White Fluval Spec 19L aquarium. In used condition but still looks almost new. This tank has been pimped up with an additional in tank container designed for this model. It allows for better media to be added or to replace the original foam sponge block (still in box) it would normally come with the tank from the manufacturer. This additional container cost £45 and has three separate compartments to hold media of your choosing. As the water in the tank runs down the container, I have pimped it with course, medium and fine sponges plus a bag of biogravel. This set up is perfect in order to supple the tank with great filtration and biological cycling. Comes with a spare pump. Please note you must cycle a tank first before adding any fish, if you do not know how to do this check out on you tube. I have included a used 25w heater, which works but you should change for a new one. Also I have taped some plastic to the lid as it had a gap and my Betta fish may have tried to jump out, you can remove this easily. Collection only and no returns.
