I have done that n my levels are fine as I did a water test?

I thought the test at the pet shop showed a reading of "minimum". Maybe I'm understanding this wrong, and my apologies if I do, but 0 would be no readings of ammonia and so forth, and minimum levels being some levels detected?
 
If in fact the test detected some levels, and you don't know how high the levels are (a constant exposure to as low as .25 ammonia can cause organ damage and even death) doing daily water changes would be best! If you have ammonia of .25 in your tank, doing a 50% water change would bring the level down to little over .1, which is not 0 but at least better than .25!?
 
Also, the fish that are still in your tank will continuously produce ammonia which will cause your levels to rise on a daily basis, only water changes will remove these until your tank is cycled.

I'm not sure on the exact reading as he didn't show me but all were in the top box of the sheet which Is the best it could be so I'm guessing the reading were nothing or extremely minuscule, I shall take some water down again tomorrow and get them to do another, 0 fish dead today and all are looking healthy to be honest so hopefully there on there way to being fixed

When you next get your water tested, make sure to ask for the exact results.

The "top box" on Pets at Home charts is 0 Ammonia, 0 Nitrite and I think our acceptable minimum of Nitrate is 40 round about.
 
Although make sure they leave it long enough to get a decent reading - a lot of my colleagues just shake and judge from that reading, they never wait long enough. Some of my colleagues use dirty vials too and some even use their fingers as stoppers when they shake the tubes! Not to mention some don't even shake the bottles
 
So watch and criticize!

Hi when did you swap over to a bigger tank ? as this can put tank into new cycle . I have just put new substrate in tank on last Saturday and having to do 2 water changes a day of 50% a time also added live bacteria to help . hope you get problem sorted soon
I never take advice from local pets at home as been given bad advice from them at the start
