Water Testing For Your Aquarium or Pond
It is essential that you have your aquarium or pond water tested regularly. Maintaining good water quality is the single most important component in sustaining a thriving aquarium. It sounds simple to do, but most hobbyists quickly discover that maintaining high water quality is one of the most challenging aspects of the hobby. We carry out the water testing for you in our shop, while you wait. We put the results into a website and then this provides you with a comprehensive anaylsis of your aquarium or pond water, which includes details of how to improve anything that is incorrect. We test for a range of chemicals in the water these include Ammonia, Nitrite, Nitrate, pH, GH, KH, Phosphate, Iron, TDS, Salt, Magnesium and Calcium for reef aquariums. The website gives your water quality a score and also remembers your previous results so we are able to compare results. This is especailly useful in new set ups as they go through New tank/pond syndrome, where the ammonia, nitrite and nitrate levels become toxic. We would then add bacteria and wait for the bacteria to grow and eat these pollutants. This process can take upto 6 weeks, then you can add more fish. We reccomend that you have your water tested when you purchase new fish.
We make it so easy for you! £2 for a complete tropical test or £3 for a complete marine test - We can test all of these below
Ammonia - NH4
Nitrite - N02
Nitrate - N03
Nitrite is the next pollution in the cycle and is still toxic but not as toxic as Ammonia. This should be treated with live bacteria such as Sera Nitrivec. Water changes should be carried out on old tank water but if the whole volume of water is less than 6 weeks old we find it best to not waterchange, just be patient!
Ammonia is the first form of pollution that the fish produce and is the most toxic to fish. This should be treated with live bacteria such as Sera Filter Biostart. Then Toxivec should be addded to protect the fish. Carbon is also a good ammonia remover, you can add this directly to your filter in a net bag.
Nitrate is the last pollution in the cycle. This can make unsighlty algae grow in the aquarium and in high levels it can stress the fish making them unwell. This should be treated with Tetra Nitrate Minus. Water changes also help. Always make sure you treat your tapwater with Tetra Aquasafe first. 
pH, GH, KH
Phosphate - P04
Iron - Fe
pH is a measure of wether the water is acid, neutral or alkaline. GH is a measure of the general hardness. KH is a measure of the Carbonate Hardness.  All of these components results would depend on the type of fish that you are keeping. Marine aquariums require a hgih pH where as Discus aquariums require a low pH.
Phosphate is another form of pollution. This can make unsightly algae grow in your aquarium and in very high levels can stress the fish. High levels can be caused in many ways such as over feeding, infrequent water changes, poor quality tapwater, pH adjusters, plant food and poor quality fish food.
Iron is a measure of the plant food available to your freshwater plants. The optimum level for this should be 0.5 mg/l. If this is too low your plants usually go yellow and die. You should add a good quality plant food regularly. Make sure that the plant food does not contain nitrate or phosphate.
Calcium - Ca
Magnesium - Mg
TDS, Salt Gravity
Magnesium is a measure for the corals to grow, The level of magnesium shoul be 3 times the calcium so if calcium is 440 ppm then magnesium should be 1320 ppm. If your magnesium is too low then the corals will not be able to absorb the essisntial calcium that they need to grow.
TDS is a measure of the Total Dissolved Solids, this is essential when testing the quality of Reverse osmosis water and Freshwater Shrimps. Salt Gravity for marine aquariums should be beween 1.021 ppm and 1.025 depending on the type of stock. Salt levels in ponds should be 0.12% if plants are in the pond.
Calcium is a measure for the corals to grow. Calcium is for the growth of the skeletons of the coral. It can also affect the pH of the tank if the the calcium is too high it can decrease the alkalinty thus reducing the pH levels. An ideal calcium level is 440 ppm this can be obtained by adding a good quality calcium additive.
