ok my tank is in trouble so i'm going to give you all the details and hope you can help me i have a 30 (uk) gallon tank heated to 27c filtered with bog wood and real live plants, plastic bridges and caves for hiding in, as my fish are ill i have been using melafix everyday (told to use it for 7 days) for the last 3 days all of them have fin rot (i think) and the rainbow is covered in a gooey thick gel stuff and have loads of bits on them that look like little air bubbles, i have 1 angel 2 molly's 1 rainbow fish 1 balloon ram and a plec, they are fed a varied diet of live/flake/frozen and algae wafers, i treat the water every week and do a 20% water change every week and treat the tap water before adding it to the tank i only ever wash the decor in the old water, i just tested my water and it came out...
G.H-180
K.H-240
P.H-8.0
NO2-0
NO3-40
i no these are not right so what can i do to get it back to normal?

sorry no2 is nitrite and no3 is nitrate
my fish are dropping like flies! yesterday i had my guppy (sparkle my favourtie made me cry) my balloon ram, my rainbow fish and this morning my angel has died! please can any help me or tell me what i am doing wrong or how to save the last of them, i adore my fish and don't want to loose anymore of them!

i don't no if i'm just trying to shift the blame but i bought my fish from 2 different stores the 1st lot were fine til i started adding fish from the other store, could this be causing it?

mohammed- yes i cycled for 5 weeks before i added any fish and tested the water was great til i added these new fish from the other store, then the g.h and k.h just crept up, and the disease spread fast!
 
"covered in a gooey thick gel stuff and have loads of bits on them that look like little air bubbles"

this sounds like an infection that spreads from fish to fish called "ick" [short for some longer latin name].....A water treatment sold at Pet/fish stores can fix it, but I think once a fish has it, it's done for.

Did you add a new fish in the past month or so? It might have been a carrier.
 
Firstly did u do the nitrogen cycle before you added the fish in, the nitrate and ammonia should have been in 0 before you added the fish.

You have to start all over again search for nitrogen cycle in google and do the steps it tells you to do. Fishless or Fish cycles are ok
