Other Aquarium Essentials

This webpage is dedicated to giving you options and showing you the most common aquarium essentials necessary when you start a new fish tank such as water conditioners, extra pumps, heaters, thermometers, test kits and more!  Not every aquarist will require every one of these items but they are definitely essentials for many aquarists depending on the size and type of tank you are setting up.

A good water conditioner is truly an aquarium essential when you are starting a tank and really should be kept on hand at all times.  A good water conditioner will not only neutralize chlorine in water but will also detoxify other metals in the water as well as help neutralize ammonia, nitrites, and nitrates and help provide a healthy, soothing effect on the fish.  It’s essential for a tank that is cycling but is also good to add whenever your fish show signs of stress or when you add new fish!

If you are setting up a new Aquarium then you will need a heater.  Here are a few models in the 25-1000 watt range.  Typically you will want about 50 watts for every 15 gallons of water so you might need a smaller heater (if you go to Amazon and search you will find plenty of options.)  You might be able to get away with even less in warm climates.  Most aquariums will do best at 78 degrees Fahrenheit.  Goldfish tanks and a few other types of aquariums do better at colder temps but either way a good tank heater is an aquarium essential.

Here’s the easy and fun way to clean aquarium glass, with no awkward long-handled tools or dunking your whole arm into the tank. In an elegantly simple design, strong magnets lock the two parts of the cleaner together through your aquarium’s glass, so the cleaning brush on the inside follows the handle on the outside. The inside piece has short plastic bristles to safely clean away algae, and the outside handle has an easy-slide felt surface. If the two sections should become separated, it’s no problem; the inside piece will float to the surface.

CaribSea Purple Up Algae Accelerator, 16-Ounce 16.45 t
CaribSea Purple Up Algae Accelerator, 16-Ounce

PurpleUp – uses a unique dual method approach to coralline algae acceleration. This approach is so unique that PurpleUp has been awarded a US patent (US patent No. 7,565,883). It contains ionic calcium; which immediately raises dissolved calcium levels in your aquarium water. At the same time Super Sea Calcium (a 10 micron aragonite powder derived from natural seawater) targets the live rock surface. This dissolves in situ; delivering calcium, strontium, magnesium, and carbonate right where it’s needed. PurpleUp also replenishes iodine; an essential element for coralline algae tissues that quickly becomes depleted in closed systems. PurpleUp is not a fertilizer, it does not promote the growth of nuisance algae.  Good Stuff!

aquarilogo240x240The Aquaripure filter is a comprehensive biological filter which will completely process all organic matter and remove all nitrates in an Aquarium.  The Aquaripure uses beneficial bacteria to break down invisible organic matter and nitrates completely into Nitrogen gas which then escapes into the atmosphere. This same process is even used by some water treatment plants to make wastewater safe for human consumption and to clean polluted water. The Aquaripure does this in an extremely safe and controlled environment and after the water from the Aquaripure is aerated there is nothing left but pure, clean, crystal clear water.
