Bad test resualts!
Hi all, i have a problem! A few days ago this tank tested ok, i took the filter out and cleaned the ceramic rings and filter media in old tank water and also removed the carbon that was inside the filter media and discarded it. I put the cleaned filter media and ceramic rings back in the filter and did a 40 liter water change on the tank. There is 2 young discus and 7 catfish in this tank. No other changes were made. Its a 100 liter tank.. It also has a sponge filter in it which i didnt clean. This morning before feeding time i tested the tank, and to my horror these are the results:
PH 6.4 Very low!!
High Range PH 7.4 but looked yellow, off the chart..
Ammonia 0.25
Nitrite 0.25
Nitrate 80!!!
KH 17.9
GH 196.9
I have no idea what on earth has gone wrong here, i am in the middle of a huge water change and im going to clean the sponge filter too this time!
Could anyone shed light on what could have happened here please???

I did a 70 liter water change and triple dose of prime, cleaned the sponge filter that was clogged full of junk! The readings on the tank 9 hours later are better:
PH 7.6
High Range PH 7.4
Ammonia 0.25 i had fed them an hour before test..
Nitrite 0
Nitrate 20
Tragedy averted! I have came to the conclusion that when i removed the carbon that was loose inside the filter media with a cork holding it in, i in turn removed all the good bacteria and spiked the cycle resulting in the bad test results!

You are SPOT ON , that is one of the reason i don't believe in carbon , it is a bit like becoming addict to pain killers ,you don't realize it until you take it away.
You also might have cleaned your first filter a bit too much , i usually feed half the normal food for three days after filter cleaning .
Good results .

Thanks Sayid
The fish are more happy now, swimming all over the tank again, i wondered why they were hiding the last few days, poor little things

ayyyy, just when all my trouble is gone, it is your turn ), at least your problem not lasting too long ^^. From my 25 years experience keeping other fishes and a few month with discus, I would only use carbon when I need to remove a few minor nasty things in the water, as active carbon constantly suck away much needed stuff for fish.

Hm, i wonder if its due to my Tuoq picking on my Melon. I have just been sitting watching them and she is being a right queen, nipping at him and pushing him around. Could he be off due to that do you think? She normally is very good but is being a bit bossy with him. And of course she is not showing any signs of sickness, and comes meets me at the glass each time.

One reason could be that discus being a schooling fish you need at least 6 of them together ( breeding couple is an exception ).

Well that could be true Sayid, and reading that makes me think, when i had more discus the Melon was a lot darker red in color. Now he has turned a faint orange. He is currently hiding behind the new plants sulking it seems, he keeps turning sideways and scratching himself on the plant. Both of them have been skimming of the plants. I was worried my PH is to low, its 6.8 and use to be 7.6, im not even sure why it changed. These 2 are not a breeding pair, i have sold my smaller discus and these 2 are what is left. I was planning on buying 3 more new ones in the coming months. Maybe it is because they are alone, there isnt much i can do about that atm its almost christmas. I hope he doesnt get sick

I have got a small bag of sea shells in my canister filter as a buffer for ph fluctuation ,you can put half a handful of sea shells or broken coral or oyster shells in a nylon bag or lady,s tights and put it in a corner of your tank and hopefully that will do the job.
