Water Quality

At Aquacadabra, we have a huge range of products to help you establish, replenish and monitor the water quality of your aquarium. Providing and maintaining suitable water parameters is fundamentally important to the success of your livestock, whether that be cold water, tropical, marine fish or corals.

We have split our water quality section into a number of sub categories to help you find and compare suitable products.

Should you need any advice, please feel free to contact us, we would be happy to help you with your selection.

With over 750 water quality products listed, you’ll be forgiven if you find the selection a little bewildering! You’ll find below a quick over view of each of the sub sections for this area of our website to help you on your way:

Aquarium Additives:

The water within which our fish live contains a multitude of minerals and trace elements, many of which are particular to a specific habitat. For example areas of the Amazon are rich in organic tannins, the waters of the African Rift Lakes are rich in calcium and sea water has an extremely complex mix of ingredients.

Over millions of years our livestock have developed to live in their specific habitat, therefore to ensure they are happy living in our fish tanks, we need to replicated this as closely as possible.

Aquarium Additives are used to replace the minerals and trace elements are either consumed by our livestock, or are filtered out as a by product of aquarium filtration. In certain circumstances, for example a reef invert system with a multitude of hard corals, it’s important to ensure all of the required compounds are provided in abundance, to ensure coral growth.

We stock a wide range of aquarium additives from various manufacturers to help you achieve this.

Dechlorinators:

If using tap water to fill your fish tank, it is important to remove any traces of chlorine prior to your fish coming into contact with the water. Water utilities add chlorine and chloramines to our tap water to inhibit bacterial development whilst the water makes its way to our taps. Whilst safe for us to consume, chlorine and chloramines are toxic to fish and can produce gill damage. As such it is important to dechlorinate any water that you add to your fish tank, and the easiest way to do this is by using a purpose made dechlorinator.

Many of the dechlorinators we have available also remove ammonia, nitrite and nitrate from your tap water, helping you to ensure you are adding water with the minimum amount of pollutants into your aquarium.

Bacteria Cultures:

When setting up your fish tank for the first time, the environment you create will essentially be sterile. If you add a number of fish to this fish tank, they’ll soon be producing waste which will start to break down. Without beneficial bacteria, the waste produced will create a toxic environment for your fish, causing stress and potential loss.

Bacteria cultures are a great way of adding beneficial bacteria to your aquarium, which naturally break down and waste products whilst helping to establish your filter. It is highly recommended that you use such a product, particularly at the early stages of setting up your aquarium, as the less stress you cause to your fish the more successful you’ll be.

Clarifiers:

As you’re aquarium establishes sediments and fine particles may appear, particularly after adding gravel or following maintenance. To help remove these we have a range of clarifiers which can be added to your fish tank’s water. These products are flocculants that encourage the fine particles to bind together, making them easier for your filter to mechanically capture.

Marine and Reef Salt:

There are a huge variety of marine and reef salts available on the market, with products tailored for use with tap-water or reverse osmosis water, designed for either fish only or marine invert systems. ‘Standard’ Marine salt includes all of the natural minerals and trace elements that will enable your marine fish to prosper. ‘Reef’ Marine salts tend to include additional trace elements and minerals that are designed to ensure coral growth and extra stability.

A tip is to buy in bulk if you have the space to store the salt as you’ll get great cost savings. Also invest in a water butt and keep it in the garage. This will allow you to mix large batches of salt at any time making water changes really convenient. Leave an airstone bubbling away and add an aquarium heaters a day or so before you need the water.

Treatments:

Unfortunately no matter how well we care for our fish, it is possible for a disease to break out our aquarium, whether that be transmitted from a new arrival in the aquarium or due to a water quality issue that has not been detected (so make sure you test your water!).

We have a large range of medications available to address the great majority of common ailments, such as white spot, fin rot, dropsy, parasites or bacterial infections. If you need any help selecting an appropriate medication, feel free to contact us.

pH Control:

As noted above, our ornamental fish have evolved to live in specific water parameters, and this includes the acidity or alkalinity (pH) of the water within which they swim. We have a number of products that can be used to set the pH of aquarium water at a specific level, locking it there – providing the perfect water conditions for our pets.

If you need advice regarding which pH product to use, we’re available 6 days a week and we’re happy to help.

A tip here is not to change the pH of your aquarium water too quickly, as your fish may not be able to tolerate too large a swing in water chemistry.

Reverse Osmosis (RO):

Sometimes the water from our taps simply isn’t right for our fish. If for example you live in the East Midlands and want to breed Discus, you’re just not going to be successful with the hard water we have. If you’re keeping a sensitive invert system, your tap water may contain phosphates that will cause nuisance algae and play havoc with your livestock.

An RO water filter will remove the vast majority of impurities that cause us problems from our tap water, by removing chlorine from the tap water, usually as small as 5microns, and by passing the water through a semi-permeable membrane which only lets through pure water molecules. For long term success with difficult species an RO system is a great investment, and again invest in a water butt to ensure you have plenty of water available when necessary.

Test Kits:

Monitoring your aquarium’s water regularly with test kits is a great way to ensure you can take precautionary action to any problems that may be developing, without which you’d only know there is an issue by livestock losses. As such we recommend you regularly test your Ammonia, Nitrite and Nitrate levels to ensure you fish tank is appropriate stocked and that your filter system if operating efficiently.

If keeping marine inverts, test for calcium and pH levels, not forgetting Magnesium and Strontium should you stock hard corals. If you monitor these parameters, you can ensure you’re providing the appropriate additives necessary for your livestock to thrive.
