The refined details make it look extremely light and aesthetically pleasing.<\/p>\n<p>You can be sure of meticulous workmanship with the utmost precision, as Opti Tank aquariums are manufactured by our professionals in Poland, at the Aquael manufacturing plant in Suwalki.<\/p>\n<p>The uniqueness of Opti Tank Rounded is evidenced primarily by its edges. Thanks to the use of special technology, the front edges are rounded and devoid of silicone joints. This eliminated the vertical joints between the front glass of the aquarium and the side glass and gave an unprecedented visual effect.<\/p>\n<p>This makes the boundaries between the outside world and the arrangement in the aquarium blur, and the inside of the tank can be admired from all angles.<\/p>\n<p><strong>Opti glass transparent from all angles<\/strong><\/p>\n<p>The uniqueness of the Opti family of aquariums is determined by the type of glass used. Opti glass has been subjected to a special de-gelatinization process, in which a colorless effect is achieved. The glass is devoid of greenish coloration and has a high light transmission rate. As a result, it perfectly reflects the natural colors of plants and animals and creates the effect of crystal clear water.<\/p>\n<p>Tanks made using this technique are ideal for creating spacious and open arrangements. They provide a unique visual effect &#8211; the water, together with the arrangement, gives the impression as if suspended in the air.<\/p>\n<p>The top edge is polished, so smooth and safe to use.<\/p>\n<p>The model has a discreet, matching cover. It performs utilitarian functions &#8211; it protects the water surface from the deposition of dust and dirt. The lid can be conveniently tilted to access the inside of the tank, for example, when performing service.<\/p>\n<p>At the same time, the cover is almost invisible and does not disturb the proportions of the tank. Nothing draws the eye away from the plants and fish inside!<\/p>\n<p><strong>Aquariums from the Opti Tank Rounded line<\/strong><\/p>\n<p>Aquariums from the Opti Tank Rounded line are cube-shaped and come in 3 sizes:<\/p>\n<ul>\n<li>Opti Tank Rounded 20 &#8211; 25 x 25 x 30 cm, 19 l<\/li>\n<li>Opti Tank Rounded 30 &#8211; 29 x 29 x 35 cm, 29 l<\/li>\n<li>Opti Tank Rounded 70 &#8211; 39 x 39 x 45 cm, 68 l<\/li>\n<\/ul>\n<p>The tanks can be used both by lovers of nano aquariums and admirers of larger arrangements. One thing is certain &#8211; your aquarium will allow you to marvel at the beauty of the arrangement from any perspective!<\/p>\n<p>In addition, you can choose the color of the finish. Decide between classic colors: white and black, from which the elements supporting the cover are made. These small details can discreetly relate to the nature of the arrangement or the room in which you place the tank.<\/p>\n<p>In each package you will also find a properly fitted mat under the aquarium. It will allow you to comfortably and stably set the tank on the ground, which will affect the durability and safety of the tank. The mat protects the tank and reduces the transmission of vibrations from the substrate.<\/p>\n<p>For arranging Opti Tank Rounded tanks, the accessories will work great:<\/p>\n<ul>\n<li>FAN internal filter<\/li>\n<li>Lighting: Leddy Slim, Leddy Slim Duo, Leddy Smart Day&amp;Night<\/li>\n<li>UltraHeater Day&amp;Night heater<\/li>\n<li>&#8230; and many others from Aquael&#8217;s wide range of products.<\/li>\n<\/ul>\n<p>If you want to treat the Opti Tank Rounded as an open tank, then you can use the new FZN PRO Cascade Filter. In this case, you will not be able to use the lid from the set.<\/p>\n<p><strong>Notes<\/strong><\/p>\n<p>The product is made of glass, may be dangerous.<\/p>\n<table width=\"591\">\n<tbody>\n<tr>\n<td style=\"text-align: center;\" width=\"172\">\n<\/td>\n<td style=\"text-align: center;\" width=\"72\">\n<p><strong>Opti Tank Rounded 20 white<\/strong><\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"64\">\n<p><strong>Opti Tank Rounded 20 black<\/strong><\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"75\">\n<p><strong>Opti Tank Rounded 30 white<\/strong><\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"71\">\n<p><strong>Opti Tank Rounded 30 black<\/strong><\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"67\">\n<p><strong>Opti Tank Rounded 70 white<\/strong><\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"71\">\n<p><strong>Opti Tank Rounded 70 black<\/strong><\/p>\n<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: center;\" width=\"172\">\n<p>Index<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"72\">\n<p>131285<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"64\">\n<p>132458<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"75\">\n<p>131286<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"71\">\n<p>132459<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"67\">\n<p>131287<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"71\">\n<p>132460<\/p>\n<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: center;\" width=\"172\">\n<p>Aquarium capacity [L]<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"72\">\n<p>19<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"64\">\n<p>19<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"75\">\n<p>29<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"71\">\n<p>29<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"67\">\n<p>68<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"71\">\n<p>68<\/p>\n<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: center;\" width=\"172\">\n<p>Dimensions [cm] (width x depth x height)<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"72\">\n<p>25&times;25&times;30<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"64\">\n<p>25&times;25&times;30<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"75\">\n<p>29&times;29&times;35<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"71\">\n<p>29&times;29&times;35<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"67\">\n<p>39&times;39&times;45<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"71\">\n<p>39&times;39&times;45<\/p>\n<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: center;\" width=\"172\">\n<p>Glass thickness [MM].<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"72\">\n<p>4<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"64\">\n<p>4<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"75\">\n<p>4<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"71\">\n<p>4<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"67\">\n<p>5<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"71\">\n<p>5<\/p>\n<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: center;\" width=\"172\">\n<p>Type of glass<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"72\">\n<p>opti<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"64\">\n<p>opti<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"75\">\n<p>opti<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"71\">\n<p>opti<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"67\">\n<p>opti<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"71\">\n<p>opti<\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Opti Tank Rounded 20 White Aquarium Product highlights: Capacity: 19 l.
