Water change needed!

After consulting Mr. Fox he informed me that the water was filthy and it needed changing. After much instruction from the North road aquarium they taught me all i needed to know, which is exactly what i wanted as the Havant aquatics centre didnt tell me diddley squat! I have now got an information sheet showing what all the levels have to be at. Turns out they told me a figure way to high for the salt in Havant (never going there again!!!) SO ive now changed the water and replaced the cleaning materials and Simone is being a scientist and doing all the testing she was loving it :D All the values came out in the green which is great. Apart form the the Gravity (salt content) that was in the red and that is because of Havant aquatics centre. Shouldnt be too much of an issue i will slowly lower the gravity over the next week till its in the green, i just hope none of the fish get any parasites :(
