridges on a regular basis (don't do it every 2-4 weeks like the directions say!), since there is so much good bacteria on the cartridges which helps the tank stay healthy, and you don't want to throw that away.I purchased a Eheim heater separately, which is a nice fit in this tank. I also purchased two thermometers separately, one digital one and one traditional one, and put them on opposite sides of the tank.Also, really important, make sure that you have a good place to put this tank, because once it has water in it, it is SUPER heavy, over 100 pounds! I had not thought of this until a few days before the tank arrived, so I ran out and purchased a fish tank stand at a local pet store which could support the weight. You don't want to risk just putting it on a regular piece of furniture because of how incredibly heavy it is once it is filled with water.One negative is that the lid does not have a hinge on it, it comes completely off when opening it all the way. It's a minor inconvenience as we mostly use the open feeding hole in the top right corner to feed our betta.Overall an excellent tank kit!! It's been over a month now, and our betta is happy and healthy and we are thrilled with our purchase!
