I wanted to start owning a fish tank again as my grandkids love fish and decided to purchase the blue planet aquarium tank starter kit. I received it and decided to set it up. It comes with a 16l tank which is NOT glass but acrylic, filter, a fake plant and pebbles. It comes with instructions on how to put the filter together but no other instructions….my advise is to wash tank first, wash pebbles thoroughly under cold water in a pasta strainer until all dust and dirt gone before putting in tank and setting your tank how you like. I’ve now bought other plants and my Molly fish and food and I can say it’s been three weeks now and my fish are happy. So far so good. I recommend this tank.
