I receive e-mails from people every day seeking advice on Oscars. It seems that many people are confused by water testing and how to do it. I thought I would do a sticky on the forum to try and explain in four easy stages that testing the water is extremely easy, you certainly don't need to be a chemist to be able to carry it out.

There are many test kits on the market, I'm not going to list all of them. I use a company called Aquarium Pharmaceuticals. They make some excellent products for the aquatic world. I purchased the complete water testing kit. This included ammonia, nitrite, nitrate and pH. What I'm going to do is tell you how you test the water. I'm going to use ammonia as an example, I won't go through all the tests, once you know how to do ammonia, you will know how to do the rest of them.

An ammonia testing kit will comprise the solution that you add to the tank water (this could be two, or three bottles depending on the company use), a glass or plastic vile that you mix everything in, a colour card and instructions.

So here we go

1. Take your vile and swill it out in existing tank water, including the lid.

2. Put the correct amount of tank water in the vile. There is normally a line that indicates how much water to put in the vile.

With Aquarium Pharmaceuticals, the ammonia testing consists of two bottles. They are both indicated as #1 & #2, do not get it back to front.

3. Take bottle one and give it a quick shake and then add eight drops to your vile. Put the lid on and give it a quick shake. Do not plug the end of the vile with your thumb. Remember that we excrete ammonia through our skin, this could mess the test up completely.

4. Now take bottle two, quick shake and add another eight drops and then shake the vile. Now all you do is wait for five minutes and then compare the colour of the water to a colour card that you get with the kit. Zero ammonia will normally be bright yellow. The more ammonia that is present, the greener it gets.

I better just mention the nitrate testing. Sometimes you are required to shake the second bottle for at least 30 seconds and then shake the file for one minute after you have put all the solution in. Always read the instructions carefully. If you don't do the test properly, you may well get a false reading.

It's a straightforward as that. There is no need to be frightened when it comes to testing tank water.

ill try and buy that tommorow I have off!

hi there not really sure if this is the correct section to be asking this but i was wondering if it would be benificial to use a water filter on my tap water before adding to my tank as i have a fairly large filter and it is used reasonably inexpensively, (this is what i drink), and would i still need to use a chlorine removing chemical and if i did still use a chemical would there be any drawbacks? i'm 80% certain the human consumption filter i have removes it for me.
